073 | Introduction to Virtualization: Why It’s Needed and How It Saves Time

August 4, 2025


What is Virtualization?

Virtualization is a technology that allows the creation of virtual versions of resources such as servers, operating systems, storage, or networks. It makes it possible to run multiple “virtual machines” (VMs) on a single physical server. Each VM operates as a fully independent computer with its own operating system and applications, while sharing the physical resources of the underlying hardware.

The key component of virtualization is the hypervisor. A hypervisor is software that creates and manages virtual machines, distributing the host machine’s physical resources (CPU time, RAM, disk space, and network interfaces) among them.
