Explanation

SSM Agent allows you to manage both on-premises VMs and EC2 instances from a single control plane in AWS Systems Manager. By installing the SSM Agent on all VMs, you can automate the software installation process across all instances using Run Command or Automation workflows. This approach scales easily and eliminates the need to manually log in to each VM or write custom scripts for different environments. AWS Config is a service that tracks the configuration of your AWS resources and can be extended to track on-premises resources via SSM. It can automatically detect any configuration drift (e.g., if the package gets removed or changed) and alert the system administrator in real- time. This ensures that any deviations from the desired configuration are flagged immediately, providing a continuous audit trail. Amazon SNS provides an efficient way to notify the system administrator whenever a configuration drift is detected. It integrates well with AWS Config and ensures that the appropriate personnel is notified promptly, ensuring rapid remediation. By using SSM Agent and AWS Config, you can automate package installation, continuously monitor for drift, and provide a fully auditable solution with minimal operational overhead.
