Container and capacity efficiency
Workload sizing and autoscaling behaviour were reviewed together so savings did not come from simply removing production headroom.

42% lower AWS spend—with releases moving 3× faster.
A growing payments platform needed to control cloud costs without trading away release speed. Anrotex connected infrastructure efficiency, database tuning, repeatable configuration, and safer delivery into one engineering programme.

The business constraint
Cost control could not become a delivery slowdown.
The platform was growing, and leadership needed the AWS bill to reflect that growth more efficiently. Engineering still needed room to release frequently and operate a production payments workload safely.
That ruled out a spreadsheet-only exercise. Each saving had to be connected to workload behaviour, release mechanics, and the configuration the client team would own after the engagement.
The programme treated reliability and engineering ownership as constraints, not as trade-offs to revisit after savings were found.
What changed
Four improvements working together.
Cost, performance, and release safety were reviewed together so one improvement did not create a hidden problem elsewhere.
RDS and caching
Database capacity and caching behaviour were tuned around actual workload needs rather than isolated service-level recommendations.
Infrastructure as Code
Terraform made the target configuration repeatable, reviewable, and easier for the client team to own after delivery.
Safer release flow
Blue-green delivery reduced release risk while removing the manual friction that had constrained deployment throughput.
Outcome
Lower run rate. Faster path to production.
AWS cloud spend was reduced by 42% for the engagement.
Release throughput improved by 3× after the delivery changes.
Terraform left the target infrastructure easier to review, reproduce, and transfer to the client team.
The result came from coordinated engineering changes rather than one isolated discount or commitment purchase.
