Virtual Desktop Infrastructure (VDI) is a system that allows users to access a virtual desktop from any device with an internet connection. It provides users with the convenience of accessing their own personal desktop from anywhere, anytime, without having to install and configure additional software on multiple devices. 

Essentially, VDI system allows for the remote management of operating systems, applications and data within a single infrastructure. The user’s personal virtual desktop can be accessed through client software such as Microsoft Remote Desktop Protocol or Citrix XenDesktop from any device, giving them complete mobility while they are away from their physical workstation. VDI also offers enhanced data security as all sensitive information remains in the secure cloud environment instead of being transferred between multiple devices on different networks.

Additionally, since all resources are centrally controlled in a cloud-based environment there is no need for hardware maintenance or upgrades which can result in substantial cost savings when compared to traditional desktops and laptops. Furthermore, with increased security requirements today most organisations have started to favour VDI due its high level of compliance capabilities – keeping endpoints free from viruses and malware while offering admins full control over OS and application patching cycles along with user authentication and access policies etc 

All this said however one must also keep certain factors such as network latency issues into consideration before fully switching to VDI as slow browsing speeds due to increased remote traffic can often render it unusable for many applications like video/audio streaming etc .
