How We Cut an AWS Bill by 38% Without Touching Uptime

MRMarcus Reyes· Chief Technology Officer May 14, 2026 6 min read

Cloud bills creep. Not through one bad decision, but a thousand small ones. Here's the FinOps sequence we run that routinely reclaims 30–40% — with zero impact on availability.

Start with the boring wins

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

Then optimize architecture

Once the easy wins are banked, the bigger savings come from architecture: S3 lifecycle policies, Graviton migration, and replacing always-on services with serverless where bursty.

FinOps isn't a one-time cleanup. It's a discipline — a monthly habit with an owner and a dashboard.

The teams that sustain savings are the ones who make cost a first-class, visible metric — not a quarterly surprise.
