What Is Virtualization and High Availability
Virtualization is the fundamental technology that powers cloud computing. This software separates compute environments from physical infrastructures, so you can run multiple operating systems and applications simultaneously on the same machine.
One of the biggest benefits of virtualization is sever consolidation. Instead of maintaining multiple servers that each have a different function, server virtualization allows you to split the resources of a single server for multiple purposes. Often server resources are underutilized, resulting in businesses spending too much on server upkeep for a little output.

Virtualization uses software to create an abstraction layer over the physical hardware. In doing so, it creates a virtual compute system, known as virtual machines (VMs). This allows organizations to run multiple virtual computers, operating systems, and applications on a single physical server essentially partitioning it into multiple virtual servers. Simply put, one of the main advantages of virtualization is that it's a more efficient use of the physical computer hardware; this, in turn, provides a greater return on a company's investment.
Advantages Of Virtualization - Quick Recovery Time
When a disaster affects a physical server, someone is responsible for replacing or fixing it and this could take hours or even days. With a virtualized environment, it's easy to provision and deploy, allowing you to replicate or clone the virtual machine that has been affected. The recovery process would take mere minutes as opposed to the hours it would take to provision and set up a new physical server and significantly enhancing the resiliency of the environment and improving business continuity.
