Cloud Cost Management & Optimization: Turning Visibility into Savings
The core loop
Optimization in Cloudability follows a repeatable loop: identify waste, quantify the opportunity, assign an owner, act, and verify the savings landed. The main levers are rightsizing (matching instance and service capacity to actual utilization), idle and orphaned resource cleanup (unattached storage, stopped instances still incurring storage, unused load balancers), commitment management (reserved instances and savings plans), and storage and network optimization (lifecycle policies, tiering, data transfer review).
Concepts to know cold
Understand utilization thresholds and why a resource below a coverage or utilization bar is a candidate, not an automatic action. Know commitment coverage (what share of eligible spend is covered by commitments) versus commitment utilization (how much of purchased commitments you actually consume). High coverage with low utilization means you over-bought; low coverage means you are exposed to on-demand rates. Know that savings plans offer flexibility across instance families and regions in exchange for commitment, while reserved instances are more rigid but can be deeper for specific shapes.
Traps
Questions often present a recommendation as guaranteed savings. Realized savings depend on action being taken and on the resource persisting. Another trap: treating a rightsizing recommendation as safe without checking performance headroom or burst patterns. Watch for confusion between potential and realized savings, and between coverage and utilization.
Worked example
Eligible compute spend is $100,000/month. Commitments cover $60,000, so coverage is 60%. Of the $60,000 committed, you consume $45,000, so utilization is 75%. The gap signals over-purchase relative to consumption; the uncovered $40,000 is your on-demand exposure. The decision is not "buy more" - it is to raise utilization before extending coverage.
