Virtual desktop infrastructure is virtualization that is designed to contain a desktop OS on a virtualized server in a data center. The virtual instances of the operating systems and application are transmitted as snapshots to client machines.
The VDI uses two key approaches which are persistent and nonpersistent. With the persistent approach, every user has his or her own desktop image that can be personalized and saved to be used in the future, just like the ordinary physical desktop. Nonpersistent VDI offers numerous desktops that users can access any time. Non-persistent desktops relapse to their original state every time the operator signs out.
Advantages of VDI is desktop centralization approach whereby a desktop OS such as Microsoft windows operates and it is managed in a data environment. The desktop image is sent to a network connection to endpoint gadget that lets the operator interacting with the operating system and its application. The endpoint can either be a mobile gadget, a thin client or even a traditional PC.
This approach comes with numerous advantages, based on the kind Of VDI used. Since little actual computing occurs at the endpoint, the IT sectors will have a chance to prolong the life cycle of old computers by repurposing them as VDI clients. When the moment to acquire new devices comes, business will have to invest in less expensive and less powerful devices.
Since all the data is stored in the data environment and not on the endpoint, there are numerous security peaks of VDI. If a laptop that runs on a VDI lands on the wrong hands, the data is always secure since it is not stored in the computer.
Additionally, the nonpersistent VDI helps in the management of various tasks. In most cases, IT has just a few master images to secure and maintain which tend to be easy than managing a whole desktop for each operator.
