Working with Session Manager
You can use the Amazon Systems Manager console, the Amazon Elastic Compute Cloud (Amazon EC2) console, or the Amazon Command Line Interface (Amazon CLI) to start sessions that connect you to the managed nodes your system administrator has granted you access to using Amazon Identity and Access Management (IAM) policies. Depending on your permissions, you can also view information about sessions, resume inactive sessions that haven't timed out, and end sessions. After a session is established, it is not affected by IAM role session duration. For information about limiting session duration with Session Manager, see Specify an idle session timeout value and Specify maximum session duration.
For more information about sessions, see What is a session?
