What uses desktop virtualization to separate the personal computing environment from the user's physical machine?

The concept that utilizes desktop virtualization to create a distinct personal computing environment from the user's physical machine is known as Virtual Desktop Infrastructure (VDI). VDI allows users to access a virtual desktop that is hosted on a remote server rather than relying solely on a local installation on their physical device. This separation enables users to work within a contained environment that can be managed and secured independently of their local system.

VDI offers several advantages, such as enhanced security, as sensitive data can be stored and processed on the centralized server instead of on the local device, reducing the risk of data loss or exposure. It also provides flexibility, as users can access their virtual desktops from various devices and locations, maintaining a consistent work environment regardless of hardware variations.

In contrast, the other options do not focus on desktop virtualization or the separation of computing environments. Security orchestration, automation, and response (SOAR) is primarily related to managing security processes, while autoscaling is a technique used in cloud computing for adjusting resources dynamically based on demand. Bootstrapping generally refers to the process of starting a system or application, often in a self-sufficient manner, but it does not pertain to virtual desktop environments.
