AWS Cost Optimization: A FinOps Playbook

MRMarcus Reyes· Chief Technology Officer June 13, 2026 7 min read

AWS bills creep through a thousand small decisions. This is the FinOps sequence we run to reclaim 30–40% with no impact on availability.

Start with the boring wins

  • Delete orphaned EBS volumes, old snapshots, and idle load balancers
  • Right-size over-provisioned instances using utilisation data
  • Move steady workloads onto Savings Plans or Reserved Instances
  • Shift fault-tolerant batch jobs to Spot

Then optimise architecture

The bigger savings come from architecture: S3 lifecycle policies, Graviton migration, and serverless for bursty workloads.

FinOps isn't a cleanup. It's a monthly habit with an owner and a dashboard.
