AWS cost review field notes Heliodor | support@heliodor.cloud Review spending in a consistent order: establish the baseline, explain usage, identify changes and check their impact. This keeps a cost review connected to workload needs. ESTABLISH A BASELINE [ ] Select a representative time period and note seasonal demand. [ ] Record credits, tax, support fees and costs excluded from comparisons. [ ] Separate accounts, teams, products and shared platform costs. EXPLAIN CONSUMPTION [ ] Find the services, regions and usage types driving the largest changes. [ ] Check idle resources, resource schedules and storage retention. [ ] Review data transfer paths and logs before changing the architecture. ASSESS ACTIONS [ ] Validate rightsizing recommendations with utilisation and performance data. [ ] Estimate implementation effort and operational risk for each change. [ ] Assess commitments against stable usage, term and future demand. MEASURE & MAINTAIN [ ] Agree an owner and approval route for each optimisation. [ ] Compare the result with the baseline, accounting for demand changes. [ ] Review budget alerts and anomalies as part of a recurring routine. Share the key spending questions and a representative billing period. Avoid sending credentials or access keys by email.
