VPS Hosting 2021 – What it is and how it works

VPS is the abbreviation of Virtual Private Server in English. It is a virtual server instead of a physical server. The latter can host multiple virtual servers. The main resources of a physical server can be shared between several virtual servers.

Compared to shared hosting without dedicated server space, it is a more secure and stable solution. However, it is smaller and cheaper than renting a full server. VPS hosting is generally chosen by webmasters who have mid-level traffic that exceeds the limits of shared hosting plans, but who do not yet need the resources of a dedicated server.

How does a VPS hosting work?

A server is a computer on which your web server stores files and databases required by the website. Whenever an online visitor wants to visit your website, their browser will send a request to your server and transfer the necessary files over the Internet. VPS hosting provides virtual servers that simulate physical servers, but in reality, computers are shared among multiple users.

With virtualization technology, your hosting service provider can install a virtualization layer on top of the server operating system. This layer divides the server into multiple partitions and allows each user to install their own operating system and software.

Therefore, a virtual private server is both virtual and private because you are in full control. At the operating system level, it is separate from other server users. In fact, when you want to run multiple operating systems (such as Windows and Linux) without rebooting, VPS technology is similar to partitioning your own computer.

Running a VPS allows you to build a website in a secure container that has guaranteed resources (memory, disk space, processor cores, etc.) that do not have to be shared with other users. With VPS hosting, you have the same root-level access rights as renting a dedicated server, but the cost is much lower.

VPS hosting versus other types of web hosting

Different types of web hosting allow you to do different levels of customization on the server. They differ in price, performance (eg page load time), and service availability (eg uptime). Below is information about VPS hosting compared to other hosting solutions.

Shared hosting

Shared hosting is a solution for website owners with low traffic. This is the starting point for most small businesses and bloggers. With shared hosting, you can share the same physical server with multiple other clients of the hosting company. You don’t have dedicated resources because your site runs on the same operating system as other sites.

Therefore, the memory and computing power available to your site will be affected by the needs of other users of the service. For example, if the number of visits to a website hosted on the same server suddenly increases, the page load time may increase. You also cannot choose the operating system and other server software, because all users use the same settings. Generally, your hosting provider handles all aspects of a shared hosting environment.

You can think of shared accommodation as renting to share the same apartment with multiple roommates. VPS hosting is still a form of location, but everyone has their own room and can customize the space based on their needs. For example, they choose paint, furniture, decoration, etc.

Cloud hosting

With the cloud hosting, you will no longer use a single server, but a cluster running in the cloud. Each server in the cluster stores the latest copy of its website. When one of the servers is too busy, the cluster will automatically redirect traffic to the other server. So there is no downtime for cloud hosting because the server cluster can still respond to requests from your website visitors.

Cloud hosting and VPS are not mutually exclusive. In contrast, many web servers provide VPS hosting on cloud infrastructure. This is also the solution we chose at Hostinger because we found that the combination of VPS and cloud technology can provide the highest performance and reliability in a virtual server environment.

WordPress Hosting

WordPress hosting is a service specially provided for website owners operating with this popular CMS. It comes with some WordPress related features, which can only be used if you have a WordPress website, such as one-click installation, pre-installed plugins, or the WP CLI. The server has been configured to meet the needs of WordPress. Therefore, hosting providers offer WordPress hosting as part of their shared hosting services.

Although it is also possible to set up a WordPress site on a dedicated virtual server, you cannot access a custom server that has been considered for WordPress setup. However, if you always choose a VPS for your WordPress site, you can configure the hosting environment to suit your business needs.

Dedicated hosting

With dedicated hosting, you can rent a complete physical server for your business. If your website is busy, dedicated hosting may be your best option because dedicated servers are fast, flexible, and fully customizable. However, the service also comes with a price tag, so not everyone can negotiate, especially if you have a small or medium-sized website.

VPS hosting lets you select and configure server operating systems and applications, while dedicated hosting goes one step further. It not only allows you to configure the software, but also the hardware, because the whole server is yours and nobody has said anything about the configuration. You can also run a dedicated server on a premises (for example, in an office), but in this case, you will lose the support of a professional hosting team.

Advantages and disadvantages of VPS hosting

If you really need VPS hosting, it may be the ideal solution for you. The following are the advantages and disadvantages of using virtual private servers.


  • It is faster and more reliable than shared hosting servers.
  • Since server resources (such as memory or processing power) are guaranteed, available resources fluctuate from zero to smallest.
  • User problems from other servers and increased traffic will not affect your site.
  • Gains superuser (root) access to the server.
  • Since your files and database are locked by other users on the server, you can get better privacy.
  • This is an easily adaptable service. As the website develops, you can easily update the server resources (RAM, CPU, disk space, bandwidth, etc.).


  • It is more expensive than shared hosting.
  • You need more technical knowledge to administer the server.
  • Misconfigured servers can create security holes.

When to use VPS hosting and when is the time to update it

Usually this is the next step after your website goes over the shared hosting limit. If a more advanced shared hosting plan is no longer enough to run your website smoothly, it is worth upgrading to a VPS plan. In this case, it can provide you with the best of the world’s dedicated and shared hosting.

However, in some other use cases, it may be a good idea to run the VPS plan from scratch. For example, an e-commerce website that needs to ensure secure payments in a fast and stable environment can greatly benefit from virtual private servers. In fact, if you store sensitive information or need to process payments online, VPS can help reduce the risk of security breaches and identity theft.

If you expect traffic to your site to increase at some point, such as event planning or ticketing sites, a VPS hosting plan can also be a good solution. Game servers and other resource-intensive sites may also perform better on virtual dedicated servers.

Are there other options? What is a managed VPS?

One of the biggest pitfalls of VPS hosting is that you manage the entire server environment yourself. If your virtual server is not properly configured and maintained, you can face serious security risks and performance losses. Managed VPS hosting services have appeared on the market as a viable method to solve this problem. It can be considered as an improved alternative to VPS hosting with full technical support.

Hosted VPS is still something new on the market, but more and more hosting service providers are providing this service to their customers. For example, at Hostinger, we aim to provide a fully managed hosting environment for all of our cloud hosting plans. We configure the server according to your needs, take care of server uptime and monitoring, support backup and caching, and provide 24/7 dedicated support for all of our clients.

To conclude, why choose a VPS hosting?

With VPS hosting, you can access guaranteed resources and full control without using your own server. For medium-sized, high-traffic, resource-rich ecommerce and ecommerce sites, this is a good solution. However, companies that are expected to grow rapidly can also benefit from the stability of the service. If you want a reliable and affordable hosting environment, VPS hosting for your website is definitely worth considering.
