VDI servers can be set up on-site or in the cloud. In order to comply with security or regulatory requirements or for their own governance needs, organizations may have chosen on-premises VDI. This necessitates that the IT department of an enterprise manage the VMs that enable VDI as well as the underlying infrastructure, which would require ongoing maintenance and replacement once its useful life was up.
Cloud desktops, on the other hand, require no such investment or maintenance, just a regular, monthly payment. In order for the on-premises infrastructure to be able to support the expected number of concurrent users, significant investments are necessary in terms of hardware, such as servers, storage, and network bandwidth, and this will enable the infrastructure to support the expected number of concurrent users.
It is important to note that cloud desktops make it easier for end users to manage their own accounts, create directories, control applications, run administrative tools, and add applets and gadgets to their hosted desktop with less administrative overhead.
