3-Way Multi Cloud Infrastructure Management With Terraform HCL

A Stronger Digital expertise mandates better Data Authority. Data plays a major role in different aspects of our business especially since the rise of Cloud computing technologies. Traditional storage systems are increasingly losing their charm while Cloud Storage infrastructures are being explored and supported more with innovative advances. However, Cloud Infrastructure can easily get too painful too quick if one isn’t rightly equipped for its management. Therefore, it’s imperative that we discuss and understand about Cloud computing technologies, their key service providers and most importantly the right means to manage the Cloud infrastructure.Peeping Into the Wonders of Cloud computing:Cloud computing, as it is very well known in recent times, is the delivery of computing services including – servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”). We saw how during the disruptive reality of last two years, cloud provided us with not only business continuity but also faster innovation, flexible resources, and economies of scale. Some of the major ways in which cloud has change the digital landscape for good are:Economy – You Pay only for cloud services that you use,Better ROIs – Lower Op-ex and Cap-ex for even better service qualityAutomation – Form infrastructure management to regular deployments, everything is more efficient and automation-friendly.High Scalability – As the business grows in terms of clientele, the entire system can easily scale in no-timeIt is also a well-known fact that many major players have already established themselves as Cloud Infrastructure experts. Depending on the popularity and business merits of these cloud service providers, their share in the market varies (figure below)With the varying benefits and service feasibilities of the cloud vendors, business find it more economical to opt for multiple cloud infrastructures and invest in better expertise and resources to manage them all. One important tool that helps in this task is Terraform.Terraform – HCL and Multi-Cloud Infrastructure ManagementTerraform is a popular infrastructure-as-code (IaC) tool from HashiCorp for that helps with building, changing, and managing infrastructure. For managing Multi Cloud environments it uses a configuration language called the HashiCorp Configuration Language (HCL) which codifies cloud APIs into declarative configuration files. The configuration files are then read and provided an execution plan of changes, which can be reviewed, applied, and appropriately provisioned.To understand this better, we need to dive into the different aspects of Terraforms working that come together to manage our multi-cloud infrastructures.Terraform Plugins: A provider is a plugin that Terraform uses to create and manage our resources. It interact with cloud platforms and other services via their application programming interfaces (APIs).We have more than 1,000 providers in the HashiCorp and the Terraform community to manage resources on Amazon Web Services (AWS), Azure, Google Cloud Platform (GCP), Kubernetes, Helm, GitHub, Splunk, and DataDog etc. and also we can find providers for many of the platforms and services in the “Terraform Registry”.Terraform Work flow: Terraform – Workflow consist of 3 stages Write – Define the resourcesPlan – Preview the changes.Apply – Make the planned changes.2.1 Write: We can define resources across multiple cloud providers and services. For example, we can create a configuration to deploy an application on virtual machines in a Virtual Private Cloud (VPC) network with security groups and a load balancer.2.2 Plan: We can create an execution plan describing the infrastructure it will create, update, or destroy based on the existing infrastructure and our configuration.2.3 Apply: Based on our approval, Terraform performs the proposed operations in the correct order, respecting any resource dependencies. For example, if we update the properties of a VPC and change the number of virtual machines in that VPC, Terraform will recreate the VPC before scaling the virtual machines. 3. Terraform Cloud Infrastructure Management3.1 Installing Terraform (CentOS/RHEL)Install yum-config-manager to manage your repositories.sudo yum install -y yum-utilsApplying yum-config-manager to include HashiCorp Linux reposudo yum-config-manager –add-repohttps://rpm.releases.hashicorp.com/RHEL/hashicorp.repoInstall.sudo yum -y install terraform3.2 Building InfrastructureConfigure the AWS CLI from your terminal.aws configureEnsuring separate working directories for each Terraform configurationmkdir learn-terraform-aws-instanceChange into the directory.cd learn-terraform-aws-instanceCreate a file to define your infrastructure.touch main.tfComplete configuration – deploy with Terraform3.3 Change InfrastructureCreate a directory named learn-terraform-aws-instance and use the above configuration into a file named main.tf.Initialize the configuration.$ terraform initApply the configuration (the confirmation prompt needs ‘Yes’ as the response to proceed)$ terraform applyFor updating the ami of your instance the aws_instance.app_server resource needs to be changed under the provider block in main.tf byReplace the current AMI ID with a new one.Finally, post-configuration-change, again run terraform apply to see the change on existing resources3.4 Destroy InfrastructureThe terraform destroy command terminates resources managed by our Terraform project. Destroy the resources which we createdBy this way, we can Build, Change and Destroy Various Cloud infrastructure (AWS, AZURE, GCP etc.) by using Terraform HCL .ConclusionManaging a single cloud infrastructure for private and public business purposes can be helpful. It seems humanely impossible to juggle between multiple cloud vendors. Therefore, external help in the form of Terraform is highly valuable for the business to maintain their bandwidth for consistent innovations. The 3-way process to ensure efficient multi-cloud infrastructure management is a gift that would easily make Terraform an essential weapon in our digital arsenal.

5 Key Motives to Adopt a Cloud-Native Approach

While some may argue that cloud-native history has been building for a while, it was companies like Amazon, Netflix, Apple, Google, and Facebook that heralded the underrated act of simplifying IT environments for application development. The last decade saw a bunch of highly innovative, dynamic, ready to deliver, and scaled-at-speed applications take over businesses that were stuck in complex, monolithic environments, and failed to deliver equally compelling applications. What dictated this change in track was the complexity and incompetence of traditional IT environments. These companies had already proven their competitive edge with their knack in identifying and adapting futuristic technology, but this time, they went back and uncomplicated matters. They attested cloud-native to be “the” factor that simplified app development if we are to continue this trend of data overload. Their success was amplified by their ability to harness the elasticity of the cloud by redirecting app development into cloud-native environments. Why Is Cloud-Native Gaining Importance? Application development has rapidly evolved into a hyper-seamless, almost invisible change woven into the users’ minds. We are now in an era where releases are a non-event. Google, Facebook, and Amazon update their software every few minutes without downtimes – and that’s where the industry is headed. The need to deploy applications and subsequent changes without disrupting the user experience have propelled software makers into harnessing the optimal advantages of the cloud. By building applications directly in the cloud, through microservice architectures, organizations can rapidly innovate and achieve unprecedented business agility, which is otherwise unimaginable. Key Drivers for Organizations to Going Native 1. Nurtures innovation With cloud-native, developers have access to functionally rich platforms and infinite computing resources at the infrastructure level. Organizations can leverage off the shelf SaaS applications rather than developing apps from scratch. With less time spent on building from the ground up, developers can spend more time innovating and creating value with the time and resources at hand. Cloud platforms also allow the trial of new ideas at lower costs –through low-code environments and viable platforms that cut back costs of infrastructure setup. 2. Enhances agility and scalability Monolithic application architectures make responding in real-time tedious; even the smallest tweaks in functionality necessitates re-test and deployment of the whole application. Organizations simply cannot afford to invest time in such a lengthy process. As microservice architectures are made of loosely tied independent elements, it is much easier to modify or append functionalities without disrupting the existing application. This process is much faster and is responsive to market demand. Additionally, microservice architectures are ideal for exploring fluctuations in user demands. Thanks to their simplicity, you only need to deploy additional capacity to cater to fluctuating demand (on an individual container), rather than the entire application. With the cloud, you can truly scale existing resources to meet real-time demand. 3. Minimizes time to market Organizations are heavily involved in time-consuming processes in traditional infrastructure management- be it provisioning, configuring, or managing resources. The complex entanglement between IT and dev teams often adds to the delay in decision making, therefore obstructing real-time response to market needs. Going cloud-native allows most processes to be automated. Tedious and bureaucratic operations that took up to 5-6 weeks in a traditional setup can be limited to less than two weeks in cloud-native environments. Automating on-premise applications can get complicated and time-consuming. Cloud-based app development overcomes this by providing developers with cloud-specific tools. Containers and microservice architectures play an essential part in making it faster for developers to write and release software sooner. 4. Fosters Cloud Economics It is believed that most businesses spend a majority of their IT budget in simply keeping the lights on. In a scenario where a chunk of the data center capacity is idle at any given point in time, it demands the need for cost-effective methodologies. Automation centric features like scalability, elastic computing, and pay-per-use models allow organizations to move away from costly expenditures and redirect them towards new features development. In simple words, with a cloud-native approach, you bring the expenses down to exactly what you use. 5. Improves management and security Managing cloud infrastructure can be handled with a cluster of options like API management tools, Container management tools, and cloud management tools. These tools lend holistic visibility to detect problems at the onset and optimize performance. When talking of cloud, concerns related to compliance and security are not far off. The threat landscape of IT is constantly evolving. When moving to the cloud, businesses often evolve their IT security to meet new challenges. This includes having architectures that are robust enough to support change without risking prevailing operations. The loosely coupled microservices of cloud-native architectures can significantly reduce the operational and security risk of massive failures. Adopting Cloud Native for Your Business Migrating to cloud-native is a paradigm shift in the approach of designing, development, and deployment of technology. By reducing the complexity of integration, cloud-native provides a tremendous opportunity for enterprises. They can drive growth by leveraging cloud-native environments to develop innovative applications without elaborate setups. Organizations are looking at a lifelong means of creating continuously scalable products with frequent releases, coupled with reduced complexities and opex. Cloud and cloud-native technologies signify the building of resilient and efficient IT infrastructure minus the complications, for the future. By selecting the right cloud-native solution provider, organizations can develop and deliver applications faster, without compromising on quality. Conclusion In an era of limitless choices, applications that quickly deliver on promises can provide a superior customer experience. Organizations can achieve this through faster product development, iterative quality testing, and continuous delivery. Cloud-native applications help organizations to be more responsive with the ability to reshape products and to test new ideas quickly, repetitively.

5 Ways How DevOps Becomes a Dealmaker in Digital Transformation

The culture of DevOps-ism is a triumph for companies. DevOps has plundered the inefficiencies of the traditional model of software product release. But, there is a key to it. Companies must unlock the true DevOps tenacity by wiring it with its primary stakeholders – People and Process. A recent survey shows that most teams don’t have a flair for DevOps implementation. Another study reveals that around 78 percent of the organizations fail to implement DevOps. So, what makes the difference? Companies must underline and acclimatize the cultural shift, which erupts with DevOps. This culture is predominantly driven by automation to empower resilience, reduce costs and accelerate innovation. The atoms that make up the cultural ecosystem are people and processes. Funny story, most companies that dream of being digital savvy, still carry primitive mind-sets. Some companies have recognized this change. The question remains – are they adept at pulling things together? Are You in the Pre-DevOps Era, Still? It is archaic! Collaboration and innovation, for the most part, is theoretical. The technological proliferation coupled with cut-throat competition has put your company in a hotspot. You feel crippled embracing the disruptive wave of the digital renaissance. Also, you feel threatened by a maverick Independent Software Vendor – who is new to the software sector. If the factors above seem, relevant, it is time to move away from the legacy approach. The idea is simple – streamline and automate your software production – across the enterprise. It is similar to creating assembly lines, which operates parallel, continuous and in real-time. If you consider manufacturing, this concept is more than 150 years old. In software space, we have just realized the noble idea. Where it all started….. The IT industry experienced a radical change due to rapid consumerization and technological disruption. This created a need for companies to be more agile, intuitive and transparent in their service offerings. The digital transformation initiatives are continually pushing the boundaries to deliver convergent experiences that are insightful, social and informative. Further, the millennials who form more than 50 percent part of the overall IT decision makers globally are non-receptive to inefficient technologies and slow processes. They want their employees to work in an innovative business environment with augmented collaboration and intelligent operations. It is essential for the organization to follow an integrated approach for driving digital transformation, integrating cross-functionalities and enabling IT agility. DevOps enables enterprises to design, create, deploy and manage applications with new age software delivery principles. It also helps in creating unmatched competencies for delivering high-quality applications faster and easier; while accelerating innovation. With DevOps, organizations can divide silos facilitating collaboration, communication, and automation with better quality and reduced risk and cost. Below are the five key DevOps factors to implement for improving efficiency and accelerating innovation. 1. Automating Continuous Integration/Continuous Delivery DevOps is not confined to your departments. Nor it is just a deployment of some five-star tools. DevOps is a journey to transform your organization. It is essential to implement and assess a DevOps strategy to realize the dream of software automation. Breaking the silos, connecting isolated teams and wielding a robust interface can become taskmasters. This gets more tedious for larger companies. The initial focus must remain on integrating people in this DevOps model. The idea is to neutralize resistance, infuse confidence, and empower collaboration. Once these ideas become a reality, automation will become the protagonist. The question remains – How automation will be the game changer? This brings the lens on Continuous Integration/ Continuous Delivery (CI/CD). It works as a catalyst in channelizing automation throughout your organization. Historically, software development and delivery have been teeth-grinding. Even the traditional DevOps entails a manual cycle of writing codes, conducting tests, and deploying codes. This brings several pitfalls – multiple touchpoints, non-singular monitoring, increased dependencies on various tools, etc. How to Automate the CI/CD Pipeline? Select an automation server that provides numerous tools and interfaces for automation Select a version control and software development platform to commit codes Pull the codes in the build phase via automation server Compile codes in the build phase for various tasks Execute a series of tests for the compiled codes Release the codes in the staging environment Deploy the codes from the staging server via Docker An automated CI/CD pipeline will mitigate caveats associated with the traditional DevOps. It will result in a single, centralized view of project status, across stages. It drastically brings down the human intervention, moving you towards zero errors. But, is that all simple? Definitely no. It has its own set of challenges. Companies that are maneuvering from waterfall to DevOps, often end up automating wrong processes. How can teams avoid this? Well, have the following checklist handy. The frequency of process/workflow repetitions The time duration of the process Dependencies on people, tools, and technologies Delays resulting due to dependencies Errors in processes, if it is not automated These checklists will provide insights on the bottlenecks. It will help prioritize and automate critical tasks – starting from code compiling, testing to deployment. 2. The Holy Nexus of Cloud and DevOps You don’t buy a superbike to drive it in city traffics. You would prefer wide roads, less traffic to unleash its true speed. Then why do Cloud without DevOps? The combination of Cloud and DevOps is magical. Often, IT managers don’t realize it. Becoming a Cloud first company is not possible without a DevOps first approach. It is a case of the sum being more significant than parts. What is the point of implementing DevOps correctly, when the deployment platform is inefficient? Similarly, a scalable deployment platform loses its charm without fast and continuous software development. Cloud creates a single ecosystem, which provides DevOps with its natural playground. The centralized platform offered by Cloud enables continuous production, testing, and deployment. Most Cloud platforms come with DevOps capabilities of Continuous Integration and Continuous Delivery. This reduces the cost of DevOps in an On-Premise environment. Consider the case of Equifax – a consumer credit reporting company. They store their data on cloud and in-house data centers. In 2018, they released a document on the cyber-attack, which hit them in Sep 2017. Hackers collected around 2.4 million personally identifiable information (PII) of their customers. The company had to announce that they will provide credit file monitoring services to affected customers at no cost. Isn’t it damaging – monetarily and morally? But, what made hackers get access to such sensitive customer information? Well, per the website, there was a vulnerability Apache Struts CVE-2017-5638 to steal the data. Although the company patched this vulnerability in March 2017, it required more profound expertise and smarter process regime. If they had a DevOps strategy to redeploy software with continuous penetration testing more frequently, a cyber-attack could have averted. It is a genuine concern for any CIO to derive the value of cost, agility, security, and automation from their Cloud investment. The most common hurdle to this is the less compatible IT process. There other significant challenges too. Per a recent survey by RightScale, around 58 percent of Cloud users think saving cost is their top priority. Approximately 73 percent of the respondents believe that lack of skill expertise is a significant challenge. More than 70 percent of respondent said that governance and quality is an issue. The report also outlines integration as a challenge when moving from a legacy application to the Cloud. DevOps can standardize the processes and set the right course to leverage Cloud. DevOps in the backend and Cloud in the frontend gives a competitive edge. Cloud works well when your Infrastructure as Code (IaC) is successful. IT teams must write the right scripts and configure it in the application. Manually writing infrastructure scripts can be daunting. DevOps can automate scripts for aligning IT processes to Cloud. 3. Microservices – The Modern Architecture Microservices Without DevOps? Think Again! The sea-changes in consumer preferences have altered companies’ approach to delivering applications. Consumers want results in real-time, unique to their needs. Perhaps, this is why companies such as Netflix and Amazon have lauded the benefits of Microservices. It instills application scalability and drives product release speed. Companies also leverage Microservices to stay nimble and boost their product features. The main aim of Microservices is to shy away from the monolithic application delivery. It breaks down your application components into standalone services (Microservices). These services then must undergo development, testing, and deployment in different environments. The services’ numbers can be in 100s or 1000s. Additionally, teams can use various tools for each service. The resultant will be mammoth tasks coupled with an exponential burden on the operations. The process complexities and time-battle will also be a nightmare. Leveraging Microservices with a waterfall approach will not extract its real benefits. You must de-couple the silo approach to incubate the gems of DevOps – People>Process>Automation. Microservices without DevOps would severely jolt teams productivity. The Quality Assurance teams would experience neck-breaking pressure due to untested codes. They will become bottlenecks, hampering the process efficiencies. DevOps with its capability to trigger continuity will stitch every workflow through automation. 4. Containers –Without DevOps? Consider companies of the size and nature of Netflix that require to update data in real-time and on an on-going basis. They must keep their customers updated with new features and capabilities. This isn’t feasible without Cloud. And, on top of that, releasing multiple changes daily, will be dreadful. Thereby, for smooth product operations, Container Architecture is a must. In such a case, they must daily update their Container Services – multiple times. It entails website maintenance, releasing new services (in different locations) and responding to security threats. Even if you are a small to medium Independent Software Vendor operating in the upper echelons of the technology world, your software product requires a daily upbeat. Your developers will always be on their toes for daily security and patching updates. This a daunting task, isn’t it? DevOps is the savior. DevOps will hold back for your applications that are built in the Cloud. It will set a continuous course of monitoring through automation and ease the pressure of monitoring from developers. Without DevOps, Container Architecture won’t sustain the pressure. 5. Marrying DevOps, Lean IT, and Agile The right mix of DevOps, Lean and Agile amplifies business performance. Agile emphasizes greater collaboration for developing software. Lean focuses on eliminating wastes. DevOps wants to align software development with software delivery. The three work as positives; adding them will only augment the outcome. However, there persists a contradiction in perception towards adopting these three principles. When Agile took strides, the teams said that we already do Lean IT. When DevOps took strides, the teams said that we already do Agile. But, the three principles strive to achieve similar things in different areas of the software lifecycle. Combining DevOps, Lean and Agile can be an uphill task. Especially, for leaders that carry the traditional mindset. Organizations must revive their leadership style to align with modern business practices. The aim must be moving towards a collaborative environment for delivering value to the customers. Companies must focus on implementing a modern communication strategy at the workplace. It is necessary that they address the gaps between IT and the rest of the groups within an organization. They must be proactive in initiating mindful cross-functional relationships, backed by streamlined communications. The software development teams will then work as protagonists in embracing DevOps, Lean and Agile to survive the onslaught of competition. It is also essential to champion each of the above concept. This will ensure that we profit out of each component in the combination. Organizational leadership must relentlessly work to create a seamless workflow, while removing bottlenecks, cutting delays, and eliminating reworks. Companies haven’t yet fathomed the true benefits of DevOps-Agile-Lean combination. It needs time and the team of experts to capitalize on these three principles. Additionally, companies shy away from exploiting the agility and responsiveness of modern delivery architects – Microservices, in particular. This becomes a hindrance in reaping the full potential of the combination. The crux of driving DevOps-Agile-Lean combination is a business-driven approach. Continual feedback backed by the right analytics also plays a crucial role. It facilitates fail-fast, thereby, creating a loop of continuous improvement. Agile offers a robust platform to design software, which is tuned with the market demands. DevOps stitches the process, people and technology, ensuring efficient software delivery. Final Thoughts Adopting DevOps is a promising move. Above, we have depicted in 5 manners how DevOps is your digital transformation dealmaker. However, it can be nerve crunching. It takes patience, expertise, and experience for embodying its purest form. A half-baked DevOps strategy might give you a few immediate results. In the long run, it will deride your teams’ efforts. However, automation is the best way to sail through it.

An Introduction to Serverless and FaaS (Functions as a Service)

Evolution of Serverless ComputingWe started with building monolithic applications for installing and configuring OS. This was followed by installing application code on every PC to VM’s to meet their user’s demand. It simplified the deployment and management of the servers. Datacenter providers started supporting a virtual machine, but this still required a lot of configuration and setup before being able to deploy the application code.After a few years, Containers came to the rescueDockers made its mark in the era of Containers, which made the deploying of applications easier. They provided a simpler interface to shipping code directly into production. They also made it possible for platform providers to get creative. Platforms could improve the scalability of users’ applications. But what if developers could focus on even less? It can be possible with Serverless Computing. What exactly is “Serverless”?Serverless computing is a cloud computing model which aims to abstract server management and low-level infrastructure decisions away from developers. In this model, the allocation of resources is managed by the cloud provider instead of the application architect, which brings some serious benefits. In other words, serverless aims to do exactly what it sounds like—allow applications to be developed without concerns for implementing, tweaking, or scaling a server.In the below diagram, you can understand that you wrap your Business Logic inside functions. In response to the events, these functions execute on the cloud. All the heavy lifting like Authentication, DB, File storage, Reporting, Scaling will be handled by your Serverless Platform. For Example AWS Lamba, Apache IBM openWhisk.When we say “Serverless Computing,” does it mean no servers involved?The answer is No. Let’s switch our mindset completely. Think about using only functions — no more managing servers. You (Developer) only care about the business logic and leave the rest to the Ops to handle.Functions as a Service (FaaS)It is an amazing concept based on Serverless Computing. It provides means to achieve the Serverless dream allowing developers to execute code in response to events without building out or maintaining a complex infrastructure. What this means is that you can simply upload modular chunks of functionality into the cloud that are executed independently. Sounds simple, right? Well, it is.If you’ve ever written a REST API, you’ll feel right at home. All the services and endpoints you would usually keep in one place are now sliced up into a bunch of tiny snippets, Microservices. The goal is to completely abstract away servers from the developer and only bill based on the number of times the functions have been invoked.Key components of FaaS:Function: Independent unit of the deployment. E.g.: file processing, performing a scheduled taskEvents: Anything that triggers the execution of the function is regarded as an event. E.g.: message publishing, file uploadResources: Refers to the infrastructure or the components used by the function. E.g.: database services, file system servicesQualities of a FaaS / Functions as a ServiceExecute logic in response to events. In this context, all logic (including multiple functions or methods) are grouped into a deployable unit, known as a “Function.”Handle packaging, deployment, scaling transparentlyScale your functions automatically and independently with usageMore time focused on writing code/app specific logic—higher developer velocity.Built-in availability and fault tolerancePay only for used resourcesUse cases for FaaSWeb/Mobile ApplicationsMultimedia processing: The implementation of functions that execute a transformational process in response to a file uploadDatabase changes or change data capture: Auditing or ensuring changes meet quality standardsIoT sensor input messages: The ability to respond to messages and scale in responseStream processing at scale: Processing data within a potentially infinite stream of messagesChatbots: Scaling automatically for peak demandsBatch jobs scheduled tasks: Jobs that require intense parallel computation, IO or network accessSome of the platforms for ServerlessIntroduction to AWS Lambda (Event-driven, Serverless computing platform)Introduced in November 2014, Amazon provides it as part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. Some of the features are:Runs Stateless – request-driven code called Lambda functions in Java, NodeJS & PythonTriggered by events (state transitions) in other AWS servicesPay only for the requests served and the compute timeAllows to Focus on business logic, not infrastructureHandles your codes: Capacity, Scaling, Monitoring and Logging, Fault Tolerance, and Security PatchingSample code on writing your first lambda function:This code demonstrates simple-cron-job written in NodeJS which makes HTTP POST Request for every 1 minute to some external service.For detail tutorial, you can read on https://parall.ax/blog/view/3202/tutorial- serverless-scheduled-tasksOutput: Makes a POST call for every minute. The function that is firing POST request is actually running on AWS Lambda (Serverless Platform).Conclusion: In conclusion, serverless platforms today are useful for tasks requiring high-throughput rather than very low latency. It also helps to complete individual requests in a relatively short time window. But the road to serverless can get challenging depending on the use case. And like any new technology innovations, serverless architectures will continue to evolve to become a well-established standard.References: https://blog.cloudability.com/serverless-computing-101/ https://www.doc.ic.ac.uk/~rbc/papers/fse-serverless-17.pdf https://blog.g2crowd.com/blog/trends/digital-platforms/2018-dp/serverless-computing/ https://www.manning.com/books/serverless-applications-with-node-js

How Can Aziro (formerly MSys Technologies) Expertise Help You with SaaS, PaaS, and IaaS

Cloud computing has revolutionized how we provide IT software and infrastructure. Today, many software companies are interested in providing their applications and services in the form of a cloud service rather than packaging their software and licensing it out to customers. There are a number of advantages to this type of service delivery model.Customers have access to applications and data from anywhere. Just a direct connection to the Internet is necessary for a cloud-based application to run. Data is also easily accessible over a network. Data would not be confined to a simple computer system or the internal network of an organization. Hence, access is easy from any location.Cost will come down in this model. You no longer need advanced hardware resources to run an application. A simple thin client can access a cloud-based application from anywhere. The hardware resources to run the application resides in the cloud, and it can be used to profitably run the application on any number of systems. The thin client can include a monitor, I/O devices, and just enough processing power to run the middleware that accesses the application from the cloud.Cloud computing systems are highly scalable. You don’t need to worry about adding additional hardware to run an application. The cloud takes care of all of that.Servers and storage devices take up a lot of physical space. Renting physical space can cost quite a lot of money for an organization. You can, with the cloud, simply host your products and software on someone else’s hardware so as to save a lot of space on your end.Streamlined hardware infrastructure of the cloud will have fewer technical support needs.Since cloud computing takes advantage of a grid computing system in the back end, the front end doesn’t really need to know the infrastructure to run any application of any size. In simpler terms, the advanced calculations a normal computer would take years to complete can be done in seconds through a cloud-computing platform.Cloud ModelsCloud computing takes three major forms: SaaS, PaaS, and IaaS. They are expanded as Software, Platform, and Infrastructure as a Service. In the case of SaaS, users are given access to software applications and associated databases. The installation and operation of the software is done completely from the cloud, and the access through authentication is done from a thin client.Cloud provides the load balancers required to run the application by distributing the work across multiple virtual machines. This complex back end is not even visible to the end user, who simply sees the running application through a single access point. The SaaS applications can be in subscription model, in which you pay a monthly or yearly fee to get access to the application.In the PaaS model, the cloud provides a computing platform that includes typically an operating system (Windows, Mac OS X, Linux, etc.), programming languages required for software development, database, and web servers. These entities are all stored in the cloud. Instances of the PaaS model include Microsoft Azure and Google App Engine.In the IaaS model, you have as many virtual machines as you need on the cloud. A hypervisor, such as VMware ESXi, Oracle VirtualBox, XenServer, or Hyper-V are provided through the IaaS platform. Additionally, virtual machine disk image library, raw block storage, object storage, firewalls, load balancers, virtual LANs, etc., are all provided by the IaaS model. This helps any organization successfully deploy their applications on the cloud. The most popular IaaS provider is probably Amazon Web Services.Deployment ModelsThree types of deployment models exist in the cloud architecture. They are private cloud, public cloud, and hybrid cloud. Private cloud is managed and operated by a single organization internally. Significant amount of virtualization is required for a private cloud deployment, and that can increase the initial investment required. However, when deployed correctly, a private cloud could be highly profitable for any organization.Public cloud is rendered to the public as a service. For instance, Amazon AWS, Microsoft Azure, etc., are provided to the public to use and deploy their applications and infrastructure. This type of architecture requires you to analyze the security and communication concerns of the cloud.In the case of hybrid cloud, as the name implies, both private, community, and public cloud deployments could be there. In hybrid cloud systems, the advantages of both types of systems may be there. Various deployment models are available in the case of hybrid cloud: for instance, a company can store sensitive client data in private cloud architecture while deploying business intelligence services provided by a public cloud vendor.MSys’s Cloud ExpertiseAziro (formerly MSys Technologies) and its subsidiary company Clogeny have done several cloud-based projects in the past. We have analyzed the current infrastructure of clients, and provided a proper road map to cloud deployment. In implementation, we have taken care of the complete design of the cloud computing model, building test environments to check the validity of the design, and migration of apps and data to go live. We also provide fully functional cloud support through transition plans, service review, and service implementations.We have worked with some of the major cloud service providers in the industry including Amazon Web Services, Microsoft Azure, Rackspace, HP Cloud, Google Cloud, OpenStack, Salesforce, Google Apps, Netsuite, Office 365, etc. We have also helped organizations take advantage of their data by providing big data services. Leading companies in storage, server imaging, and datacenter provisioning have been our clients since our inception in 2007. In private and public cloud deployments, a few of our clients include Datapipe, Instance, and Netmagic.Our cloud-based product is known as PurpleStrike RT, which is a load-testing tool that utilizes Amazon’s EC2 platform.ConclusionCloud computing may prove to be the most important technology for future’s IT deployments. Already many companies have moved to the cloud. Many more are in the process of slowly transitioning to the cloud.

Cloud Orchestration: Everything you want to know

Have you ever wondered how complex the online systems are? Systems such as online airline ticket booking system, Internet Services, Scientific research data systems, social networking sites and more such online systems make an end user’s job simple. Actually, these systems have lots of complex structure with complex processes running in the background which make these systems work as a single workflow. Consider a case where a user is ordering a service by using an application hosted in cloud. The interface makes the entire process of ordering, approving, and provisioning look simple, as if it is a single application hosted on the same cloud. Most of the times, it is a set of applications hosted in various cloud environments, some to process the data and some to store data. Also, various platforms and infrastructure are involved in it. From user’s point of view it does not make a difference, but the service provider, whose system consists of various applications having a single interface, needs to manage the parts (modules of an app and various interlinked apps) of system hosted in various cloud environments. Managing all the parts of the system needs automation to minimize the admin intervention. So, what exactly does the service provider need to manage? Service providers need to take care that the system is up and running all the time. As the traffic grows, the system needs to be scaled by creating new environments. Creating a new environment involves functions such as spinning up a VM, adding new instances during an auto-scaling event with auto scaling groups and elastic load balancers, and configuring the OS. Automating all these functions is part of cloud automation process. The functions may also include deployment automation tools. It is a must for engineers to arrange these automation tools in definite order under specific security groups or tools. All this involves numerous manual tasks that engineers need to complete to create an environment. This is where cloud orchestration helps. Cloud Orchestration is a way to manage, co-ordinate, and provision all the components of a cloud platform automatically from a common interface. It orchestrates the physical as well as virtual resources of the cloud platform. Cloud orchestration is a must because cloud services scale up arbitrarily and dynamically, include fulfillment assurance and billing, and require workflows in various business and technical domains. Orchestration tools combine automated tasks by interconnecting the processes running across the heterogeneous platforms in multiple locations. Orchestration tools create declarative templates to convert the interconnected processes into a single workflow. The processes are so orchestrated that the new environment creation workflow is achieved with a single API call. Creation of these declarative templates, though complex and time consuming, is simplified by the orchestration tools. Cloud orchestration includes two types of models: Single Cloud model and the Multi-cloud model. In Single cloud model, all the applications designed for a system run on the same IaaS platform (same cloud service provider). Applications, interconnected to create a single workflow, running on various cloud platforms for the same organization define the concept of multi-cloud model. IaaS requirement for some applications, though designed for same system, might vary. This results in availing services of multiple cloud service providers. For example, application with patient’s sensitive medical data might reside in some IaaS, whereas the application for online OPD appointment booking might reside in another IaaS, but they are interconnected to form one system. This is called multi-cloud orchestration. Multi-cloud models provide high redundancy as compared to single IaaS deployments. This reduces the risk of down time. Key features of Multi-Cloud Model Flexibility to run applications on various IaaS platforms depending on the applications’ needs Higher redundancy than single cloud models thus reducing the down time risk Interoperability across multiple cloud environments Benefits of Cloud Orchestration Reduce overall IT costs: By reducing the number of administrators, to a larger extent, required per server By reusing the IT resources depending upon the business demands thus saving the cost for new purchase By providing the facility of paying for only those resources that are being used Improve delivery times and free up engineering time for new projects: By reducing the provisioning time from weeks to hours By increasing the capacity with the use of virtual servers thus avoiding the addition of physical hardware By providing self-service management facility for end-user Have smooth coordination between System teams and Development teams: By standardizing service descriptions and policies, and SLAs By building automated provisioning templates Make the Catalog of Services available through a single pane of glass: By aligning the business perspective with the IT perspective Conclusion Without cloud orchestration it is difficult to optimize cloud computing to its maximum potential. Owing to its multi-fold benefits, you can be assured that cloud orchestration easily helps service providers scale, reduce downtime risks and seamlessly align the various process for a great user experience.

Most Common IaaS Security Issues and Ways To Mitigate Them

With today’s world of constant digitization, enterprises are continuously shifting their workload to the IaaS platform from the legacy infrastructure because of its speed and flexibility. Gartner expects IaaS to grow by nearly 13.4% to $50.4 billion by the start of 2021. However, as it is a cloud-driven concept, one cannot deny the presence of issues and security risks. The catch here is that just a single feature cannot provide complete security for the IaaS environment. It is so because the IaaS platform’s protection is a kind of shared responsibility, where customer security responsibilities involve ensuring cloud infrastructure is architected, deployed, and operated safely. The responsibilities also include maintaining the cloud security in aspects of firewalls, operating systems, data, platforms, etc. Whereas the providers have to secure the cloud in aspects like storage, global infrastructure, database, compute, etc.IaaS security issues are the most critical concerns for both users and providers alike, which need to be solved for high performance. Therefore, we present this blog to make the readers aware of the IaaS security issues. This will help in choosing a suitable solution for business data protection.Security issues in Infrastructure as a ServiceInfrastructure as a Service has some issues that must be resolved for high performance. These issues can be divided into two broader categories.Component wise security issues1. Service level agreement or SLA driven issues: SLA is the agreement between the client and the service provider concerning the quality of services and uptime guarantee. Enforcing the SLA and properly monitoring the SLA is one of the most common challenges one faces while maintaining trust between the provider and the client. The solution to this challenge is a Web Service Level Agreement (WSLA) framework, which is created to monitor and enforce the Service Oriented Architecture. WSLA maintains SLA trust by enabling third-party innovation to maintain the SLA provisions in cloud computing.2. Utility computing driven issues: Utility computing is known to be the commercial face of Grid and cluster computing, for which the users are charged per usage of services. The primary challenge involved with utility computing is its complexity; for instance, a service provider provides services to a 2nd provider, who also provides services to others. This makes it difficult to meter the services for the charges. The other challenging issue is that the whole system will become vulnerable to attackers who want to access services without paying. The answer to the first challenge is Amazon Devpay, which enables the provider at the 2nd level to meter the service usage and bill the consumer accordingly. The solution for the second challenge is that the service provider must keep the system clean from viruses and malware and keep the system risk-free. The system is also affected by the client’s practice; therefore, the client must keep the authentication keys safe.3. Cloud software-driven issues:Cloud software is the key that connects the cloud components to act as one single component. A cyber attacker has the power to attack against the XML services security protocols and attack the web services that can lead to a complete breakdown of the communication of services. The solution to mitigate these kinds of attacks is the XML signature for authentication and integrity protection. Another solution is XML Encryption that wraps the data in an encrypted manner, and that data needs to be decrypted to retrieve the original data.4. Networks driven issues: Internet connectivity and networking services play a critical role in delivering a service over the internet. There are issues in networks and internet connectivity, such as the “Man in the middle attack” – when an attacker manipulates the network connectivity by generating middle man access, from where the attacker can access all the classified permissions and data. The other type of such attack is known as the “flooding attack,” when an unauthorized user sends bulk requests to increase the chances of an attack due to those requests. The potential solutions can be like traffic encryption, which uses point-to-point protocols to encrypt the connectivity for avoiding the externals attacks. Another suitable solution can be continuous and efficient network monitoring on services to verify whether all networking parameters are running correctly or not. The externals attacks can also be avoided by implementing firewalls to protect the connectivity from outer attacks.Overall security issuesOverall security issues are judged on the basis of overall services rented by an IaaS provider. A few of these type of issues are as follows:1. Monitoring of data leakage and usage: All the data that is stored in the cloud must be kept confidential. It indicates that the providers and the clients must be aware of how the data is being accessed and ensure that only authorized users have access to the data. These issues can be solved by up-to-date data management services, which will continuously monitor the data usage and also restrict the usages as per security policies.2. Logging and reporting: Proper logging and reporting modules must be employed effectively to make the deployment of IaaS more efficient. Superior logging and reporting solutions can keep track of the whereabouts of the information, its user, the information about the machines handling it, and the storage area keeping it.3. Authorization and authentication:It is a well-known fact that just using a user name and password may not be enough for a highly secure authentication mechanism. It is the most common security measure a system has to maintain. A service provider must use multi-factor authentication to tackle this threat.Source : Security ChecklistConclusionThese are some of the risks and issues that must be resolved before deploying any service in the cloud. Superior monitoring of the resources must be done effectively to accomplish the quality of services and high performance from the providers. It is always better to enforce preventive measures before the matter goes out of hand. Industry authorities strongly recommended taking IaaS security as a serious concern. Although securing an IaaS environment is a challenge, the high level of control enables a customer to design and implement the security controls as per their requirements..filledCheckboxes input[type="checkbox"]{opacity:0;display :none;}.multiStepFormBody button.close{z-index:99;}

It’s CLOUDy out there!

“Cloud” or “Cloud Computing” has remained a buzz in the technology space for the last decade or so. But for a layman, what exactly does it mean? How does it affect or benefit us or any organization for that matter? What is the future like when it comes to the cloud?Also most importantly is it really worth all the hype?Let’s try to look into and answer as many concepts as possible here.Cloud Philosophy – Simplified:Firstly, to understand the cloud, we can take a simple example to relate to:Every family needs milk at home. The quantity of the milk needed per family may vary but is more or less constant for each of the family every day or on an average in a week. Now there could be scenarios or situations where one might have some guests visiting or some festivals in which the milk consumption may rise. Also, there could be scenarios where the family goes for a vacation, or some members of the family are out of time due to any reason during which the milk consumption for those many days would decrease. What does the family do during such days of upward spikes or a drop in requirement? They simply buy less milk or ask the milk vendor to deliver only the required quantity for the specified duration.So, the question here is “Would you by the cow, for your intermittently fluctuating milk requirements?” The answer is No!Now just to explain, consider the cow being “the cloud” which instead of milk gives us “resources” to order in the right quantity based on our needs at the given period. Simple, isn’t it? So we don’t spend huge amounts of our money in the infrastructure (cow). We can pay as per the use for the resources (milk) quite literally ‘milking’ the benefits of the cloud (cow).We all use the cloud:What if I told you that all of us used the Cloud even before we knew about it? Yes, we do.Consider you have word file saved on your desktop at the office and you need to access that file at home for further modification. Can you really just open up your computer at home and start working on the file? No, because that would be saved on your office computer hard-drive and you would have to either email it to yourself so that you can download it home for use or you would have to carry it in some pen drive.Now consider you were working on the same word file on some third party platform such as the Google Docs in your G-Drive. All you had to do was have an internet connection at home and sign-in into the G-Drive using the same account! That’s it.Basically, you accessed the Google Cloud where they had saved your file on their server. Same happens when you access your emails. Be it Google, Yahoo or Microsoft emails; these are never on ‘a particular computer’ but on the cloud or server. This makes it possible for us to log into any machine and simply check emails by signing in with our username and password. Cloud was never an alien concept; it’s just that it is more commercialized now and smaller businesses and startups who aren’t financially strong to have the infrastructure are now moving ahead to reap its benefits.Top Players in the Cloud :Now there are many organizations who have joined the ‘cloud party’ but the top contributors as per the latest 2018 survey are AWS (Amazon Web Services), Azure, Google & IBM. The following chart shows the market share of each of the player and how they compete with each other in terms of market adoption, Year on Year growth and footprints.Types of Clouds :Going further, there are various kinds of flavors in Cloud Computing that a business can choose to stick with. Depending on the need of the organization, a decision can be taken on whether an enterprise needs a Public, Private or Hybrid Cloud.Let’s briefly look at this in a bit detail.Public Cloud: This would be when an enterprise or business wants its resources to be available to everyone on the internet. The public cloud model allows users to utilize software that is hosted and managed by a third party and accessed through the internet, such as Google Drive. By allowing a third party to host and manage various aspects of computing, businesses can scale faster and save money on setup and management.Private Cloud: Private cloud infrastructure can be hosted in on-site data centers or by a third-party, but is managed by and accessible to the company alone. Companies can tailor private cloud infrastructure to meet the unique needs of the companies, specifically security and privacy needs. As opposed to the public cloud model, private clouds are not meant to be sold “as-a-service,” but is instead built and managed by each company, similar to a local or shared drive.Hybrid/Multi Cloud: This is just the combination of the private and public cloud. Here a company decided the nature of cloud services depending on resources and their access.Benefits of Cloud:Cost savings: The pay-as-you-go system also applies to the data storage space needed to service your stakeholders and clients. This means that you’ll get and pay for exactly as much space as you need.Security: For one thing, a cloud host’s full-time job is to carefully monitor security, which is significantly more efficient than a conventional in-house system. Because in the latter system, an organization must divide its efforts between a myriad of IT concerns, with security being only one of them.Flexibility: The cloud offers businesses more flexibility overall versus hosting on a local server. And, if you need extra bandwidth, a cloud-based service can meet that demand instantly, rather than undergoing a complex (and expensive) update to your IT infrastructure. This improved freedom and flexibility can make a significant difference to the overall efficiency of your organization.Mobility: Cloud computing allows mobile access to corporate data via smartphones and devices. This ensures everyone is updated considering over 2.6 billion smartphones being used globally today.Disaster recovery: Downtime in your services leads to lost productivity, revenue, and brand reputation. But while there may be no way for you to prevent or even anticipate the disasters that could potentially harm your organization, there is something you can do to help speed your recovery. Cloud-based services provide quick data recovery for all kinds of emergency scenarios from natural disasters to power outages. While 20 percent of cloud users claim disaster recovery in four hours or less, only 9 percent of non-cloud users could claim the same.Automatic software updates: For those who have a lot to get done, there isn’t anything more irritating than having to wait for a system update to be installed. Cloud-based applications automatically refresh and update themselves, instead of forcing an IT department to perform a manual organization-wide update.Competitive edge: While cloud computing is increasing in popularity, there are still those who prefer to keep everything local. That’s their choice, but doing so places them at a distinct disadvantage when competing with those who have the benefits of the cloud at their fingertips.My Experiences with Cloud :Talking of my own experience with cloud first-hand, I have a habit of maintaining and updating my own notes on the tasks I am performing. At the very early stages of my working career, I often maintained notes over some word files or notepad. But as the problem goes with traditional storage, accessing these notes irrespective of place and time was a hinderance. Then I soon realized that Microsoft’s OneNote was quite a solution to this problem. My notes got synced with the Microsoft Account and were accessible to me everywhere and anywhere I needed them. Later on, there were other apps such as Evernote that were synced with my mobile phone and offered me greater flexibility and control over my notes and data.Providing cloud-based storage users may be a small update form a company’ viewpoint; however, from the user perspective, this is a very significant change. It can alter the way you work and makes ones’ life far easier.I am also quite an avid reader, and I have a Kindle to satisfy my need to read. I also have a Kindle app on my mobile phone. Now if it weren’t for the cloud, I would have to carry either my mobile phone or Kindle to every possible place to maintain and continue the reading. But the Amazon Cloud syncs the Kindle application on the phone as well as the Kindle to a level such that I can pick up reading from where I left on my phone from Kindle and vice-versa. Basically the cloud synchronizes whatever I read on either of the devices to make life easier for me.Moreover, I have drafted and worked over this article as and when I could find time in the office, home or even while my commute in the bus! How was this possible? Yes, cloud.I worked on the MSWord online, and I could jot down my points, expand on them, add or edit them as something interesting struck my mind.Verdict:Cloud computing has been evolving the way businesses operate these days. Companies of all the shapes and sizes have been adapting to this new technology. Industry experts believe that cloud computing will continue to benefit the mid-sized and large companies in the coming few years.The Cloud is here to stay and the future is all “cloudy” (in a good way of course) with the growing needs and consumption of resources by Organizations and their clients. This is surely a way forward for also small businesses and individuals who also now need not worry about the price-overheads or infrastructure and just focus on the tasks.Also, it isn’t rocket science to understand that when businesses focus on the actual tasks to be performed rather than the overheads involved, they flourish.Data Sources:State of the Cloud 2018 ReportsSalesforce.com
