The Challenge
The platform ran on a fleet of hand-configured VMs in a single AWS region. Deploys took 45 minutes, required a specific engineer, and a regional outage would have meant a multi-day recovery. The team needed to migrate to modern, IaC-managed infrastructure without pausing feature development.

Engineering Approach
[01]
Audited the existing architecture and built a dependency map of every service.
[02]
Designed a multi-region AWS landing zone with Terraform from day one.
[03]
Built a CI/CD pipeline with progressive delivery so early migrated services could be validated safely.
[04]
Migrated services incrementally over 10 weeks, each with a tested rollback path.
Business Results
Deploy time dropped from 45 minutes to under 9 minutes.
Infrastructure is fully codified in Terraform now; nobody hand-configures a VM anymore.
Multi-region failover tested and validated; RTO reduced from days to minutes.
Monthly cloud spend reduced by 35% through right-sizing and reserved capacity.
“They migrated infrastructure that had accumulated for six years without a single incident, while we kept shipping features the whole time. That's the part that impressed our board.”
Stop guessing.
Start shipping.
