An IT administrator needs to consolidate several underutilized physical servers onto a single, more powerful machine. Each of the original servers runs a different operating system, and all applications must remain isolated from one another for security reasons. Which of the following technologies should the administrator implement to achieve this goal?
Virtualization is the correct answer because it refers to the creation of virtual versions of physical components, such as servers, where each virtual server, known as a virtual machine, operates in an isolated environment on the same hardware. The scenario describes a classic use case for virtualization, known as server consolidation, where multiple servers, potentially with different operating systems, are run on a single piece of physical hardware. Containerization involves encapsulating an application and its dependencies into a container, but it shares the host operating system's kernel and is not suitable for running different operating systems on the same machine. Serverless computing abstracts the server layer, with the cloud provider dynamically managing the allocation of machine resources, which is not what the administrator is trying to implement. High availability refers to systems that are designed to operate continuously without failure for a long period of time, but it is a design principle, not the specific technology used for running multiple operating systems on the same hardware.
