With a growing demand for customized site experiences, Linux VPS has become a desired hosting type for many site owners. It offers the features of a dedicated server while the costs are marginally higher than a shared hosting plan. If you are currently using a shared hosting plan and want to upgrade but a dedicated server is exceeding your budget, then a Linux VPS Hosting plan is just what the doctor ordered. However, before you opt for VPS Hosting, it is essential to understand virtualization, which is the fundamental concept of a VPS server. Today, we will talk about how a KVM Hypervisor functions and why you need to look for it in your VPS Hosting plan.

What is Virtualization?

In simple terms, virtualization is a way to you create a virtual version of a software or hardware of a computing environment. It enables you to launch multiple applications or even operating systems on the same physical hardware.

When it comes to VPS hosting, a server virtualization software is used to create a virtual server where your website resides. This is known as the hypervisor. It separates the hardware resources on the physical server and generates several small virtual servers work in isolation from each other and have dedicated resources.

With a basic understanding of virtualization and hypervisor, let’s look at the KVM Hypervisor:

KVM Hypervisor

KVM or Kernel-based Virtual Machine runs on a Linux VPS server. This technology converts the kernel into a hypervisor to create several virtual servers. KVM isolates servers on the host machine. Once virtualization is added to the standard Linux Kernel, the resulting server environment benefits from the work on the kernel itself. In simpler terms, in a standard server environment, the CPUs are controlled by software, and the absence of direct access to hardware usually resulted in lower performance. However, with KVM, this problem is overcome since the CPU now connects directly with the hardware.

The KVM Hypervisor makes the management of the system performance easy. It allows the server administrator to manage the physical hardware for all virtual servers. It drives virtualization and allows for the optimum utilization of physical resources through virtual machines. KVM enhances the scalability and speed of the hosting environment. It also offers a high level of security via Mandatory Access Control (MAC) which restricts resource owners to deny or grant permission to access objects. The system admin defines the MAC criteria which are enforced by the security kernel. This makes it impossible for end-users to modify them.

Summing Up

Therefore, for highly secure, lightning-fast, and scalable VPS Hosting service, you need to look for one with KVM Hypervisor. It is one of the most flexible technologies which adds an extra edge to a VPS server. We hope that this article helped you understand a KVM Hypervisor and its functions.
