AWS Cost Explorer

Nov 5, 2022

• Aws

• AWS Wiki

• Capable of analyzing usage within the account, and giving recommendations about reserved instance purchases (if you have enough usage on the account)
• Cost Anomaly Detection: Help reduces cost with machine learning by tracking costs and usage
• Rightsizing Recommendations: Reviews historical EC2 usage to identify opportunities for greater cost and usage efficiency

• Cost allocation tags - have to be enabled individually
• (per account for standard accounts or ORG Master for ORGS)
• AWS Generated - e.g. aws:createdBy (details which identity created a resource, if already enabled) or aws:cloudformation:stack-name
• Added to resources AFTER they’re enabled by AWS, not retroactive
• User-defined tags can also be enabled user:something
• Both are visible in cost reports and can be used as a filter
• Can take up to 24 hours to be visible and active
