In today’s digital age, businesses of all sizes are looking for ways to streamline their IT infrastructure and reduce costs. One way to do this is through server virtualization. By using virtualization software, businesses can run multiple virtual servers on a single physical server, leading to increased efficiency and cost savings.

What is Server Virtualization?

Server virtualization is the process of creating virtual versions of physical servers. These virtual servers are then able to run their own operating systems and applications, as if they were physical servers. This is achieved through the use of virtualization software, which partitions a physical server into multiple virtual servers.

Benefits of Server Virtualization

There are many benefits to using server virtualization software, including:

Types of Server Virtualization
