Fundamentals of Virtualization:

What Is Virtualization?

Before we begin, we should have a basic understanding of what virtualization is. Here are three definitions from 3 of the industry’s top leaders when it comes to virtualization:

Microsoft’s definition of Virtualization: “Virtualization creates a simulated, or virtual, computing environment as opposed to a physical environment. Virtualization often includes computer-generated versions of hardware, operating systems, storage devices, and more. This allows organizations to partition a single physical computer or server into several virtual machines. Each virtual machine can then interact independently and run different operating systems or applications while sharing the resources of a single host machine.”

Amazon Web Services’ definition of Virtualization: “Virtualization is technology that you can use to create virtual representations of servers, storage, networks, and other physical machines. Virtual software mimics the functions of physical hardware to run multiple virtual machines simultaneously on a single physical machine. Businesses use virtualization to use their hardware resources efficiently and get greater returns from their investment. It also powers cloud computing services that help organizations manage infrastructure more efficiently.”

IBM’s definition of virtualization: “Virtualization is a process that allows for more efficient use of physical computer hardware and is the foundation of cloud computing.”

Why is virtualization important? (Evolving Needs of Businesses when it comes to virtualization)

Virtualization allows your business to be more productive and efficient without the need to go all in and invest in hardware and computing power that may not be needed for your operations. Virtualization allows your business to save money, use resources more efficiently and recover much faster from potential problems, should they arise. Let’s take a look at some of the benefits of virtualization

Benefits of Virtualization:

Cost savings: The use of multiple virtual servers can be very efficient for your business. It will allow you to save on the cost of hardware and energy consumption.

Reduce Downtime & Boost Business Continuity: Virtual machines can easily be backed up, and you can easily restore them to a saved version should you encounter a failure or downtime.

Improve efficiency and productivity: With virtualization, you can do more with less. Fewer servers need to be maintained, which means your tech team can focus more on important tasks rather than waste their time on tedious tasks such as patching, upgrading, and troubleshooting server hardware.

Better Allocation of Computing Resources: Virtualization allows you to streamline your operations and make better use of resources. It essentially means that you can run multiple virtual machines off a single computer, which means you can do more with much less.

For a deeper understanding of the basic fundamentals of this topic, take a look at IBM’s article on some of the benefits virtualization can bring to your organization.

Now that you have a better grasp of the fundamentals of Virtualization, let’s compare the 2 leading virtualization options available to you today: Proxmox and VMware.
