AWS cost optimization

AWS EC2 cost optimization

AWS EC2 is usually the largest line item on the AWS bill. Most teams pay 25-40% more than necessary because instance families, sizes and on/off schedules are not revisited after launch. TurboFinOps surfaces every EC2 oversize, idle and unattached state, then routes the fix through an approval gate.

Typical savings range$2,400-$18,000 / monthtypical observed mid-market AWS account with 80-300 EC2 instances

Waste signals

  • Instances stopped for 14+ days but still billed for attached storage
  • CPU utilization < 10% over a 14-day window
  • Dev / staging fleets running 24/7 with no schedule
  • On-demand workloads with no Spot or Savings Plan coverage
  • AMIs older than 90 days held by deregistered launch templates

Optimization levers

  • Rightsize from m5.2xlarge → m5.large where p95 CPU < 30%
  • Schedule dev/test fleets off nights and weekends (60-72% reduction)
  • Migrate stateless workloads to Graviton (typical 20% cost cut)
  • Adopt EC2 Spot for fault-tolerant tiers (up to 90% off on-demand)
  • Purchase a 1-year Compute Savings Plan covering steady-state baseline

Workflow

How TurboFinOps closes the loop

1. Scan

Connect read-only IAM role; TurboFinOps inventories every EC2 instance, AMI, EBS volume and elastic IP across all regions.

2. Surface

Findings flag idle, oversized, unattached and unscheduled resources with estimated monthly savings.

3. Approve

Each remediation passes conflict guard (IaC ownership tag, freeze window, change ticket) before any cloud API call.

4. Verify

Savings receipts at day 7, day 14 and day 30 confirm the bill actually dropped.

FAQ

Frequently asked questions

Does TurboFinOps need write access to stop or resize EC2 instances?+

No initially. The Free tier is read-only and surfaces findings. Write access is requested only when a fix is approved and the conflict guard passes.

How is rightsizing scored?+

Each candidate ships with p50 / p95 CPU and memory observations plus the recommended target family, so engineers see why a fix is suggested before approving it.

Will rightsizing break my IaC?+

IaC ownership tags are part of the conflict guard. If a resource is Terraform-managed, the remediation runs as a PR against the IaC repo instead of a live API call.
