Key Outcomes
- •60% improvement in scalability (resume claim)
- •Zero-downtime cutover to AWS (resume claim)
- •Lower infra cost with autoscaling and right-sizing
Context
A set of business-critical systems needed capacity headroom, reliability, and cost control—without an outage window.
Approach
- Blueprint & risk log (dependencies, data gravity, RTO/RPO).
- IaC with Terraform; progressive cutover via blue-green + DNS.
- Observability first: SLIs/SLOs, golden signals, error budgets.
- Perf & cost: autoscaling, right-sizing, storage tiers.
Results
- 60% ↑ scalability; zero downtime migration; lower monthly spend.
- Faster incident resolution with dashboards and alerts.
Lessons
- "Measure before move": bake in observability before flipping traffic.
- Progressive cutover beats big-bang.
