Explanation

Amazon WorkSpaces is the correct AWS service for providing remote access to virtual desktop computers from the internet.

Service Overview:

• Amazon WorkSpaces: A fully managed, secure Desktop-as-a-Service (DaaS) solution that allows users to access persistent, cloud-based virtual desktops
• Users can access their virtual desktops from various devices including laptops, tablets, and thin clients

Why the other options are incorrect:

• Amazon Connect: A cloud-based contact center service for customer service, not virtual desktops
• Amazon Cognito: A service for user authentication and authorization, not desktop virtualization
• Amazon AppStream 2.0: While this is also a desktop streaming service, it's designed for streaming desktop applications to web browsers, not providing full persistent virtual desktop infrastructure like WorkSpaces

Key Features of Amazon WorkSpaces:

• Persistent virtual desktops (users maintain their files and settings)
• Supports Windows and Linux desktops
• Secure access via encrypted connections
• Pay-as-you-go pricing model
• Integration with AWS Directory Service for user management

This makes Amazon WorkSpaces ideal for scenarios where users need full virtual desktop computers accessible remotely over the internet.
