What is KVM Server Technology in VPS Hosting?
Like every other traditional technology, the web hosting environment is also experiencing a rise of alternative systems like VPS Hosting. While the initial processes of setting up and running a VPS hosting platform might look complicated, it proves to be more efficient and sustainable in the long run. VPS runs on virtual servers, hosted on a single physical system. Each such VPS server has its own resources and can function as a private server, quite like in a dedicated hosting environment, only more cost-efficient.
The system of virtualization is driven by the program called Hypervisor, which helps isolate the virtual servers and enables them to run as a holistic unit on the physical machine. There are different kinds of virtualization technologies offered by VPS hosting providers. KVM or Kernel-based Virtual Machine is one of them.
What is a KVM Server?
KVM server is built into a standard Linux Kernel, making it function like a hypervisor. It allows you to run the kernel on the root node and thus, helps you to run multiple operating systems on the same server. KVM makes the hardware run on its own virtualization extensions. The hypervisor used by KVM is installed on the host machine, enabling it to manage the individual virtual machines, also called guest machines. The kernel of KVM acts as the second level hypervisor.
KVM server allows you complete control over your server resources, thus enabling you to configure the values on the machine as per your requirements. KVM can run a 32-bit guest operating system on a 64-bit host. So, if your admin/developer is using an older server system as a virtual machine, this makes the job easier. KVM can provide virtualization of existing hardware resources and help allocate the disk space, CPU capacity and time, network IO, etc.
Benefits of KVM server
While standard VPS hosting has its own benefits, KVM VPS particularly brings more benefits to the site owner. With a KVM VPS plan from competitive hosting providers, you can avail of a dedicated IP, SSD storage, DDoS protection, rDNS support, network with Tier-1 ISPs, WHMCS, reliable data centers, and run operating systems like CentOS 6 / CentOS 7 / Ubuntu 16.04 / Fedora 23 / Debian 8, Plesk Onyx, etc.
Needless to say, there are a host of web hosting providers available in the market today. Finding the right hosting plan and partner can go a long way is bringing out the best output from your site. So, before you make a decision of deploying one, you must cross check all necessary criteria and see if you get the right operational resources within a budget, and get round-the-clock tech support. Your hosting provider should be capable of driving the best performance of your site.
