Source: AWS AWS Systems Manager enables you to manage large hybrid environments through an advanced on-premises instance management tier. With this launch, the advanced tier is now available in AWS China (Beijing) Region operated by Sinnet, and AWS China (Ningxia) Region operated by NWCD. The advanced tier enables you to manage hybrid environments with over 1,000 instances. The advanced tier also enables advanced functionality, such as using interactive shell access with Systems Manager Session Manager to connect to on-premises instances. Session Manager removes the need to open inbound ports, manage SSH keys, or use bastion hosts.
