Port forwarding sessions created using Session Manager now support multiple simultaneous connections
Port forwarding sessions created using Session Manager, a capability of AWS Systems Manager, now support multiple simultaneous connections over the session. This improvement reduces the rendering latency and improves load times for applications that load data using multiple concurrent connections, when delivering such applications over a port forwarding session.
To benefit from this improvement, install version 3.0.222.0 or later of the AWS Systems Manager Agent (SSM Agent) on the managed instance that you are establishing a port forwarding session with. Also, you must use version 1.2 or later of the Session Manager plugin for the AWS Command Line Interface (AWS CLI).
Session Manager is available in all AWS Regions where AWS Systems Manager is available. To learn more about Session Manager, see the Session Manager documentation. For information about AWS Systems Manager, see our product detail page.
