John accessed the corporate server from home using desktop virtualization. This technology enables users to run a desktop operating system and applications on a remote server or in a virtual environment while accessing it through a device such as a personal computer or a thin client. With desktop virtualization, the user experiences a virtual desktop interface that appears the same as if it were running locally, allowing for a consistent and secure experience regardless of location.

In this scenario, desktop virtualization allows John to securely connect to the corporate server and work as if he were physically present in the office. This is especially useful for remote work scenarios, providing access to essential applications and resources without requiring the user to be on-site. It also enhances security by keeping sensitive data on the server rather than on the potentially less secure remote device.

Other forms of virtualization, such as fabric, storage, or network virtualization, serve different purposes. Fabric virtualization focuses on managing resources within data center fabric networks, storage virtualization pools storage resources for easier management and provisioning, and network virtualization abstracts the network infrastructure to create virtual networks. None of these would be relevant to the context of John accessing a corporate server remotely in the same way that desktop virtualization is.
