Notes on cloud cost optimization and AI governance.
Spot capacity can cut compute costs by 60–90%, but only if your workloads are built to survive interruptions. Here is how to capture the savings safely.

Engineers control cloud spend but rarely see it. Give teams their own numbers, celebrate savings like features, and never use cost as a weapon.

Nothing on your bill is labelled "wasted". Idle capacity looks identical to useful capacity — until you measure utilisation instead of provisioning.
