Get to know Kernel Virtual Machine (KVM) VPS and its advantages and disadvantages

Speaking of operating systems or OSes, do you know about Kernel Virtual Machine or KVM? KVM is a core part of any operating system, such as Linux or Windows OS.

Before understanding more about Kernel Virtual Machine or KVM, let's get acquainted with Kernel. The Kernel in an operating system is like the heart in the human body. The Kernel is the core part that makes the operating system intact and works like an operating system or OS on a computer system.

Linux or Windows are widely used everywhere and would only be the operating system you know today if they had their heart, the Kernel. It's like Linux, just a program inside an operating system.

The operating system can fully control a system on a computer network, and so does the Kernel on the operating system. The ability of the Kernel to have complete control over the operating system also gives the Kernel control over the computer network system.

When you turn on the computer, and the computer system starts, the Kernel is the program that will be loaded in the second order after the bootloader. The Kernel has essential functions like task, memory, and disk management. In addition, the Kernel also functions as an interface provider between hardware users and hardware components in a system.

Let's take Linux OS as an example. Basically, Linux distribution or Linux Distro is different from the Linux kernel. The difference is that the Linux kernel cannot stand alone like Linux Distro. The Linux kernel requires specific programs to become a complete OS and be used by its users.

On the other hand, when using a Linux Distro, you automatically get the programs designed in a bundle. Although, you have to install these programs independently through the built-in CD/DVD.

After learning about the Kernel, what is a Kernel Virtual Machine or KVM? To get more information about Kernel Virtual Machine or KVM, Cloudmatika will specifically review KVM from an understanding of its advantages and the differences with OpenVZ. Read the article until the end to get the information.
 

KVM stands for Kernel Virtual Machine, which, as the name suggests, is definitely virtual. If you find the term virtualization on a hardware device, then the term virtualization shows you that the hardware is made virtually or digitally. The result of the virtualization process is called a Virtual Machine (VM).

KVM is a virtualization technology developed by Linux. KVM is a technology that works inside the Kernel of the Linux OS. Its development does not stop there; KVM also has products from its use, namely Virtual Private Server or VPS.

Linux-developed KVM is known to be superior when compared to other virtualization technologies you can find. Want to know what are the advantages? Here are the benefits of KVM that you need to know.
 

This KVM VPS can also be used for various operating systems. Some are Linux Distros such as CentOS, Debian, or Ubuntu. Linux Distro and KVM can also be enjoyed on other OS that suit your wants and needs. For example, UNIX or Windows.
 

The average KVM VPS is favored by technicians in the world of information engineering or network systems to web developers. KVM VPS performance is considered efficient because it comes from the Linux kernel that underlies this virtualization technology.
 

Dedicated resources are dedicated servers for users without having to share them with each other. Apart from dedicated resources, there is also something called shared resources. Shared resources are the opposite of dedicated resources.

VPS KVM itself uses dedicated resources. The existence of dedicated resources is what makes VPS KVM able to deal with high network traffic. Therefore, VPS KVM suits a company's network system with an increasingly large website.

Especially for those of you developing an online business, VPS KVM is perfect for your website because it will be able to help deal with the product checkout process, payment process, customer database storage, and product catalog.

VPS KVM is considered to have smooth performance because it has its own RAM and CPU. In addition to the advantages in RAM and CPU, this VPS KVM is accompanied by the benefits of Virtual Memory Management or VMM and memory manager, which can help KVM performance even faster.
 

KVM VPS is accompanied by a feature called live migration, whose primary function is to facilitate migrating or moving Virtual Machines (VMs), either moving the hardware alone or moving the hardware from one location to another. Thus, there will be no downtime and other disturbances that could hinder the migration process.
 

KVM uses a security system that combines Security-Enhanced Linux (SELinux) and Secure Virtualization (sVirt), which can guarantee the security of your data. In addition to data, the protection offered in KVM can also prevent errors in the KVM process.

The last advantage is that the VPS KVM data center is in Indonesia. VPS KVM can be an exciting option for those who want to use this virtualization technology because the close data center makes website access faster.

Virtualized technology products developed by Linux are not just KVM. You should know OpenVZ, which is also developed by Linux OS but is container-based. OpenVZ actually comes before KVM.

To choose between KVM and OpenVZ, you must know the differences between them. To understand some of these differences, you must know the differences between KVM and OpenVZ.
 

Although both are virtualization technologies, OpenVZ does not use this virtualization as a whole. KVM will use virtual servers as a whole. Meanwhile, OpenVZ will virtually divide the physical server for the OS level only in the container section.
 

The first difference is in the compatible OS. You already know that KVM is compatible with several OSes other than Linux. Whereas OpenVZ only works for Linux.
 

When looking at the resources owned by KVM and OpenVZ, KVM still occupies a position for faster and more stable performance. This is because the server is close to dedicated resources. Meanwhile, OpenVZ is still below KVM but above shared resources.
 

When compared, OpenVZ will be more affordable than KVM. This is because KVM uses comprehensive virtualization and requires various hardware with a more complicated system. OpenVZ also requires hardware and virtualization like KVM, but it is simpler than KVM.

Have you made your choice between KVM and OpenVZ? If you still need clarification, consult your company's needs with Cloudmatika. Cloudmatika offers Virtual Private Server services, both container-based and virtual machine-based, which you can choose. Contact us here for more information about the VPS package you want!
