How should a large organization design a comprehensive cost governance strategy combining tagging, budgets, and Savings Plans across many accounts?
AdvancedAnswer
A comprehensive cost governance strategy typically enforces a consistent resource tagging policy across every account so spending can be accurately attributed to specific teams or projects, sets up AWS Budgets at both the organization and individual account level with alerts tied to relevant stakeholders, centrally purchases Savings Plans or Reserved Instances at the organization's management account level to maximize shared discount coverage, and regularly reviews Cost Explorer and Cost and Usage Report data to identify optimization opportunities and enforce accountability across teams.
