COST 6. What access controls and procedures do you have in place to govern AWS usage?
Establish policies and mechanisms to make sure that appropriate costs are incurred while objectives are achieved. By employing a checks-and-balances approach through tagging and IAM controls, you can innovate without overspending.
Best practices:
 Establish groups and roles (Example: Dev/Test/Prod); use AWS governance mechanisms such as IAM to control who can spin up instances and resources in each group. (This applies to AWS services or third-party solutions.)
 Track project lifecycle Track, measure, and audit the life cycle of projects, teams, and environments to avoid using and paying for unnecessary resources.
