Virtual Private Server (VPS) Hosting ensures superior control and isolation for websites through server virtualization and hypervisor use.
By utilizing these technologies, VPS Hosting enables the creation of multiple virtual servers on a single physical server, each operating independently with dedicated resources.
This setup guarantees privacy, isolation, and control for each virtual server, providing complete root access, account isolation, and separate IP addresses for enhanced separation and security.

What is VPS Hosting?
VPS hosting is a type of web hosting that uses virtualization technology to give users more control and flexibility than shared hosting while maintaining affordability.
A VPS is created by partitioning a physical server into multiple virtual servers, each acting as an independent server. This allows VPS users to have their own operating system, applications, and data.
VPS hosting provides control, privacy, and dedicated resources. It’s ideal for those needing autonomy and security without sharing a server.
Each website operates independently with allocated resources, ensuring performance and isolation.
How Does VPS Hosting Offer Control and Isolation?
VPS hosting gives you total control and keeps your website separate from others.
You can customize your virtual server settings specifically for your website. Plus, it protects your site from issues on other websites sharing the server.
Server virtualization allows multiple virtual servers to be set up on a single physical server. A hypervisor then ensures privacy, isolation, and control for each virtual server.
VPS Hosting relies on two main things: server virtualization and hypervisor. Server virtualization lets one physical server host multiple virtual servers.
A hypervisor, software, or hardware is installed on the physical server to ensure each virtual server has its own privacy, isolation, and control.
The hypervisor creates Virtual Machines (VMs), which act as separate machines.
These VMs use resources from the main server. Each VM gets its own set of resources, making it operate like an independent server. Many VMs can run on one server, each isolated from the others.
Isolation Using IP Addresses
As every virtual server has dedicated resources, complete root access, and account isolation, the web hosts assign separate IP addresses to each VPS.
It creates more separation by removing the connection through the IP address. In shared servers, user accounts aren’t separated.
If one user sends spam emails, the shared IP address could get blocked, affecting everyone else on the server.
Hence, due to one user’s fault, the rest of the users on the server will also be unable to send important emails. In VPS Hosting, each VPS has a separate IP address which helps to isolate users from each other.
There are many ways to offer control and isolation to a VPS, but one of the most effective ways is using IP addresses. An IP address is a unique identifier for a device on a network. Therefore, by assigning each server its IP address, you can ensure that they are isolated from each other and can only communicate with authorized devices.
Another advantage of VPS Hosting is the control it provides through full root access. Let’s explore this further.
Full Root Access in VPS Hosting
One of the most significant advantages of VPS Hosting is root access.
The word root refers to a username used across all Linux operating systems. The root user is presumed to be the system admin, has access to all files, and can do anything; if you have the ‘root’ username credentials, you will have root access to a server.
Shared Hosting plans aren’t offered with root access because there’s no isolation of websites, which means everyone has access to the same field. So, unilateral changes that one website owner makes can harm other websites.
VPS Hosting provides full root access to users, giving them complete control over their virtual private server.
Full root access allows users to install any software they need without restrictions and to change their server’s configuration.
However, VPS Hosting offers complete, comprehensive isolation. Thus, any changes you make to the server will affect only your virtual machine (VM). All other VMs, and therefore all other websites, remain entirely unaffected.
With this being the case, web hosting companies offer root access with their VPS Hosting plans.
Why Is Root Access Essential?
As your website grows, you’ll need more control over its operation. For example, you might want to install security software that your web hosting company doesn’t natively support.
You may also want to change the server configurations or optimize your server for better performance.
To achieve these tasks, you will need complete control over your server; root access can only provide that function. Thus, root access allows you to set up your website and server exactly how you want them.
Root access is essential for many tasks, such as installing software and managing system files. In addition, you would be unable to perform server administration tasks without full root access.
Root access is a key feature in VPS and Dedicated Hosting. It is affordable in VPS but expensive in Dedicated Hosting.
Therefore, it’s usually only used by websites with high traffic and opted for by people who can afford Dedicated Hosting.
How Does the VPS Hosting Control Assist Website Owners?
By Improving Website Security
When you have root access, you don’t need the permission of your web hosting company to install third-party applications or software of your choice. You can also close all unused ports to prevent hackers from exploiting those ports to attack your website.
Additionally, you can restrain access to the internet since it is not necessary for all applications on your server to be connected to your website every second.
However, each online application is likely to pose a risk. Still, with root access, you can disconnect the applications from access to the Internet.
These are some of the essential security optimizations you can make to your website with VPS hosting.
By Improving Website Performance
Root access helps you enhance the speed of your website in different ways; two of the most important are:
- Optimizing JavaScript delivery
- Allowing to disable hotlinking
Optimizing JavaScript Delivery
When a browser accesses your website, the server sends information to it through images, videos, files, text, etc. One of the files that your server sends is called the Javascript file, and browsers will not open a website until the Javascript file is read. Thus, it takes time, and as a result, it will reduce the site speed.
With root access, you can modify the settings so that the browser loads the website first and then reads the JavaScript file in the background, increasing the website’s speed.
Allowing To Disable Hotlinking
Hotlinking is like stealing bandwidth. and if it happens for an extended period, it can impact your server performance significantly. However, with root access, you can disable hotlinking altogether.
Conclusion
Account isolation of the VPS server functions as a Dedicated Server. Hence, if you are looking for Dedicated Server-like hosting solutions at a lower cost, VPS Hosting is your optimal option.
Furthermore, account isolation ensures better security for your account than most traditional hosting services.
The primary benefits of VPS Hosting include control and isolation, along with the dedicated allocation of resources, which are guaranteed through its unique architecture powered by server virtualization and hypervisor.
