What is a Hypervisor? What are the Advantages of Using Hypervisor?
Virtual Private Server Hosting environment, or simply VPS runs on the process of virtualization. And at the foundation of such a process is a technology called Hypervisor. Before we dive deeper into what Hypervisor is and what it can do, it is important to understand the landscape of virtualization.
As the name suggests, Virtualization is the process or the system of creating a ‘virtual’ version of a resource. It could be the server, the desktop, operating system, storage, data, or even the network. Surprisingly, Virtualization has been in existence for decades, but are only enhanced and modified to serve modern hosting and computing needs. Virtualization can be of three types – operating system virtualization, hardware virtualization, and server virtualization.
The process of virtualization transforms the entire process of a traditional hosting system by consolidating workloads and building an entire network of multiple servers on a single physical system. The underlying main hardware system is partitioned, with each partition running as an independent, isolated Virtual Machine. Each such machine has its own operating system and other resources required to function. This is where the role of Hypervisor comes in.
What is hypervisor
A hypervisor is a layer of a program which enables the individual server on a VPS environment to host and run multiple virtual machines. It helps partition the physical hardware, thus abstracting and isolating the different operating systems and their respective applications from the main physical system. So, in a way, virtualization is actually enabled by the hypervisor. This means that the host machine can independently run and operate multiple virtual machines (also called guest machines). With the help of Hypervisor, it becomes easier and more efficient to manage the individual machines by distributing resources like memory and storage allotment, CPU usage, network bandwidth, and data files. The Hypervisor is capable of managing the communication between the virtual machines, thus keeping them connected, but virtually so. It also controls the starting and stopping of the virtual machine as and when requested by the server admin.
Advantages of Hypervisor
It protects your server.
One of the biggest benefits that one can derive from the process of virtualization, is that the virtual servers remain exclusive of each other. This protects one machine from another. Unlike generally seen in a common hosting environment, where an external threat to the main server can cause the user accounts to get affected. In virtualization, the Hypervisor keeps the machines and their respective resources isolated, and thus safe. Even if one of the virtual machines get affected by an attack, the other machines continue to function normally.
It helps optimize the server resources
Deploying separate physical servers for different applications is not only cost and time-consuming but also burns tech resources, space, personnel, etc. With Hypervisors, site owners can make the most of server hardware and reduce wastage of space, time, and energy.
It gives you more control
Admins have more control over the server and can manually set the configuration, thus customizing the server and its resources according to the site needs and the ultimate business objectives.
You can make the most of any technology when you have the right kind of resource. And the right resource only comes from the right provider. If you are considering opting for VPS hosting India service, then it is important to find the right hosting provider and a right hosting plan.
