What’s VPS – Virtual Private Server

VPS hosting is usually chosen by website owners who have medium-level traffic that exceeds the limits of shared hosting plans but still don’t need the resources of a dedicated server.

What’s VPS?

VPS stands for Virtual Private Server. VPS hosting is one of the most popular hosting services you can choose for your website. It uses virtualization technology to provide you with dedicated (private) resources on a server with multiple users.

VPS hosting allows you to store your web assets on space that has been configured to look and feel like a standalone dedicated server.

A VPS is a siloed space on a server that has the characteristics of an entire server itself. A virtual server hosting has its own Operating System (OS), applications, resources, and configurations. All of this is contained within a single powerful server. Each server can have multiple VPS accounts on it.

How Does VPS Work?

As the name implies, the entire premise of VPS hosting revolves around virtualization. With this technology, entire servers can be ‘split up’ and allocated to different people.

Virtual servers share a single physical server, but each gain the benefits of being able to set up and configure their space as if it were wholly belonging to them. This gives them a high degree of flexibility along with an added element of privacy – for a fraction of the cost of a dedicated server.

Virtualization technology assesses the server as a whole and then divides resources up among different accounts based on what those account holders paid for. For example, if the server has 128GB of RAM, it may split that up in 2 or more parts.

Each account holder will then be assigned the amount of RAM as specified in their hosting contract. The resources allocated to each account are only for that account and will not be tapped into even if other accounts need or use more.

Virtual Private Server Pros

  • Price. Virtual Private Servers (VPS) are relatively cheap. Compared with dedicated servers of the same class, they offer much more raw server power, despite being virtual. And they are only slightly more expensive as compared to regular web hosting plans, while offering much, much more options.
  • Setup. A VPS server can be created much faster than a dedicated server, which has to be assembled and then installed. This means, that your virtual dedicated server can be ready in a matter of hours, with all the needed software installed there.
  • Flexibility. There are more VPS servers on offer than Dedicated Servers. This is due to the fact that they resemble the regular cloud web hosting plans a bit. This means that you can always find a right solution for you in terms of price and features.
  • Root access. Just like with a Dedicated Server, you will get a complete root access. This way you can perform operations typical of the stand-alone dedicated server environment – install additional modules and software, work directly with the server’s Operating System, etc.
  • Powerful. The Virtual Private Servers are always placed on very powerful machines, which can work with several VPS servers. This means that the physical servers are made of top-of-the-line hardware components. This allows for a VPS to sport tons of extra features, which will be missing from a dedicated server offer in the same price range.
  • Security. With a VPS server, the main server will be secured against most known DDoS attacks or security exploits, so you can sleep a bit easier when it comes to server security.
  • Easily upgradable. Since you are using just a part of the main server’s resources, you can always upgrade to use more almost instantly. With a Dedicated Server, you will have to wait for the hardware component to be installed on the server first before taking advantage of it.

Virtual Private Server Cons

  • Less powerful than dedicated servers. The VPS server may be perfect for a personal website or resource heavy applications, but if you plan to run a huge business portal with a huge forum section, which will be sending tons of emails per day and which will be running resource-hungry applications all at the same time, you will need a dedicated machine.
  • Limitations. Just like with the cloud hosting account, on the physical server there can be several VPS servers at a time. If one of these servers is consuming way too much CPU or RAM power, this can slow down the entire server, which can affect your VPS container, even if you are not connected in any way with the other server in question. There are several software limitations, which prevent this from happening, but experience teaches us that almost anything is possible.
  • Require more technical knowledge. Unlike the cloud web hosting account, the VPS server will require you to posses more technical knowledge to manage and maintain it.
  • Support will be slower. From the backend point of view, a support technician can solve a problem with a cloud hosting account much faster than a problem with a VPS server.

Now I think we have a basic ideas about VPS, next posts we will check what’s different between VPS & Shared hosting & Dedicated server and which is the best choice for your project.
