Amazon WorkSpaces Applications Drain Mode

Amazon WorkSpaces Applications now enables instances in multi-session fleets to stop accepting new user sessions, while allowing existing sessions to continue uninterrupted. This capability, known as drain mode, ensures seamless operations during maintenance, scaling, or system updates.

Multi-session fleets allow hosting multiple end user sessions on a single instance, helping to maximize usage of the underlying infrastructure and lowering the overall cost. This new drain mode capability helps administrators manage multi-session environments more seamlessly by preventing disruption to active users.

What to do

  • Configure instances to enter drain mode during system maintenance or scaling.
  • Direct new connections to other available instances to maintain system stability.
  • Ensure users can complete their work smoothly without abrupt terminations.

This new feature is available at no additional cost in all AWS Regions where Amazon WorkSpaces Applications is available.
