Which AWS service will help the company deploy the application without investing in backend infrastructure or high-end client hardware?

Explanations:

Amazon AppStream 2.0 is a fully managed service that allows the application to be streamed to low-cost, lightweight devices without needing high-end hardware.

AWS AppSync is used to build APIs with GraphQL for accessing data in real time, not for streaming applications to client devices.

Amazon WorkLink enables secure access to internal websites from mobile devices, not full application streaming.

AWS Elastic Beanstalk is a platform-as-a-service (PaaS) for deploying applications but does not address the need for high-end hardware on client devices.
