The Challenge

The client faced a challenge operating over 50 isolated VPCs with diverse EC2 workloads, creating fragmented infrastructure, operational complexity, and higher costs. The scattered environment hindered uniform security policies, resource optimization, and workload dependency management. Intel-based EC2 instances were costlier and less optimized than AMD alternatives, offering better price-to-performance ratios.

Solutions

• Design and implement a centralized multi-AZ VPC architecture using Terraform for consistent, repeatable deployments across the infrastructure.
• Consolidate EC2 workloads from 50+ isolated VPCs into the new secure VPC using automated migration workflows and comprehensive dependency mapping.
• Execute Intel-to-AMD migration strategy through benchmarking, in-place upgrades, and rebuild migrations to optimize cost and performance ratios.
• Establish seamless inter-VPC connectivity using AWS Transit Gateway and implement AMI replication strategies for smooth workload transitions.

The Results

AWS migration streamlined infrastructure from 50+ VPCs achieving 25% cost savings via AMD instances, enhanced operational efficiency through centralized architecture, boosted performance with optimized configurations, and ensured compliance through automated governance.
