In Citrix, you'll use the Citrix Workspace app (formerly Citrix Receiver). The Workspace app is also available for Windows, macOS, iOS, Android, Linux, and Chrome. Further, each VDI solution has an agent that is installed inside every managed virtual desktop, physical system, or RDS host to allow it to be managed as a part of the VDI environment overall. The agent handles tasks such as printing, USB support, and more. Understanding the role of connection broker software Technically, you don't need anything except a simple client and RDP to connect to a Windows desktop running on a virtual host. However, for organizations of any size, the use of a connection broker to handle such activity is all but required. A connection broker helps a user's VDI client connect that user to an appropriate virtual machine instance. The broker handles the task of authenticating users as they attempt to connect. The broker also tracks which desktops a user should have access to. The connection broker may also make associations between assigned virtualized applications and a logged in user. The bro- ker handles responsibility for ensuring that any user policies are applied at login. In a Citrix environment, this service is handled by the Delivery Controller component. In a VMware Horizon environment, bro- kering is handled by the Horizon Connection Server. Considering other software components The previous section discusses components that are, more or less, required components in a VDI deployment. This section covers some additional components that you should consider. Connection protocols Connection protocols have a direct impact on the user experience, central processing unit (CPU) consumption on the host and end- point, and the battery life of mobile endpoints, such as smart- phones and tablet devices. If you're on a super-low latency and ultra-fast connection, you might be able to use a protocol that
