Since nothing is saved once the connection is terminated, IT does not have to maintain a large number of customized OS images, allowing for simplified datacenter management and reduced costs.Ī nonpersistent VDI implementation is well-suited for one-off access to a desktop, since it streamlines device management for kiosk and task workers who don’t need to save anything. In either case, no changes are saved upon restarting. The end client may be connected to the same desktop every time OR to a randomized one from the pool. In contrast, nonpersistent VDI works as follows: For users with complex and fast-paced digital workflows, this means they can easily pick up where they left off and benefit from extensive personalization of the desktop’s virtual apps and settings. Each subsequent time they access the VDI environment, they are connected to the same desktop with all of their changes retained in the virtual OS image-even after the connection is restarted. A user is assigned a standardized desktop from the resource pool the first time they log on. In contrast, nonpersistent VDI doesn’t save any changes. Under persistent VDI, a user always logs into the same desktop image, with all changes to applications and data retained for full personalization. 
Meanwhile, a hypervisor creates, runs, and manages the various host machine VMs that encapsulate individual virtual desktop environments.The connection broker-a software layer that acts as an intermediary between users and virtual resources-finds a virtual desktop within the resource pool for each client upon successful access of the VDI environment.End clients, such as PCs, tablets, or thin client terminals, must be constantly connected to the centrally managed server so they can maintain access to the virtualized desktops they’re hosting.
The virtual machines are host-based, meaning multiple instances of them can be housed on the same server within the datacenter.Each virtual desktop includes an operating system image, typically Microsoft Windows.Virtual desktops live within virtual machines on a centralized server.In all VDI deployments, the following characteristics apply: It also enables a consistent experience across multiple devices. In modern digital workspaces where numerous apps must be accessed on demand, VDI software facilitates secure and convenient remote access to help boost employee productivity.
