This pattern describes how to connect to an Amazon Elastic Compute Cloud (Amazon EC2) instance by using the Session Manager, a capability of AWS Systems Manager. Using this pattern, you can run bash commands on an EC2 instance through a web browser. Session Manager doesn’t require that you open inbound ports and doesn’t require public IP addresses for EC2 instances. Additionally, it removes the need to maintain bastion hosts with different Secure Shell (SSH) keys. You can govern access to Session Manager with AWS Identity and Access Management (IAM) policies and configure logging, which records important information, such as instance access and actions.
