AVD: AVD is a cloud-based service from Microsoft that allows businesses to deliver virtualized desktops and applications to users, accessible from anywhere in the world, as long as they have an internet connection.

Terminology:

1. Host Pool: Host Pool is a collection of virtual machines (VMs) that provide virtual desktops or applications for users to connect to, either as shared or personalized desktops.

2. Application Groups: Application Groups in Azure Virtual Desktop are containers that organize and manage the apps and desktops that users can access.

There are two types:

RemoteApp: Allows users to access specific applications without the full desktop experience.

Desktop: Provides users with access to a full virtual desktop.

They help admins to assign and manage access to apps or desktops for different groups of users.

3. Workspace: Workspace in Azure Virtual Desktop provide users with a centralized access point to their virtual desktops and applications. Without Workspace, users wouldn’t have an easy way to find or launch the resources they needed. The Workspace organizes and simplifies the user experience by grouping all the assigned desktops and apps in one place, making access more efficient and streamlined.

Note: An application group can only be assigned to a single workspace.

4. Session Host: session hosts are the VMs that run the apps and desktops, and users interact with them based on how they’re set up—either shared or dedicated to them.

Difference between Host pool and Session Host:

Host Pool: The collection of VMs (session hosts) that users connect to.

Session Host: The individual VM that provides the desktop or application experience to a user.

In short, a Host pool is a container for multiple session hosts, and the session host is where the user’s virtual environment runs.
