This article provides a comprehensive guide to automating the installation of the AWS Systems Manager (SSM) agent on unmanaged Amazon EC2 instances across multiple accounts and regions.

  • Requires specific prerequisites like supported operating systems, network connectivity, and package dependencies
  • Uses AWS CloudFormation to provision resources and Systems Manager Automation runbooks for agent installation
  • Deployment workflow includes three interconnected runbooks that validate, install, and report SSM agent status
  • Allows targeting instances using tags, specific accounts, or results from Diagnose and Remediate feature
  • Generates a comprehensive CSV report in S3 with instance-level details and execution logs
