What is a VPS or Virtual Private Server? It is a method of partitioning or creating virtual environments from a physical server into different servers, so that all of them operate as a single machine/server. However, do you know how it works? Each VPS has its own software: operationally, it is like a dedicated server, the difference is that the hardware is shared. Each VPS is segmented to ensure allocation via virtualization. If you want to learn more about how this technology works, keep reading.
What technology does a VPS hosting use?
VPS servers operate through a VPS technology called Virtuozzo by Parallels. This technology’s main function is to generate a specific number of autonomous partitions within a single physical server. These partitions are fully independent from one another, so each has its own file system, as well as its own software and resources.
In this way, all resources from the physical server are evenly distributed among the different partitions or VPS servers. From an operational standpoint, they are dedicated servers. However, each client does not have a physical server exclusively for themselves, but rather a reserved hosting space within this unit.
Thus, the VPS server sits halfway between shared hosting and dedicated servers. There are many situations in which a user or company should opt for this type of server. On one hand, when shared hosting becomes insufficient and can no longer handle the needs or traffic of a website. On the other hand, somewhat related to the previous point, when the site requires more speed and isolation.
One feature that defines a VPS server is that each client can choose the operating system that best suits their needs. For example, we may have Windows VPS, VPS Linux Hosting, and VPS Ubuntu, among others. Which option is the best depends largely on what the server will be used for. If Microsoft applications are required, Windows is the best option; if open-source technologies are preferred, then Linux is the best available option.
What is the purpose of VPS hosting?
Conventional hosting stores your website or blog in a shared environment. In this case, multiple websites from various users and businesses share the same server.
On the other end are dedicated servers, which are synonymous with exclusivity. We’re talking about a computer with excellent processing power dedicated only to your site, which represents a truly premium service.
From these definitions, we can draw some conclusions:
- Conventional hosting is cheaper but offers lower performance;
- A dedicated server is more expensive but provides excellent performance.
- So, wouldn’t it be ideal to have a service that combines quality with an affordable price? Such a service exists, and it is known as VPS. It is something like a dedicated server but virtualized within a physical machine.
By opting for VPS, your site is hosted on a computer alongside other websites, but not as many as in traditional hosting. This means that the machine’s hardware resources are shared with fewer sites, which makes VPS an excellent option offering better performance at a more affordable price than a dedicated server.
How does VPS hosting work?
A server is a computer where your web hosting provider stores the files and databases necessary for your website. Every time an online visitor wants to access your website, their browser sends a request to your server and transfers the necessary files over the internet. VPS hosting provides you with a cloud-based server that simulates a physical server, though, in reality, the machine is shared between several users.
By using virtualization technology, your hosting provider installs a virtual layer on top of the server’s operating system. This layer divides the server into partitions, allowing each user to install their own operating system and software.
Therefore, a Virtual Private Server (VPS) is both virtual and private because you have full control. It is isolated from other users of the server at the operating system level. In fact, the VPS technology is similar to creating partitions on your computer when you want to run more than one operating system (such as Windows and Linux) without having to reboot.
A VPS allows you to set up your website within a secure container with guaranteed resources (memory, disk space, CPU cores, etc.) that you do not need to share with other users. With VPS hosting, you get root access just like you would with a dedicated server, but at a much lower cost.
When is it recommended to switch to a VPS?
If you have a large number of shared hosting accounts, we recommend moving to a virtual server service. This way, you can manage your hosting independently, just as in shared hosting, with the advantages of having exclusive resources assigned to your server. You'll also be able to create custom hosting plans for each account and adjust PHP parameters such as memory_limit or add additional PHP libraries for your server.
Virtual Private Servers occupy an intermediate space between shared hosting and a dedicated server. They are a good choice if your project exceeds the limits of a shared hosting plan.
Some of its advantages:
- It is faster and more reliable than shared hosting.
- Since server resources like memory or processing power are guaranteed, there is zero to minimal fluctuation in available resources.
- Problems and traffic spikes from other users on the server do not affect your site.
- You get superuser (root) access to your server.
- You get greater privacy since your files and databases are locked away from other users on the server.
- It is an easily scalable service. As your website grows, you can easily upgrade the resources of your server (RAM, CPU, disk space, bandwidth, etc.).
In conclusion, VPS hosting offers several advantages over traditional hosting. With it, you have more freedom, for example, to install applications and improve your hardware.
The price is also more economical than dedicated servers, and the fact that resources like RAM and CPU are not shared with other virtual servers ensures superior performance compared to traditional hosting.
