What is Virtualization and How and Why is it Used?
JohnVirtualization stands out as one of the most important elements of cloud computing technology. In cloud technology, programs can be accessed without installation. Virtualization is often known as Virtualization. In virtualization, you can break down physical resources to the extent you want. In this way, you can take the efficiency level of the servers to an ideal point. This process also saves you from a financial burden and labor loss.
A User-Friendly System
In virtualization, which offers users a great space of freedom, concrete devices evolve into an abstract state, as the name implies. Divided resources can be found on different computers after abstraction. Hardware parts include a hard disk, ram, and graphics card as an example. Besides, the software parts of the computer can be shared by abstraction. At this point, we can provide security programs or operating systems as examples.
Virtualization has been a savior especially for companies that actively play a role in digital platforms. In offices, laboratory environments or educational institutions, managing the computer flexibly has produced great results. In virtualization, many devices can be controlled from a single central computer.
Success in a Short Time
Virtualization systems were first created to provide flexibility only on physical hardware. The server virtualization process in the VMware trial has been a tremendous success, and the definition of virtualization has expanded further over time. Today, it is possible to see the signature of virtualization in almost all areas of information technology.
Virtualization is most commonly used in operating systems. If any other operating system on any system goes through virtualization, the device in question is called a virtual PC. Essentially, virtualization is no different from any file in the computer. Just like other files, you can delete, rename, move. You can even copy your Virtual Machine file to a new computer.
In virtualization, which creates highly economical results, computers are completely independent of each other. They can run different programs on a single machine. This allows you to test any system easily and quickly. For example, you are using XP, but you want to switch to Linux for a long time. With small risks, you can do this type of test on a virtual PC in a lossless manner. Depending on your creativity, it is entirely up to you to use your virtual computers in many functional areas.
Types of Virtualization
There are four types of virtualization:
- Network Virtualization
- Server Virtualization
- Operating System Virtualization
- Storage Virtualization
Network Virtualization: It is possible to provide end-to-end service through the created network environment. Virtual networks are created through multiple service providers. Today, many organizations, small or large, are going to virtualize their networks.
Server Virtualization: The most common type of virtualization. Resources are pooled and distributed in a common pool. Significantly improves both efficiency and performance.
Operating System Virtualization: You can transfer applications to other virtual computers. Various updates, patches, etc. all servers at the same time. It also allows you to maintain your OS while your programs are running.
Storage Space Virtualization: Consolidates physical storage devices into a single space. Consolidates storage areas in separate networks into a single area.
What are the Benefits of Virtualization?
Contrary to its disadvantages, virtualization comes to the fore with its benefits. The diversity of its benefits is the most important reason for the widespread use of this technology today. Let's take a quick look at the benefits of virtualization:
Virtualization is not difficult to manage. A medium level of computer knowledge is enough to install and manage the system.
Virtualization eliminated the problem of compatibility in operating systems. In the past, mismatches could occur between the computer and some operating systems. Currently, it is possible to install multiple operating systems within a single computer.
The detection of errors is now much faster.
Security level increases with access control. The problem in one virtual device does not affect other devices. Other devices continue their journey smoothly.
It enables more efficient and efficient use of resources.
Prevents possible data loss.
Prepares the ground for tests without risk.
It prevents increasing costs such as cooling, electricity, and equipment.
You can flexibly separate the application or service of your choice. In this way, you do not waste resources.
Virtualization Programs
You can use a variety of software or programs to implement virtualization processes in a practical way. It is also possible to turn to some manual methods. VMware Workstation for Virtualization, Virtualbox and Parallels Desktop are among the most popular software. In order to virtualize CDs, Daemon Tools is very common.
Why Virtualization?
When the idea of virtualization was first introduced, the main motivation was the economy. Desired success was achieved on the way out with the goal of producing many things from a single center. With virtualization; one physical server provides productivity as if it had a large number of the hardware. This is indeed a small-scale revolution for computer technology. It has become possible with virtualization technology to easily make room for new servers on just one computer. In particular, the communication age has begun to highlight these requirements even more clearly. In this way, users' requirements for physical servers have been significantly reduced. This means getting rid of very serious costs.
After virtualization, a very significant reduction in CPU usage has occurred. In general, physical servers violated more than 10% of the CPU. Now after virtualization, this rate has dropped to around 5%. All these reasons and privileges must be sufficient reasons to meet virtualization technology. Virtualization would be a very smart way for you, especially if you run an organization that runs on a computer.
