What is Server Virtualization? Benefits and advantages discussed

Server virtualization, Have you ever heard of it? You would be surprised at its importance and use all over the world. Now, since not many people know about server virtualization, we aim to explain all the important things.

What is server virtualization in cloud computing?

Understanding server virtualization is very important to many people, so we decided to explain what it is.

1]What is virtualization?

Virtualization is the creation of a virtual variant of anything. There will be no physical hardware, although it shares the underlying physical hardware with an operating system that acts as a host with virtual devices.

2]What is server virtualization then?

It is the process of creating virtual servers that act like real servers. To allow something like this to happen, virtualization is installed on a host computer that has been designed to provide the necessary computing power and hardware.

The problem with traditional server configuration is that they are usually designed to support single applications, which forces servers to run a single workload. This can actually waste resources, and nobody wants that.

Virtual servers are better because they allow businesses to reduce the cost of deploying multiple physical servers which will take up more space and use more electricity.

3]The hypervisor

Virtual servers can reach new heights using a layer of software known as a hypervisor. What is that? Well, it’s about abstracting the underlying hardware from all the software running on top of it.

Simply put, a hypervisor is similar to an emulator, virtualization software, if you will. It is designed to run multiple virtual machines on a single computer hardware and it is responsible for allocating resources on physical servers on the main hardware to different instances of virtual machines.

4]What are the two types of hypervisors?

There are two types of hypervisors that can be used without problems in a virtual server. The names are Type 1 and Type 2, and we are going to explain some things about them.

  • Type 1: In terms of type 1 hypervisor, also known as Bare Metal, it is more optimized because it is already installed on the hardware. Both the application and the guest operating system run on this hypervisor and allow the guest operating system to access the hardware. Not only that, but it works better due to the lack of a middle layer. From what we understand, a type 1 hypervisor is best when it comes to cloud computing and enterprise applications.
  • Type 2: When it comes to Type 2, also known as hosted hypervisor, it is capable of running on conventional operating systems like Windows, Linux, and Mac. This type of hypervisor will run applications on the host operating system, not to mention that it is easier to set up and run because it already comes with a host operating system. Compared to the Type 1 hypervisor, this version will suffer from reduced performance and increased latency.

5]Benefits of Server Virtualization: Benefits

Cost: A virtual server is cheaper because the user will not have to worry about hardware maintenance. This is a huge boon for businesses because their IT department won’t have to invest in on-premises resources or separate space to house massive physical servers.

  • Availablity: When you have a working virtual server, you won’t have to worry about availability in most cases. Most companies that offer server virtualization services have reported their products to have 99% uptime.
  • Efficiency: Another thing we like about virtual servers is their ability to improve efficiency. For example, automatic updating is a huge advantage and virtualization reduces the load on the resources at hand.
  • Energy savings: Since virtualization is neither hardware nor software, you can bet your bottom dollar that individuals and businesses will save a lot of money on their electricity bills. And if you’re the kind of person who cares a lot about the environment, then you’ll fall in love with server virtualization.

6]Advantages of server virtualization: disadvantages

  • Limitations: Because some applications are not virtualization-aware, some of your most needed tools may not work as they should, if at all.
  • Security: Because your virtual server is managed by a third party, it will be difficult to ensure that your files are safe from prying eyes. In the end, users should take their time to choose the best solution in this regard.

What is the difference between server virtualization and network virtualization?

Server virtualization is the separation of the physical server from the guest operating system, which provides additional benefits and functionality.

As for network virtualization, this is where network applications are moved to a network device, which also provides more features and benefits.

What is a server?

A server is a group of physical computers that run services designed to meet the needs of other computers on a network.
