When you first dive into the world of virtualization
You will definitely come across the terms KVM, XEN and OpenVZ. All three terms are virtualization platforms commonly used in VPS. So, it’s no wonder that VPS can have good and outstanding performance.
Before we start discussing the types of VPS mentioned above, you should first know what a VPS is.
What is VPS?
VPS is a virtual machine that allows one physical server to be divided into several servers that run virtually.
As you know, one of the popular uses of VPS is to provide wider access for server managers.
Generally, the use of VPS is not too much because it requires higher operational costs.
However, thanks to the sharing of resources, VPS prices can be much cheaper than
with the same facilities.
So, when you want to use a VPS, there is no need to buy a physical server anymore.
However, this sharing process definitely requires a type of VPS, such as KVM, XEN and OpenVZ which will be discussed below.
3 Types of VPS You Should Know
If you want to use a VPS, make sure you know the information about KVM, XEN and Open VZ which will be explained below.
1. What is KVM?
KVM (Kernel-Based Virtual Machine) is a virtualization technology that you can develop and run using Linux as the operating system.
KVM is suitable for X86 CPU types (64 bit). In addition, KVM has hypervisor components because you can run this type of VPS directly on top of a physical server.
Therefore, KVM can be a stable host because it does not run on top of another OS.
There are several advantages that KVM has, namely:
When using KVM, you don’t have to worry about the activities of one virtual server affecting another, even though they are both on the same physical server resources.
This makes it more efficient as each VPS can use its own resources, without the need to intersect.
- Supports own RAM and CPU for All VPS
Each VPS in one system using KVM will have its own RAM and CPU.
Not only that, KVM has greater memory management and supports VMM (Virtual Memory Management) than other VPS virtualization platforms. So, server performance will be much faster than before.
The next advantage of KVM is that it can be used on any operating system. As a result, you are free to use it on any operating system you want.
There are several operating systems that support the use of VPM, namely Ubuntu, Debian, CentOS, Fedora, Suse to Windows operations.
- Migration Without Downtime
You can migrate between physicals from a running VPM. So, you can still run live without any constraints from the server service.
Of course, this migration will help those of you who want to switch hardware or share the load between hosts.
- High Level Security
KVM has a security standard that is a combination of SELinux (Security-enhanced Linux) and Secure Virtualization (sVirt). Thus, it will be difficult for intruders to access resources or control your VM.
2. What is XEN?
XEN was developed by Cambridge University and first released in 2009.
This virtual machine manager is open-source. From the beginning, Cambridge developed XEN so that the platform could operate hundreds of operating systems, even with just one computer.
For the way it works, XEN will allocate the elements contained in the physical server to each VM contained in the server.
- Save Time
This type of VPS only takes about 10 minutes to run a VM. So, you only need to create a dedicated storage network and install the software, then run it quickly.
You don’t need to perform complex configurations on your IT infrastructure. The reason is, XEN already has a variety of features that make its performance faster.
- Robust Server Management
XEN features the XENCenter Management Console that can optimize and integrate visual infrastructure with a more structured management process.
In addition, XEN is also equipped with VM Protection and Recovery so that it can perform protection, backup and recovery if something happens to the VM.
- Can Use Windows
Of course, you can run VPS virtualization with XEN on Windows OS as well as Linux operating systems.
3. What is OpenVZ?
OpenVZ is part of the types of VPS that have a Container base using the Linux operating system. The way it works is to allow the server computer to run multiple virtual machines with these containers.
OpenVZ is more economical than KVM and XEN because you can develop and deploy it open-source.
. So, you don’t need to buy a license first and can use it for free.
- Easy to Use
OpenVZ has a simple and fast way of using, starting from checking memory usage, number of processes, CPU usage, as well as disk usage capacity and others you can do easily.
- More Effective Resource Management
With this feature, you can easily divide resources such as CPU, RAM, dic and more.
The structure of OpenVZ is very simple, so it has stable performance. Not only that, OpenVZ can easily manage multiple containers at once.
OpenVZ has an independent container system. Each container can run independently on the kernel virtualization layer in the host OS. In addition, container systems are not tied to a single CPU, but can use any available CPU.
That’s the information about the types of VPS that you can know. If you want a VPS service that is efficient, has high security standards, and can be used on various operating systems, then KVM can be an option. However, other types such as OpenVZ and XEN can still be your choice.
