Cost Explorer Workflow
Explore the Cost Explorer workflow to identify and analyze AWS cost spikes effectively. Learn to narrow down costs by service, region, and usage type, verify cost drivers with operational signals, and implement safe, reversible changes to manage costs without impacting reliability.
The ones worth stopping for look like a weekly cost chart jumping sharply, and the only useful first question at that point is what changed and whether it was expected. Locking the investigation to a single time window that includes a stable baseline and the spike window comes first, with scope kept tight by selecting the linked accounts, Regions, and any environment tags the org already uses. If tags are missing, that gap is a limitation to work around, not a reason to guess which workload paid the bill.
The non-goal is optimizing everything. The goal is identifying the dominant cost driver and the safest next action, which usually means a reversible change or a verification step that cannot reduce reliability. When the driver is real usage growth, the next action might be capacity planning, not a configuration ...
