To keep pace with today’s increasing storage and processing needs, many organizations must deploy multiple servers, each running on a fraction of their capacity. This leads to excessive operating costs and enormous inefficiencies. This is where virtualization comes in.
Virtualization software simulates hardware functions and creates a virtual computer system called a virtual machine (VM). A VM is an independent, tightly isolated software container with an operating system (OS) and an application in it.
Virtualization enables companies to run more than one VM and multiple operating systems and applications on a single server, resulting in greater efficiency and economies of scale. Virtualization software dynamically assigns hardware resources to each VM as needed. Essentially, virtualization allows you to use the full capacity of computer resources.
The most important properties of VMs include:
- Hardware independence
