70% cost reduction on QA environment
Challenge
The QA AWS environment in sa-east-1 was always-on and costly; cloud spend was hard to justify for non-production workloads.
Solution
We migrated the QA environment to us-east-1, switched to SPOT instances, and implemented startup/shutdown jobs for Kubernetes so clusters run only when needed.
Result
70% cost reduction with the same performance and availability. QA costs became predictable and aligned with actual usage.
