The cost toolbox

AWS Cost Explorer

Visualize and analyze past and current spend with charts, filters, and 12-month forecasts. "Which service cost the most last quarter?"

AWS Budgets

Set thresholds and get alerts (or trigger actions) when actual or forecasted cost/usage exceeds them. "Email me if we're on track to exceed $1,000."

AWS Cost and Usage Report (CUR)

The most detailed raw billing data, delivered to S3 for analysis in Athena/QuickSight.

Cost allocation tags

Key-value labels (e.g., project:alpha) that let you break down the bill by team, project, or environment.

AWS Compute Optimizer

ML-based right-sizing recommendations for EC2, EBS, and Lambda.

AWS Billing Conductor / Billing console

The billing console shows invoices, payment methods, and the free-tier usage tracker.

Exam tip

Match the verb: analyze/visualize past costs → Cost Explorer; alert on future overspend → Budgets; most granular data → CUR; split costs by department → cost allocation tags; right-size instances → Compute Optimizer (or Trusted Advisor's cost checks).

Think of it like this

Cost Explorer is your bank statement with charts. Budgets is the text alert when your balance runs low. The CUR is the itemized receipt for every penny. Tags are writing a project name on every receipt so accounting can sort them.
