Which AWS service provides instant access to applications with a responsive user experience on the device of your choice?

• A. AWS Amplify
• B. Amazon AppStream 2.0
• C. AWS IoT Core
• D. Amazon WorkSpaces

Answer: (B)

Delivering applications by streaming them from the cloud to the user’s device so the apps feel instantly available and responsive, without requiring local installation.

Amazon AppStream 2.0 is a fully managed application streaming service. It runs the apps in the cloud and streams them to any device, providing a smooth, responsive user experience while you don’t have to install the software locally. This makes it ideal for delivering single apps or a suite of applications to users on diverse devices (Chromebooks, iPads, Windows/Mac laptops, etc.) with on-demand access and scalable performance.

AWS Amplify focuses on building and hosting web and mobile apps, not streaming existing desktop apps. AWS IoT Core handles device connectivity and messaging for IoT, not delivering UI apps to endpoints. Amazon WorkSpaces provides full virtual desktops rather than streaming individual applications, which is a different use case.
