Virtual Desktop Interface
Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on the client/server computing model, sometimes referred to as server-based computing. For users, this means they can access their desktop from any location, without having to use a single client device. Since the resources are centralized, users moving between work locations can still access the same desktop environment with their applications and data. For IT administrators, this means a more centralized, efficient client environment that is easier to maintain and able to respond more quickly to the changing needs of the user and business.
Server Virtualization
Server virtualization is the masking of server resources, including the number and identity of individual physical server, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments.One common usage of this technology is in Web servers. Using virtual Web servers is a popular way to provide low-cost Web hosting services. Instead of requiring a separate computer for each Web server, dozens of virtual servers can co-reside on the same computer.There are several ways to create a virtual server, including virtual machine, operating system-level virtualization, and paravirtual machine.
