A SaaS company was paying for always-on virtual machines sized for imaginary peak load. Most sat nearly idle, and the finance team wanted to know why the cloud bill kept climbing.

The challenge

  • VMs sized for peak but running at 22% average utilization.
  • No autoscaling, so capacity didn’t track demand.
  • No committed-use discounts, so everything ran at on-demand rates.
  • No visibility into which instances were actually doing work.

What we built

  1. Utilization audit profiled every instance and workload to find what was real and what was waste.
  2. Right-sizing resized and consolidated instances to match actual demand.
  3. Autoscaling added instance groups that scale with load instead of sitting idle.
  4. Committed-use discounts locked in reservations for steady workloads, cutting rates sharply.
  5. Monitoring set up cost and utilization dashboards so drift gets caught early.

The results

Compute spend dropped 45%, from $6,800 to $3,740 a month, while utilization rose from 22% to 68%. Latency and throughput were unchanged; only the waste disappeared.

The takeaway

The cloud bill is a design decision, not a fact of life. Right-sizing plus reservations turns an idle fleet into a fraction of the cost.

We cut the compute bill almost in half and performance didn't budge. Finance finally stopped asking questions.
