What is Virtualization?

Virtualization is a mechanism that uses software to design an abstract virtual instance layer over the actual hardware. In other words, it means running multiple operating systems concurrently on a computer.

This process allows the machine’s hardware elements (memory, processors, storage, etc.) to be divided into multiple VMs (virtual machines). So, apps running on top of this virtualized layer will feel they have another dedicated machine to operate.

VM runs independently, although it runs on a small portion of the underlying computer hardware. Virtualization benefits enterprises by providing better computer hardware efficiency and enhancing the company’s hardware investment return.

Advantages of Virtualization

Efficient Management:
With software-based VMs, organizations can easily replace physical computers. As a result, using and handling pre-written policies in the software becomes easier and more efficient. You can also create automated IT service management frameworks.

Resource Efficiency: Before the advent of virtualization, every application on the computer required a dedicated physical CPU. IT staff would go through the hassle of purchasing and configuring a separate server for each app they wanted to use.

However, this meant that every physical server would stay underused. With server utilization, you can operate and run several apps, each with its dedicated VM and OS, on a single computer hardware without compromising the device’s reliability. As a result, maximum utilization of hardware is achieved.

Quick Provisioning: Purchasing, installing, and configuring hardware for each app can be time-consuming. However, the provision of virtual machines to run all the required apps is faster if the hardware is all in place. You can even automate the VM to use software in the existing workflows.

Minimal Downtime: Application and operating software crashes can cause a lot of downtime while disrupting users’ productivity levels. However, computer admins can run numerous redundant VMs concurrently and switch between them if and when problems arise. In contrast, running numerous redundant physical servers is far more expensive.
