What is VDI (Virtual Desktop Infrastructure)?
VDI (Virtual Desktop Infrastructure) refers to the infrastructure environment that enables virtual desktops. A virtual desktop virtualizes the desktop environment of a client OS and runs it on a server. Users access the virtual desktop located on the server via their local device, exchanging screen display data and input information like keystrokes over the network to operate the virtualized client OS.
Client devices only need functionality to access the virtual desktop, enabling users to interact with Windows or other virtual desktops from devices running Android, iOS, or other mobile operating systems. This flexibility allows applications to remain unchanged while broadening the choice of endpoint OS. Additionally, centralizing applications and data on the server enhances security by reducing information leakage risks in cases where devices are lost. This makes virtual desktops increasingly popular for achieving flexible work styles and enhancing security. Virtual desktops are also used to run advanced graphical applications, such as virtualized GPUs powering 3D CAD or CAE solutions.
Efficient utilization of network bandwidth during screen data transfers is critical for an optimal virtual desktop experience. To meet this need, VDI providers offer highly efficient communication protocols. For example:
F5’s BIG-IP Access Policy Manager (APM) supports proxy functionalities for both PCoIP and Citrix ICA, enabling safe and fast virtual desktop usage.
