Virtualization has a number of benefits for service providers and people who run data centers:
Resource Efficiency: Before virtualization, each application server needed its own dedicated physical CPU. This meant that IT staff had to buy and set up a separate server for each application they wanted to run. (IT preferred one program and one operating system (OS) per computer because it made the computers more reliable.) Each physical server would always be used less than it could.
Easier Management: When software-defined virtual machines (VMs) replace physical computers, it's easier to use and manage policies that are written in software. This lets you set up automated workflows for IT service management. For example, administrators can define groups of virtual machines and applications as services in software templates with the help of tools that automate deployment and configuration. This means that they can install these services repeatedly without having to go through a complicated, time-consuming, and likely error-prone manual setup process each time. Based on the role of the virtual machine, admins can use virtualization security policies to make sure that specific security settings are in place. Policies can even save space and computing power by turning off virtual machines that aren't being used.
Minimal Downtime: OS and application crashes can cause downtime and make it hard for users to get work done. Administrators can run multiple redundant virtual machines next to each other and switch between them when problems happen. It costs more to run multiple redundant physical servers.
Faster Provisioning: It takes time to buy, install, and set up hardware for each application. If the hardware is already in place, it is much faster to set up virtual machines to run all of your applications. You can even use management software to make it happen automatically and add it to your existing workflows
