Final answer:
Amazon AppStream 2.0 is the AWS service that allows desktop applications to be delivered and accessed via a web browser without requiring additional servers or infrastructure maintenance.
Step-by-step explanation:
A company looking to make its desktop applications available to employees through browsers on their devices/laptops without procuring servers or maintaining infrastructure would benefit from using Amazon AppStream 2.0. This AWS service allows for the delivery of desktop applications to any computer via a web browser, which means the clients do not need to install the apps on their devices and can access them from anywhere. The applications are streamed from AWS servers, which handle the infrastructure, scaling, and security. Amazon WorkSpaces is also a Desktop-as-a-Service solution that provides cloud-based virtual desktops, but it is not delivered via a standard web browser. Amazon Snowball is used for large-scale data transfer and Amazon Outposts is for hybrid cloud setups which don't meet the specified requirement.
