Port forwarding sessions created using Session Manager, a capability of Amazon 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 Amazon 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 Amazon Command Line Interface (Amazon CLI).  

Session Manager is available in the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. To learn more about Session Manager, see the Session Manager documentation. For information about Amazon Systems Manager, see our product detail page
