Step 2: Practice installing or updating SSM Agent on an instance - AWS Systems Manager

Step 2: Practice installing or updating SSM Agent on an instance

AWS Systems Manager Agent (SSM Agent) is Amazon software that can be installed and configured on an EC2 instance, an on-premises server, or a virtual machine (VM). SSM Agent makes it possible for Systems Manager to update, manage, and configure these resources. The agent processes requests from the Systems Manager service in the AWS Cloud, and then runs them as specified in the request. SSM Agent then sends status and execution information back to the Systems Manager service by using the Amazon Message Delivery Service (service prefix: ec2messages).

In this task, you install or update the SSM Agent on an Amazon Elastic Compute Cloud (Amazon EC2) instance.

Note

If you're working with your own on-premises servers or VMs, see the following topics:
