AppStream 2.0: Fully managed secure application streaming service that allows a user to stream a desktop application from AWS to any device running a web browser without re-writing them.

For example, think about a secure application that you would need to install at the end user’s machine. With AppStream you would install the app on AWS and then stream the data on to any remote machine the user is on. This helps in centrally managing your applications and not having to install the app on end-user machines.

AWS Workspaces: It is a fully managed, serve desktop as a service (D-a-aS) that runs on AWS. You can provision virtual, cloud-based Microsoft Windows desktops for your users, providing them access to the documents, applications, and resources they need.
