Micro-Services and Containers – Overview and Benefits

The worldwide technology community is acutely focused on the Digital Transformation Era of the day. This focus has spiked an unprecedented demand in highly competent Digital Transformation Services from IT service providers. This article gives you an in-depth understanding of some key application containerization best practices, which will give you a clear perspective on the basic requirement for any robust Digital Transformation services and solutions. A Precursor On Digital Transformation And Containerization Digital transformation and containerization; let us see how two seemingly orthogonal ideas concur. Just as a precursor, we see people everywhere glued to their screens. People are experiencing and interacting with the world through the screens of their gadgets. In many countries, over 90 percent of people have access to and are using mobile phones, tabs, laptops, and other smart screen devices. The digital world is providing people with open, fast, and transparent access to the services and products. With so many people on highly available digital fabric, with digital identities, it has become imperative for businesses to provide services in the digital world. This drives digital transformation. Thus, we have witnessed rise in the container service providers globally. Since 2013, the growth & adoption of container technologies has been exponential and continues to explode with no hint of slowing down. CET (Cloud-Enabling technologies) which includes Virtualization, Containers, and Private PaaS is expected to grow at a CAGR of 8.84 percent during the period 2017-2021. Containers market hold a significant portion of market revenue, which promotes the upward revenue growth trajectory, given some of the adoption trends. With over $40B revenue projections for the year 2020, the adoption of containers has become a prime focus area for enterprise customers. Let us glance at the digital transformation journey with application containerization. Today’s Challenges With the advent of e-commerce and other web-applications, users have the following expectations from the service: The service should always be ON – up and running It should be accessible from anywhere It must be responsive (reasonably fast) It should work seamlessly with different form factors (screen sizes) without any change in user experience Ever changing technological landscape is varying at a rapid pace. New technologies, new competitors emerge quickly. Responding to these challenges needs agility. Along with the changes in technology, there are changes in compliance, rules, and regulations. This puts additional pressure on businesses to respond quickly. Most companies have monolith applications or set of such applications that are currently servicing the customers. Such applications run as a significant process consuming many resources. Although at times monolith applications give a good performance, they suffer from drawbacks such as: Lack Of Agility Increased Costs Less Flexibility Or Adaptability Lack Of Elasticity Transitioning To Micro-Services Before we jump into transitioning to micro-services, let us understand that micro-services is an architectural style that structures an application as a collection of loosely coupled small services, which implement business capabilities. The micro-service architecture enables the continuous delivery/deployment of large, complex applications. In other words, micro-services architectural style is an approach to developing a single application as a suite of small autonomous services, each running in its own process and communicating with lightweight mechanisms, often an HTTP(S) resource API, which is modeled around a business domain. Some of the benefits of micro-services include: 1. Likely to consume fewer resources Unlike monolithic applications, only those micro-services, that see demand, need to be scaled. In monolith applications, most of the modules have to be scaled up. Because few services may have to be scaled up, fewer resources are likely to be consumed most of the time. 2. Scalable yet elastic Micro-services can be scaled out as the need be. Over a server farm, micro-services could be scaled out. When there is drop in demand, those services could be turned off or reduced. Due to smaller footprint, more services could be accommodated. If not all the services see demand at the same time, a smaller set of resources could be used for more scalable and elastic services. 3. More adaptable Change in the business environment or rules and regulations make it necessary to tweak software. If policy engines were available as micro-service, other services do not get affected. Such micro-service could be separately updated or tweaked. It can be separately tested. Thus, micro-service based systems are more adaptable. 4. Isolation In most cases, changes in a micro-service do not affect other micro-services, provided there are well-designed interfaces between them. Thus, there is isolation between the services. Each service may use a different technology. Isolation reduces or eliminates the impact of technology or design choice. 4 Key Uses of Application Containerization ontainers provide a convenient way to implement micro-services. Virtualization is being used over last decade to achieve some of the goals discussed above and for better hardware utilization. Virtualization adds 30 percent overhead. Hypervisors that allow running virtual machines on hardware add to this significant overhead. Container overheads are minimal and can provide even better resource utilization. Containers run on a machine for most optimal performance and resource utilization. If the machine fails all the containers running on that machine, get impacted. Container orchestration & automation engine software such as Kubernetes address this single point of failure (SPOF). Deploying containers on server farms To handle a variety of failures and to provide always ON system, the containers must be deployed on a server farm. Software such as Kubernetes provides the ability to provide scalability, elasticity, load balancing of the containers over the farm. Containerization can help the digital transformation journey by creating a scalable, elastic, adaptable, and quick deployment of micro-services to align with the rapidly changing business needs. They can help to respond to disruptive technologies and rapidly changing business environment to meet today’s challenges.

Container World 2019: Key Tips, Planning and Takeaway

The much-awaited conference of cloud enthusiasts – Container World 2019 is just around the corner. Aziro (formerly MSys Technologies) will be attending the high profile event from April 17- 19 at the Santa Clara Convention center, California. Container World is a one of its kind conference focusing on the complete cloud-native ecosystem from the enterprise standpoint. It is the only vendor-neutral event to delve into strategic business questions, and technical intricacies of rolling containers into production. Container World 2019 specifically focusses on the disruption cloud-native technologies bring to enterprise IT.Attending Container World is an excellent opportunity to network and learn about best practices and advice from your peers and competitors.LocationThe Santa Clara Convention Center is approachable by three airports viz., San Jose International Airport (5.4 miles), San Francisco International Airport (31 miles), and Oakland International Airport (33.1 miles). In case you haven’t zeroed in on your travel plans yet, you need to make a move. Right now!The event attracts thousands of engineers and business leaders, and so last minute travel plans would leave you in a lurch. The official Santa Clara Convention Center website has a list of featured hotels that you pick to stay. You may want to choose one which is within a mile’s walking distance, as that will save you time (and money) to travel to the venue for the three days. You can consider using some of the available public transportation options to make travel simpler.Preparation and PackingPacking for any trip can be overwhelming for some. It always helps to create a to-pack list before you get to it. This is especially essential if you’re a first timer to Container World. As with most conferences, you will need to pack clothes that are suited for a business environment. However, events like this tend to be lighter and do not stress on strict business formals. You can aim for business casuals, with maybe a suit added in (for after hours). As for footwear, trust us, do not wear anything new, uncomfortable or anything too casual. This is because you would be on your feet most of the time during these three days.Some of the other packing essentials are:Business CardsGadgets- phones, laptops, tabs.ChargersAdaptersBattery packsIdentification CardsFlight information / ticketHotel informationListen to the KeynotesThe keynotes of Container World offer some of the “key” data and information that you’ll want to know. This is where noted experts set the underlying tone and summarize the core message of the convention. Container World has lined up some of the best names in Container and related technology practices to deliver these sessions. It is advisable to pack a note-taking kit or laptop whichever is feasible to take notes here.A brief Q&A round succeeds every key session. This is probably one of the rare opportunities to get your questions answered by the leaders of the industry- we’d recommend you go prepared beforehand with some questions. The keynotes are always a packed house, with techies scrambling to get the best seats in the house. So if you want to sit anywhere near the front, get there early.Network with PeersIt’s not every day you get to attend a tech “fest” like this. Your peers from around the world, with some of the legends whose work you follow closely, in the same room at the same time, is nothing less than a big party, trust us. Talk to the person on the next seat in between sessions and find out what drove him or her to be here. Walk up to a group of fellow attendees over lunch and see what they think of the sessions. Connect with them through the social accounts to make your impression last that much longer in their minds.You can also connect with people through Twitter and LinkedIn. Use hashtags that are relevant to the event to find out what others are sharing. Some key hashtags that you can use are:#ContainerWorld#ContainerWorld2019#ContainerWorld19If you want to connect with one of our reps, you can tweet using #MSysatContainerWorldIf you find someone really interesting, you can even ask for their phone number and ask them about the next event they will be attending. So fewer strangers for you to deal with 😉Follow UpOnce you’re back from the conference, send a follow-up email within a day or two to the people you met and any potential collaborators. To help the person remember you, make a mention of the conversation you had, for example: “I enjoyed talking to you after Wesley Chun’s keynote lecture at Container World.” Apart from emails, you can also stay in touch and further strengthen your professional relationship through LinkedIn.Set your out-of-office (OOO) autoreply messageAs you will be away for three business days plus traveling, you ought to set an out of office reply (or a delayed response reply) for your co-workers, clients or anyone who may want to get in touch with you during this time.
