Amazon WorkSpaces Applications improves multi-session fleet management

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 - including compute, memory and storage resources - and lowering the overall cost. This new drain mode capability helps administrators manage multi-session environments more seamlessly by preventing disruption to active users. When performing system maintenance, applying security patches, or scaling down resources, administrators can configure instances to gradually empty without abruptly terminating user sessions. This ensures users can complete their work smoothly while new connections are directed to other available instances, maintaining system stability and improving the overall end-user experience. This new feature is available at no additional cost in all [AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) where Amazon WorkSpaces Applications is available. Amazon WorkSpaces Applications offers pay-as-you-go pricing. For more information, see [Amazon WorkSpaces Applications Pricing](https://aws.amazon.com/appstream2/pricing/).
