Compute · 69 checks
Right-size and switch off what you're not using.
Compute is almost always the biggest line on a cloud bill, and the easiest to over-provision. Instances get launched for a test and never stopped; clusters are sized for a launch-day spike that never returns; functions linger long after the feature shipped.
Graymole inspects VMs (EC2, Compute Engine, Azure VMs), containers, serverless, and ML compute across AWS, GCP, and Azure, and pairs each finding with real utilization metrics, so you can tell genuine idle from quiet-but-needed.
Where the money is
- Idle and zombie instances are 100% waste, so stopping or terminating them is pure savings.
- Right-sizing oversized instances to a smaller class typically cuts 40–75% off that resource.
- Graviton (arm64) and Spot migrations cut compute rates 20–60% for the same work.
- Off-hours scheduling on non-prod fleets reclaims nights and weekends: about 65% of the week.
~75%
Right-sizing one always-on t3.2xlarge to a t3.large saves roughly 75% of its cost: about $1,800/yr on a single instance.
What we check
A representative sample: Compute has 69 checks in total across AWS, GCP, and Azure.
EC2 zombie instances
Instances doing nothing but still billing every hour.
EC2 low-CPU oversized
Right-size candidates backed by real CPU/memory metrics.
Azure VMs stopped but not deallocated
Stopped in the OS, still billing; deallocate to stop paying.
Vertex AI notebooks running 24/7
GCP ML notebooks left on around the clock for office-hours work.
Lambda Graviton (arm64) candidate
Switch functions to arm64 for ~20% lower cost, same code.
Lambda forgotten functions
Functions with no recent invocations still on provisioned concurrency.
ECS services with no traffic
Containers running 24/7 serving nobody.
EKS Spot capacity opportunity
Move fault-tolerant node groups to Spot for up to 70% off.
Auto Scaling minimum oversized
ASG floors set higher than demand ever needs.
SageMaker hosted endpoints low traffic
Expensive ML endpoints kept warm for trickle traffic.
