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 application streaming service that allows users to run applications on AWS and stream them to any device, including lightweight laptops. This enables students to access the application without requiring high-end hardware, as the processing occurs on AWS servers.

AWS AppSync is a managed service that simplifies application development by enabling developers to create GraphQL APIs. It does not provide application streaming capabilities or address hardware requirements for running applications.

Amazon WorkLink is a service that enables secure access to internal websites and web applications from mobile devices. It does not stream applications or alleviate the hardware requirements for resource-intensive applications.

AWS Elastic Beanstalk is a platform-as-a-service (PaaS) that allows developers to deploy and manage applications without worrying about the underlying infrastructure. However, it does not provide a solution for streaming applications to lightweight devices, and the hardware requirements of the application would still need to be met by the clients.
