Do you know what it is virtual private server? VPS is one type of hosting that is used to store data from a website or apps.
In the audit process, VPS is often used as an audit object, because its function is to store important data.
To better understand what it is virtual private server, please refer to the explanation in the following article.
What is Virtual Private Center?
A Virtual private server (VPS) is a hostingservice that provides a virtual server which functions like a dedicated server , as users can run the server in their own environment.
VPS offers a separate operating system, resources, and configuration for each of its users.
This allows users to run server with dedicated resources without being restricted or interfering with other users' systems.
In addition, you also have full rights to manage and control the operating system to be customized according to needs.
Therefore, even though each VPS resides on the same physical server , each user’s VPS environment is isolated. This not only allows the server to operate without affecting other operating systems but also mitigates the risk of malware since the VPS environments do not intermingle.
How a Virtual Private Center Works
Now that you’ve learned enough about what a virtual private server is, you need to understand how a VPS works.
Basically, understanding what it is virtual private server can be analogous to a unit in an apartment building that has its own resources, such as electricity, water, and facilities that are not shared with other residents.
So how does virtual hosting work? A VPS operates quite simply: it divides the main physical server into several virtual server that function independently.
Like an apartment building that consists of many units, each with its own utilities.
Virtual Server can be managed and configured flexibly and according to the user’s needs, just like a fully dedicated physical server , without any interference from other users’ VPS instances on the same server .
The allocation of resources, such as CPU, RAM, and storage, is managed using virtualization technology that creates a virtualization layer on top of the primary server operating system.
Thus, the virtualization layer allows users to install the OS, organize files, and run applications or website without affecting the configuration of other users.
Simply put, the way VPS works is done by creating an environment server different from the environment server the main physical, so that each user has control and flexibility over their respective VPS.
Functions of a Virtual Private Server
In addition to serving as website hosting, VPS has other functions that also require server infrastructure that can be widely customized and require large resources.
Among what are the functions virtual private server is as follows:
1. Website Hosting
VPS is suitable for-host website which requires better speed, stability, and security than shared hosting.
With a VPS, users will enjoy stable resources unaffected by other users, customizable security, and the ability to handle high traffic spikes.

Compared to free email server services, VPS provides many benefits, one of them in terms of its security that can be configured independently.
4. Data backup
VPS as data backup it doesn't just act as a storage area. Then what is virtual private server as backup data?
VPS offers greater capacity tailored to your needs, secure storage, and automatic backups without disrupting the main server .
5. Game servers
Game servers essentially require high performance, including a stable connection, substantial resources, and robust security measures to prevent attacks or cheating.
It is clear, then, that a VPS can meet all the needs of a game server and enable it to operate more efficiently and smoothly, without any interruptions.
Advantages and Disadvantages of a Virtual Private Server

a. OpenVZ
What are the advantages of an OpenVZ virtual private server? It is more cost-effective because, when resource are not fully utilised, they are shared with other VPS users—which is both an advantage and a disadvantage.
This technology will be quite efficient if your application or website does not require a lot of resources. Different if need be resource You big ones are going to end up grabbing each other resource.
b. KVM
What are the advantages of a KVM virtual private server? It provides fixed resource allocation that matches what the VPS user has ordered,
Therefore, even if only 2GB of the 4GB is used, the remaining storage will not be shared with other users. Put simply, KVM virtualisation technology provides you with 100% of the allocated storage without having to compete with other customers.
5. RAM and CPU
The next consideration is to choose a package service that suits your website or application resource needs.
In VPS, packages will generally be offered based on the amount of RAM and CPU, so the larger the number, the more optimal the performance will be, which of course will be the higher the price.
