A cloud cost audit and FinOps re-architecture

Auditing and re-architecting cloud spend for a growing SaaS company whose infrastructure bill was outpacing its user base, with no per-team cost visibility.

Illustrative impact based on published industry benchmarks — not results from a specific client.

The challenge

A growing SaaS company's cloud bill grew faster than its user base, and finance had no reliable way to attribute spend to product lines — idle and oversized resources were suspected but never actually measured.

Our approach

We implement tag-based cost allocation across every account, right-size EC2/RDS instances from real 30-day utilization data, move steady-state workloads onto Reserved Instances or Savings Plans, and enforce automated idle-resource cleanup via Terraform guardrails.

Expected impact

Flexera's 2024-2025 State of the Cloud research puts average cloud waste at 27% and found 84% of organizations call managing cloud spend their top cloud challenge — the two numbers this audit is built to move.

Flexera's State of the Cloud research has put average cloud waste in the high-20s percent range for several years running, and found 84% of organizations call managing cloud spend their top cloud challenge — while Gartner forecasts global public cloud spend climbing past $723B, meaning the absolute dollars at stake keep growing even as the waste percentage holds roughly steady.

Where the waste typically hides

Cloud waste rarely comes from one obvious culprit — it accumulates across idle dev/staging environments left running over weekends, oversized instances provisioned for a traffic spike that never repeated, and orphaned storage volumes nobody remembers attaching. The chart below shows a typical first-audit breakdown before cleanup.

Tagging before cutting

The audit starts with tagging, not cutting: every resource gets attributed to a team and product line before anything is resized or shut down, so the savings are durable rather than a one-time cleanup that drifts back within a quarter. Reserved Instances and Savings Plans absorb the predictable steady-state load; autoscaling and idle-resource guardrails, enforced via Terraform, handle the rest — the same infrastructure-as-code discipline behind our CI/CD modernization blueprint.

Frequently asked

Is 27% cloud waste a real, current figure?
Yes — Flexera's State of the Cloud research has put average cloud waste in the high-20s percent range for several consecutive years (27% in both the 2024 and 2025 reports), a stable, widely-cited industry figure, not an estimate we invented.
Will rightsizing break anything in production?
The audit works from 30 days of real utilization data before touching anything, and changes roll out gradually with monitoring in place — the goal is removing waste, not introducing new risk.
Do we need Kubernetes for this to apply?
No — tag-based cost allocation and rightsizing apply whether you're running EC2 instances directly, ECS, or EKS. The audit adapts to whatever compute model you're already running.
