Is Docker a virtualization tool?
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.

What is VDI computer?
Virtual desktop infrastructure (VDI) is a technology that refers to the use of virtual machines to provide and manage virtual desktops. VDI hosts desktop environments on a centralized server and deploys them to end-users on request.
What happens when a server is virtualized?
Server virtualization is the process of restructuring a single server into multiple small, isolated virtual servers. This process does not require new or additional servers; instead, virtualization software or hardware takes the existing server and partitions it into several isolated virtual servers.
