AWS migration & re-architecture

Infrastructure

Monolith to scalable AWS infrastructure. 99.9% uptime, 40% lower spend.

/ The Brief

The problem.

A revenue-critical monolith was buckling under traffic spikes, cloud bills were climbing without explanation, and on-call rotations had become a permanent fire drill.

Goals
  • Eliminate single-points-of-failure under production load.
  • Bring cloud spend under predictable, observable control.
  • Establish infrastructure as code from day one.

/ Our Approach

What we built.

We carved the monolith into well-bounded services on AWS, codified everything in Terraform, and installed observability and cost guardrails before we cut over a single workload.

  • 01Strangler-fig migration — services moved incrementally with zero downtime.
  • 02Multi-AZ, auto-scaling compute with infrastructure-level rate limiting.
  • 03Full Terraform IaC; every environment reproducible from main.
  • 04Cost dashboards, budgets, and right-sizing built into the CI pipeline.

/ The Result

Outcomes that shipped.

The platform now absorbs 5× peak traffic without paging anyone, and the finance team gets a unit-economics view instead of a surprise invoice.

“We stopped firefighting. The platform takes our worst days in stride, and we finally know what every dollar of cloud spend is buying us.”
