40% Lower Infrastructure Costs with AWS RDS Migration

The client was facing challenges with outdated infrastructure and needed a cost-optimized solution without any upfront investment. Requirements included migrating data to encrypted storage accessible via on-premises virtual servers, using MariaDB due to application restrictions. Aziro set up IAM-restricted EC2 instances, configured a Site-to-Site VPN for secure connectivity, and implemented a Galera cluster to synchronize the MariaDB database, migrating data and databases using Rsync in the background.

The client's outdated on-premises infrastructure with limited cost optimization and required a solution without upfront investment. Application restrictions requiring MariaDB, combined with the need for encrypted storage accessible from on-premises virtual servers, added complexity to the migration approach and increased the importance of secure, reliable connectivity.

• High Upfront Infrastructure Costs: Outdated on-premises infrastructure requires a cost-optimized solution without any upfront investment, limiting flexibility in how the client could scale.

• Application-Driven Database Constraints: Application restrictions required a MariaDB-based solution, limiting database platform choices and adding complexity to the migration architecture.

• Secure Storage Requirements: Migrating data to encrypted storage accessible via on-premises virtual servers requires careful configuration of secure connectivity and access controls. 

Aziro understood the client's cost and security concerns and designed a migration architecture built around IAM-restricted EC2 instances and encrypted S3 storage. Secure Site-to-Site VPN connectivity linked on-premises infrastructure to AWS, while a Galera cluster setup ensured reliable database synchronization throughout the migration.

• IAM-Restricted EC2 Setup: Set up an EC2 instance in AWS with IAM restrictions, addressing client concerns around access control and infrastructure security requirements.

• Site-to-Site VPN Connectivity: Configured a Site-to-Site VPN to secure the connection between on-premises servers and encrypted S3 buckets driven by EC2 instances.

• Galera Cluster Synchronization: Implemented a Galera cluster setup for MariaDB, using Rsync in the background to synchronize data and database migration.

• AWS EC2 Instances
• AWS S3 Buckets (Encrypted Storage)
• IPSec Site-to-Site VPN
• Rsync (File Migration)
• Galera Cluster (Database Syncing)
• MariaDB / AWS RDS  

The migration delivered measurable improvements in infrastructure cost, security, and long-term scalability. Secure VPN connectivity and Galera-based synchronization ensured reliable database migration, while Aziro's recommendation to adopt AWS RDS positioned the client for greater affordability and reliability going forward.

• 40% Lower Infrastructure Costs: Recommended AWS RDS over on-premises services as a more affordable, reliable, and scalable alternative for long-term database management.

• Zero Upfront Investment Required: Delivered a cost-optimized infrastructure solution without any upfront costing, aligning with the client's budget and financial planning constraints.

• 100% Encrypted Data Storage: Migrated data to encrypted S3 storage accessible via on-premises virtual servers, strengthening data security and compliance posture.

• 2x Improved Database Reliability: Galera cluster synchronization and Site-to-Site VPN connectivity improved database reliability and scalability compared to prior on-premises setup. 

Aziro helps organizations modernize outdated database infrastructure without requiring significant upfront investment. Our teams design secure migration architectures using IAM-restricted compute instances, encrypted storage, and Site-to-Site VPN connectivity, ensuring data remains protected throughout the transition. From Galera cluster synchronization to Rsync-based file migration, we build reliable pipelines that respect application-specific constraints like database platform requirements.

Beyond migration execution, Aziro provides strategic guidance on long-term infrastructure decisions, such as recommending managed services like AWS RDS when they offer better affordability, reliability, and scalability. Whether you're navigating application restrictions or seeking a lower-cost path to the cloud, Aziro delivers migration strategies that balance security, performance, and cost efficiency.
