What is a VPS (Virtual Private Server) and what is it for in a hosting

What is a VPS server

Many of you will wonder what is a VPS server, what is it for Y how is it different from a dedicated server. We will try to explain it in a very simple way to understand. A VPS server is a virtual server, located on a physical server (really any server is located on a physical server, including the popular “Cloud”), but unlike a Cloud server in a hostingthese types of servers are worse than Cloud servers for the following reasons.

Although a VPS and Cloud server may seem the same because they are both virtualized on a real physical server, in reality they are very different. VPS servers were born around the year 2001 when some hosting providers began to offer virtual machines using the technology of FreeBSD, LinuxVserver and OpenVZ. Basically what they offer is that in a very powerful physical server, they put several virtual machines with less powerful configurations, that is, as a result of a single server, they offer servers with less capacity using a single physical computer. When the client hires it, he obtains the access data to one of those virtual servers.

The client himself must configure his own server from scratch, including the operating system he wishes, although VPS providers greatly facilitate this task since we can choose which operating system to install from the administration console. However, we must have some knowledge of system administration to configure everything correctly.

The VPS solution is an intermediate step between the typical shared hosting where you do not get dedicated server space, and a dedicated server where we will have the entire server for ourselves and our project. A VPS is what is usually chosen for websites with medium level traffic, but that exceeds shared hosting plans.

Differences between a VPS and a Cloud in a hosting

  • A VPS server is not fault tolerant since it is located on a single physical server, on the other hand, a Cloud is fault tolerant, since it is on different physical servers.
  • A VPS server cannot guarantee the use of specific resources because of the technology it uses. On the other hand, a Cloud server may have guaranteed what the client who has hired it is using.
  • The latter leads us to a Cloud server you pay for what you are really consumingand on the other hand a VPS server does not.
  • On a VPS server when you run out of resources, the server could even crash, although the most normal thing is that it slows down, both for you and for the rest of the clients that are on the same physical server. If it is properly configured and sized this should not happen.
  • The Cloud servers are more expensive than VPS: VPS hosting servers charge you a fixed price each month, but Cloud servers bill you according to the resource consumption you make.
  • The Cloud server you can modify all the server resources from a console, that is, hard drives, CPU cores, amount of RAM memory, etc., on the other hand, you cannot modify anything with a VPS server, if you need to modify any aspect you will have to wait a while for them to “change” the supplied hardware.

Finally, VPS and the Cloud are not mutually exclusive, that is, hosting companies can decide to “set up” VPS on a Cloud infrastructure, and not just on a single physical server. With this we achieve that we do not notice at all if there is a hardware problem in a certain server, since everything will be perfectly replicated in the server cluster.

What characteristics do the VPS servers that we can find have?

Once we have seen the main differences between these two types of virtual servers, we are going to see what characteristics these VPS servers that we have talked about have. A very interesting aspect is the projects that we can carry out with these VPS, since their prices are usually really competitive.

web hosting

The main difference with a normal hosting server is that VPS servers offer more storage space, and as a general rule, data transfer is usually unlimited. This is ideal for setting up a web server, database server and providing access to a web very easily.

24×7 surveillance

This type of VPS servers offer control by the hosting staff and through tools available to the client for the monitoring and control of the systems 24 hours a day. Normally we have a console from where we can see if there is any kind of failure in the VPS, and in case of a hardware failure, they will take care of fixing it.

Backups

Being a virtual server, the hosting makes encrypted backup copies and keeps them safe. Of course, we advise you to also make a local copy of all the content of your VPS server. Another important aspect is that normally in VPS we have disks in RAID, so that, if one disk fails, the entire system continues to work correctly, and no data is lost.

Maintenance

Like a dedicated hosting server, VPS servers are also maintained by the hosting. One of the disadvantages with a Cloud server is that when maintenance is done on your server, your website may be down while said maintenance is being carried out. The servers in the Cloud have redundancy of disks, CPUs, RAM and network so that it is not noticed that an intervention is being carried out.

As you have seen, with a VPS we will have total control over the server, with the corresponding resources assigned (and contracted) by us. A VPS is the ideal solution for any user who wants to deploy a somewhat more complete project than a simple shared hosting. And also, we must bear in mind that we will have guaranteed resources that we do not share with other users.

Finally, we would like to recommend that you always choose to choose an SSD VPS, that is, it will not use hard drives, but will use solid-state storage. This will provide us with a better overall performance of the system, and, above all, if you are going to use it for web hosting, you will notice the difference. The negative part is that we will have less storage compared to a VPS with hard drives (at the same price), so depending on the use you give it, you will have to see what is best for you.
