VDI: Virtualized Desktop Infrastructure

Virtual desktop infrastructure (VDI) is a virtualization technology that allows a desktop operating system (OS) to be hosted within the data center on a single, centralized server. VDI, a variation of server-based computing, or the client-server computing model, which is an application-based architecture for workload distribution. The key difference is that VDI offers total virtualization of the server without the use of an “as a service” platform.

The difference between persistent and nonpersistent VDI

Persistent VDI allows individual desktop users to view unique, customizable desktop images, and gives workers the ability to save any customized features for use later, even after logging out. Conversely, nonpersistent VDI offers only uniformly configured desktop images within the same pool on the data center server, and these desktops always revert to their original configuration upon each user logout. Obviously, persistent VDI sounds more modernized and convenient, but some ventures simply don't want their workers to have the ability to customize their desktops. Entities like call centers, online customer service providers, and desktops used within the healthcare industry are a few examples where nonpersistent VDI may be preferable to the business owner or manager.

VDI advantages

VDI offers some other interesting advantages, chief among these being the ability to salvage otherwise obsolete desktop computers by repurposing them as the clients of VDI. This works well because what is viewed on the screen is an image generated from the data center server, making older personal computers (PCs) with archaic CPU guts usable once again. Another advantage of VDI is that it removes the dangers of housing data and other information on a hard disk drive (HDD) by housing those items on the VDI within the data center. This can be a priceless feature for businesses that experience an outage, hack, or other type of failure. Because VDI allows end-users to access any file, folder, application, or software directly from the centralized server using a different or new desktop machine.

Why VDI should be built on the currency of cloud

The biggest computing companies have gone from client-server computing to VDI because it allows multiple users to run numerous applications locally across global enterprise infrastructures. But, for VDI to work at its highest potential, desktops ought to be isolated into their own lanes rather than sharing one pool of space within a virtualized data center server.

Interestingly, even though VDI is mostly thought of as a cutting-edge technology, most entities that use it are running VDI on logical unit numbers (LUNs) and volumes, which are not the currency of cloud. For enhanced speed, reduced latency, and ease of scalability, consider a VDI built on virtual machines (VMs): the authentic currency of cloud. VDIs built with desktop isolation by using VMs allow your desktop users to keep up with workloads, enjoy faster deployments, and lightning speed when spinning up or tearing down applications.

Tintri VDI on all-flash and hybrid storage

Utilizing tight integration through VMware Horizon (with View) and Citrix XenDesktop, the Tintri EC6000 Series All-Flash Array guarantees VDI performance through management at the VM level, for ease of use, enhanced productivity, and predictable outcomes at the server and desktop levels of the infrastructure and environment. Isolating desktops by way of VMs eliminates input/output (I/O) storms and noisy neighbors. It also allows your enterprise to mix desktop and server workloads on the same VMstore—with zero conflict between machines, or between machine and server.

Tintri VDI on all-flash or hybrid storage allows workers to focus on the tasks at hand without having to have data scientist-level understanding of VDI, computing, servers, cloud, or virtualization. With an easy-to-use interface that deploys desktop images from a VM-run VDI, workers can customize, save, find, deploy, and get their jobs done simply and more quickly.
