Announcing the ability to enable AWS Systems Manager by default across all EC2 instances in an account
AWS Systems Manager customers now have the option to enable Systems Manager, and configure permissions for all EC2 instances in an account, with a single action using the Default Host Management Configuration (DHMC) Agent. This feature provides a method to help ensure core Systems Manager capabilities such as Patch Manager, Session Manager, and Inventory are available for all new and existing instances in an account. DHMC is ideal for all EC2 users, and offers a simple, scalable process to standardize the availability of System Manager tools for users who manage a large number of instances.
