A VPS or Private Virtual Server is a method that allows you to partition the resources of a physical server in multiple sections, all thanks to a special operating system that will manage virtualization. Each of these sections is installed a different OS, allowing work with each of these virtual machines as if it were a server independent of any other operating system that works on the same server, and all running at the same time. Put simply, a server is installed two or more operating systems and each of them is a separate VPS.
A VPS is a way to take advantage of the benefits of having a dedicated server at a much lower price, because instead of investing necessarily in the necessary infrastructure to have several servers, only one is invested and all the necessary ones are virtualized. Once the VPS are installed and configured, they can be accessed from the network through “Remote Desktop” or “SSH” sessions.
Working with information is always a very big responsibility. The information may be about the customers of a company, the necessary files and documents that make up a website, the inventories of products or even the accounting that a business manages. To save this information and of course, the computer systems with which the company will work, a server is always necessary where all these processes are centralized.
The costs of maintaining your own server go beyond the purchase of the equipment, you must also budget the costs of energy, cooling, maintenance, bandwidth on the Internet, electrical backup system and of course, the security required by the place avoid mishaps or theft of information.
Many companies necessarily require that investment and have their own server; However, there will be many businesses in the small or medium industry, which do not require something so advanced for their operation or simply that their administrative expenses do not allow them to do so for the time being. In view of that, the VPS servers have been created.
How Do VPS Servers Work?
Let’s talk about a typical case. Think of the following: Let’s suppose that we have 10 physical servers in a site and they are all working at the same time since they are indispensable, but if we verify the performance of each one we will notice that we are possibly not taking advantage of half of the available resources of each one (RAM, CPU, Hard Disk space ); even if we add everyone’s consumption of resources, we may realize that they could all work together on a single server if they were virtualized, each one becoming a VPS.
This practice has become somewhat imperative and necessary in most companies that require multiple servers. Failure to do so generates considerable waste.
From here comes an important question.
How Many VPS’s Can Be Installed On A Server?
It depends on several factors:
The physical characteristics of the server. Since each VPS will use resources of the server, it is necessary that it has good features that allow to run comfortably to each of the virtualized servers.
The operating system that will be used to virtualize. There are many virtualization systems and each one administers the resources of the equipment in different ways. Some are very simple and divide resources in a dedicated way, that is, if the server has 4 GB of RAM and two VPS with a capacity of 2 GB each are installed, when running both at the same time, there were no resources available for another VPS more, however this type of distribution of resources has fallen into disuse. Newer systems intelligently manage resources, thus allowing more VPS to be installed, taking into account that very rarely all VPS would need their maximum assigned capabilities at the same time.
The operating system that will be installed to each VPS. As you will know some OS require many more resources than others; for example Windows Server 2012 requires at least 512 MB of RAM, 32 GB of Hard Disk and 1.4 GHz of CPU, while one of the versions of Ubuntu Server only requires 128 MB of RAM, 1 GB of Hard Disk and 300 MHz of CPU .
The programs installed in each VPS. The software installed in each one will require certain resources from the VPS. The VPS administrator has to verify this important point.
Managing these factors correctly will allow the company to minimize the operative costs previously explained.
What Advantages Do VPS’s Offer?
In terms of operability, they provide us with the same benefits as a dedicated server, since the administrator can install and delete any software or data required.
- The resources available for a VPS are scalable from the virtualization system.
- It facilitates the backup of the entire server, even without the need to turn off the VPS.
- You can restart each of the VPS independently.
- You can virtualize resources such as network cards and therefore have more IP addresses.
The companies that offer Web Hosting services usually offer us Shared Hosting services, that is to say that our hosting account is coexisting in the same server with the accounts of other clients, which would limit our growth in case of requiring or increasing resources. that we have.
Another option offered by these companies is precisely to rent a VPS, which would allow us to completely manage the resources of our hosting account without reinstallations or reconfigurations, and all at the time we want, we are the administrators from our own server.
In this way, if you require more disk space or memory, we would only need to request it from our Web Hosting company and in a matter of minutes (depending on the technical support of the company) everything will be ready, without our website stopping or one minute.
Hiring a VPS in the cloud allows us to have a complete server without having more than just terminals in our business and with the ease of accessing it from any site that has access to the internet.
We recommend you to review the different plans offered by the companies, so you can choose the one that best suits you.
