Virtual Desktop Infrastructure (VDI) is a technology that allows users to access a desktop environment hosted on a remote server. Instead of running applications and storing data on a local computer, users connect to a virtual machine that operates in a data center. This setup enables centralized management, security, and easier access to resources from various devices. VDI is beneficial for businesses as it simplifies IT management and enhances security. By keeping data on the server rather than individual devices, organizations can better protect sensitive information and ensure that software updates are consistently applied across all virtual desktops.
