    • Users and policies can be used globally.
  • Users are given long-term credentials to access AWS resources (username/password or access keys).
  • Roles allow for short-term access to resources when assumed, using temporary access credentials.
  • IAM can work with Identity Federation such as Active Directory or Web Identity Federation (Facebook, Google, etc.)

  • CloudWatch can be used for monitoring, and CloudTrail can be used for logging account activity.
