What is Server Virtualization

Server virtualization is emulating a physical server into multiple virtual servers. It’s a popular technique for maximizing server resources and reducing costs. In this article, we’ll explain server virtualization and how it works.

What is Server Virtualization?

Server virtualization is creating various virtual servers from a physical one. Each virtual server can manage its operating system and applications and function independently from the others. 

Virtualization allows for greater server utilization, flexibility, and easier management and maintenance.

The main reason for developing server virtualization was the necessity to facilitate the utilization of resources and the ability to support the separation between the clients’ operating systems for safety purposes.

How Does it Work?

The server virtualization technique allows businesses to run various applications and operating systems on the same physical server, leading to significant cost savings.

So how does it work? Server virtualization software creates a virtual layer between the physical server hardware and the operating system. 

The first step is creating the hypervisor, which is the virtualization software. It allocates resources to each virtual server to function like a physical server. In other words, a hypervisor creates the layer that separates the physical resources such as CPU, RAM, or others from the virtual servers.

After installing the hypervisor on your hosting device, you can use that virtualization software to create a new virtual server by emulating the physical resources.

Furthermore, you should be aware of different types of server virtualization. The main distinction stands on their isolation level, which is also related to how many hardware resources they emulate.

There are many benefits to server virtualization, but one of the most appealing is the ability to consolidate multiple servers into a single one. 

This can significantly reduce data center costs since you need fewer servers, less power, and less cooling.

Standard Models of Server Virtualization

• Full virtualization is when a software program simulates all the hardware required for a second operating system to run. 
• Para-virtualization is when a software program provides a modified operating system to run more efficiently on virtual hardware. 
• OS-level virtualization is when a single physical server is divided into multiple isolated environments. 

Conclusion

Server virtualization stands for dividing a physical server into multiple virtual servers. Every virtual server can run its operating system and applications independently of the others. 

Virtualization can be a great way to provide your business with the IT services it needs. The benefits include increased server ability, cheaper operating costs, and an easy deployment process for new workloads or updates! 
If you’re considering implementing server virtualization in your business, be sure to consult with an IT professional to ensure it’s the right solution for you.
