Which AWS services can the company use to meet these requirements?

Explanations:

Amazon Connect is a cloud-based contact center service and is not designed for providing managed virtual desktops or applications. It focuses on customer engagement and does not address the requirements of remote desktop access.

Amazon AppStream 2.0 is a fully managed application streaming service that allows organizations to deliver desktop applications to users securely over the internet. It fits the need for providing applications to remote employees.

Amazon WorkSpaces is a managed, secure Desktop-as-a-Service (DaaS) solution that provides Windows and Linux virtual desktops. It allows remote employees to access their desktops securely, fulfilling the requirement for managed virtual desktops.

AWS Site-to-Site VPN enables secure connections between on-premises networks and AWS, but it does not provide managed virtual desktops or applications. It can be part of a solution but is not a standalone service for desktop management.

Amazon Elastic Container Service (Amazon ECS) is a container orchestration service primarily for running containerized applications. It does not provide desktop environments or application streaming services needed for virtual desktop solutions.
