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.
