Systems Manager Architecture


How it Works

  • Using AWS CLI/Console/SDK users can navigate to Systems Manger.
  • System Manager Performs operations of Ec2 Linux or Windows Instances.
  • During this process it interacts with other AWS Services such as
    • S3
    • Cloudwatch
    • CloudTrail
  • So, to give permissions for one AWS service to interact/access other AWS Services , we need to create a role.
