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 Default Host Management Configuration (DHMC). 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.

DHMC also simplifies the experience of managing access to EC2 instances by attaching permissions at the account level, and removing the requirement to alter existing instance profile roles to enable Systems Manager. You can begin utilizing the benefits of DHMC in just a few clicks from the Fleet Manager console. 

This feature is available in all commercial and AWS GovCloud (US) Regions, excluding the China (Beijing) region, operated by Sinnet, and the Amazon Web Services China (Ningxia) region, operated by NWCD. To start using DHMC today, please see the product pages.
