Engineering intent

Add operational economics and reusable environment structure without allowing cost tooling to mutate workloads automatically.

Architecture delta

  • OpenCost connected to the in-cluster Prometheus design
  • tested monthly node run-rate recording rule and USD 150 lab warning
  • VPA recommender-only mode (updateMode: Off)
  • read-only right-sizing report helper
  • VPC/EKS extracted into a reusable Terraform platform module
  • independent environment state/configuration retained
  • active/passive multi-region DR ADR with explicit activation criteria
  • dedicated Cost & Operations CI

Evidence

OpenCost/VPA chart rendering, cost-rule syntax and behavior tests, manifests and helper tooling are exercised by Cost & Operations CI. See Engineering Evidence.

Evidence boundary

The USD 150 alert is a lab node run-rate threshold, not a total AWS budget. This release did not claim real OpenCost allocation data, VPA recommendations or a tested regional failover.
