AWS Cost Explorer
AWS Cost Explorer visualizes and analyzes historical and forecast AWS cost and usage. It helps teams understand service, account, tag, and usage-type drivers behind a GenAI architecture.
Key points
- Filters and groupings break down spend dimensions
- Forecasts extrapolate from available billing history
- Rightsizing and reservation recommendations apply only to supported resource types
When to use it
- Compare Bedrock and self-hosted inference cost trends
- Identify data transfer or log ingestion as an overlooked RAG expense
Exam tips
- Choose Cost Explorer for retrospective cost analysis and application metrics for per-request token economics
- Allocate shared costs with tags or cost categories before drawing workload conclusions
