Research and Engineering Studio on AWS Version 2025.12 now available

Today we announce Research and Engineering Studio (RES) on AWS version 2025.12, which introduces tag propagation for CloudFormation resources, enhanced Windows domain configuration options, default session scheduling, and security improvements.

Research and Engineering Studio on AWS is an open source solution that provides a web-based portal for administrators to create and manage secure cloud-based research and engineering environments. RES enables scientists and engineers to access powerful Windows and Linux virtual desktops with pre-installed applications and shared resources, without requiring cloud expertise.

Tags applied to the CloudFormation stack now propagate to all resources created during RES deployment, making it easier to track costs and manage resources across your organization. Administrators can disable automatic Windows domain joining for hosts, providing flexibility to implement custom domain-join logic when needed. You can now set a default schedule for all new desktop sessions, helping teams standardize session management practices. This version includes several security improvements to help RES deployments meet the NIST 800-223 standard and fixes a bug where some sessions were logged out after 2 minutes when using a custom DNS domain.

This release is available in all AWS Regions where RES is available. To learn more about RES 2025.12, including detailed release notes and deployment instructions, visit the Research and Engineering Studio documentation or check out the RES GitHub repository.
