KVM is one of the most efficient technologies used in VPS hosting today. A VPS Server that uses KVM is built within a Linux Kernel, making it function like a Hypervisor and is known to be highly reliable and yield the best system performance. The Hypervisor is the core program that helps isolate the machines into individual systems from the host machine. These smaller systems are also called guest machines. Thus, with the kernel running on the root node, you can create and operate multiple virtual machines on the same server.
Now that you are aware of what KVM is and how it functions, here are a few more important elements that can help you understand the functioning of a VPS server better.
Things you should know about KVM VPS Hosting.
KVM offers better security against DDoS attacks.
DDoS or Distributed Denial of Service attacks are rampant across websites and can cause long-term harm to your website and all its assets. Since they are embedded within daily site functions, they do not seem prominent and hence, need to be tackled at the deeper level of data. With KVM, you can avail of the added layer of security to your server system and keep it protected from future attacks.
KVM has better advantages than OpenVZ.
KVM and its performance are often compared with OpenVZ. OpenVZ relies on the host node’s kernel and is based on the server’s containers. KVM, on the other hand, relies completely on virtualization and runs on the root node, thus being completely independent of the rest of the system. This allows you more opportunities for customization and control over your VPS server.
KVM is easy to operate.
With KVM, you can easily run a 32-bit operating system on one of the guest machines over a 64-bit OS on the host system. This works in benefit of those who are still using an older server system as a virtual machine. Thus, when you use KVM, you can save on the cost and other resources of having to change your entire operating system.
KVM offers better isolation of server.
Isolation of servers is perhaps the best feature of VPS hosting, making it work as a dedicated server but without the steep costs of dedicated hosting. With KVM virtualization, it works as the second level hypervisor that separates the guest machines from the host system. Thus, in the case of any mishap on one of the other smaller servers, your account remains unaffected and continues to function normally.
KVM allows you to run across a wide range of the system.
KVM can run on almost all currently used operating systems like CentOS 6 / CentOS 7 / Ubuntu 16.04 / Fedora 23 / Debian 8, Plesk Onyx, etc. Additionally, you can benefit from virtualization of hardware, CPU, storage, network, and bandwidth, on each of these systems.
Summing Up…
KVM is one of the most reliable, secure, and flexible technologies, that gives VPS hosting its advantages. To reap its benefits, you should always ask your hosting provider about their VPS system and what they offer. Always research well and assess your requirements, so you can opt for the best hosting solution for your website.
