A Windows desktop application is packaged for deployment to users’ Windows machines. The company acquired another organization whose employees primarily use Linux, and the company wants to rehost the Windows application on AWS with minimal development effort. All employees must authenticate before using the app, and the company uses on-premises Active Directory but wants simplified access management for AWS. Which solution rehosts the application on AWS with the least development work?

The correct solution leverages AppStream 2.0, which is designed for streaming desktop applications to any device, including Linux, with minimal re-engineering. Building an AppStream 2.0 image with the existing Windows application allows employees to access it via a web browser, eliminating the need for local installation or refactoring. AppStream 2.0 user pools simplify authentication and integrate with existing directories. Provisioning Amazon WorkSpaces would require a separate desktop for each user, which is less efficient for a single application and doesn't directly address the Linux user base without additional steps. Creating an Auto Scaling group of Windows EC2 instances with RDP access is a viable rehosting option but still requires RDP clients, which might not be ideal for Linux users, and managing domain joins adds complexity. Refactoring and containerizing the application is a significant development effort, contradicting the "least development work" requirement.
