Cloud bills climb when nobody owns idle disks, oversized nodes, and forgotten non-prod. FinOps starts with visibility and shared tagging—not a one-time discount purchase.
Rightsizing needs utilization data and owner context. Commitments (Savings Plans, Reservations, CUDs) come after you know steady-state demand.
Budget and anomaly alerts catch surprises early. Separate product cost from platform cost so conversations stay productive.
Savings that sacrifice reliability are not wins. Optimize with SRE in the room.
Set anomaly alerts on sudden spend spikes tied to services, not only account totals.
Review Kubernetes resource requests; request inflation is a quiet bill driver.
Revisit commitments when architecture changes—yesterday’s reservation can become today’s lock-in waste.
Key takeaways
- Visibility and tagging come before commitment discounts.
- Rightsizing needs utilization data plus an accountable owner.
- Optimize with reliability in the room—savings that cause outages are not wins.
FAQ
What should we cut first?
Idle disks, forgotten non-prod, unattached IPs, and obviously oversized always-on nodes with clear owners. Then tackle commitments on steady-state demand.
How do we keep FinOps from becoming blame?
Separate platform vs product cost, share budgets early, and celebrate durable reductions—not one-time spreadsheet theatre.
