Cloud cost optimization: prioritize billing evidence, not blind downsizing
Use billing and utilization evidence to identify actionable savings and operational risk.
Skills
Fix account, services, currency, and billing window. Load billing exports and resource-tag/utilization data and normalize them to the same period before explaining changes. Analyze idle capacity, overprovisioning, storage tiers, data transfer, and commitments separately. For each opportunity state baseline cost, estimated savings, confidence, service impact, and validation needed. Keep read-only recommendations separate from resource changes. Before deleting, downsizing, or buying a reservation, confirm ownership, dependencies, and recovery path and obtain approval. Treat savings as estimates and verify them with later bills.
Permissions
Prerequisites
- For analyzing cloud costs, tags, idle resources, and rightsizing across AWS/Azure/GCP/OCI.
- Specify accounts/projects and billing period; prefer read-only exports.
Permissions
- May read billing/resource data and recommend changes; deletion, downsizing, or commitments affect production/spend.
- Get confirmation before changes; low utilization alone does not prove a resource is disposable.
Limitations
Normalize currency/time windows, distinguish usage from commitments, and label savings as estimates.
