What is VPS? A virtual private server (VPS) refers to a part of a physical server, although it has an independent operation, despite sharing this material server with other virtual servers. Therefore, a VPS is halfway between a dedicated server and a shared hosting, since it works as a private machine for a client, but shares physical space with other VPS.

A VPS, although similar to Cloud Hoisting, is not the same. We will explain this later.

How does VPS work?

As we have already mentioned in the definition, VPS is part of a physical server divided into different virtual servers. This partition allows each VPS to work for a client as if it were a single machine, with its hard disk, RAM, and transmission speed, among other aspects. However, the real server is shared with other clients of the rest of the VPS hosted in it.

Therefore, the operation of VPS is independent, so it runs as a dedicated server, and all its resources are allocated to specific clients. Moreover, as the physical server is shared with other virtual servers, a VPS is cheaper than a dedicated server.

VPS servers were born around 2001 when some hosting providers started to offer virtual machines using FreeBSD, LinuxVserver, and OpenVZ technology. 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, offer servers with less capacity using a single physical machine. When the client hires it, he gets the access data to one of those virtual servers.

The customer must configure his server from scratch, including the operating system he wants, although VPS providers make this task much easier since we can choose from the administration console which operating system to install. 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 resources and a dedicated server where we will have the whole server for us and our project. A VPS is usually chosen for websites with a medium-high level of traffic that exceeds the shared hosting plans.

What are the benefits of a VPS server?

VPS servers are reasonably priced and affordable while offering more power and control as if they were a dedicated server.

A VPS has a series of benefits that we will explain below:

It is customizable: just like a dedicated server, a VPS server can be customized to install your operating system. With which you can fully customize the applications and functions installed on the server such as MySQL or PHP. This allows them to be adapted to the needs of the website.

It is private: in this type of server, since the IP is not shared as well as the operating system, there is no possibility that the rest of the websites with which the server is shared can see or access your files in any way.

You have complete control: after an installation, it is usually necessary to restart the server. For VPS, you can restart at any time without affecting the remaining websites installed on the server in another VPS.

You have dedicated resources: by having your dedicated RAM, no other website you share the server with will be able to use your part of the available memory space. So there will be no instability in the bandwidth capacity.

It is easily scalable: due to the characteristics of this type of server, it is easy and fast to increase its capacity at the time it is needed for your website. Likewise, if you do not need all the contracted capacity, it could be reduced as well.

Good quality/price ratio: due to the advantages offered by the VPS server, which are practically the same as a dedicated server but at a much lower price, together with its scalability options adapted to the needs of each user, this type of service becomes the best option for your website.

What are the disadvantages of a VPS Server?

The main disadvantage of VPS over shared hosting is the price.

A VPS will mean paying a higher price not only for the extra resources, but to the base price you will have to add three additional costs: the management panel (cPanel or Plesk license), the cost of the server administration service, and the space for the backups, although this will depend on the offer of each provider.

More advanced knowledge of configuration and administration of virtual servers is required being ideal for projects with specific requirements, but not recommended for a simple project or people not specialized in the subject.

When to use a VPS or switch from shared hosting to a VPS?

Before making any decision, we must evaluate the real needs that your web project faces. Once examined, you can make the choice to switch to a specific server.

Due to the difficulty in measuring the resources that you will need when starting a web project, many people start with shared hosting, being a very good option.

When the project grows and it is necessary to switch to a service with more resources, one of the most common choices is to switch to VPS, although this is not always the best choice.

The choice will depend on the volume of resources needed by the project, but in general, it is only recommended to move to a VPS if it is necessary to install or run applications at the server level or the traffic volume is high for a single website.

When to switch from a VPS to a dedicated server?

Although VPS servers are scalable and offer many advantages in terms of resources compared to shared hosting, we must bear in mind that it is still only a part of the resources or space that we have at our disposal from the physical server.

In this case, if your project is really big and you have a high volume of traffic, your VPS may need more resources and therefore our hosting provider will offer us the next alternative, which is a dedicated server.

When to switch from a dedicated server to a VPS

Dedicated servers offer all guaranteed resources, plus superior performance to other servers, which requires advanced knowledge to obtain maximum performance, coupled with a higher cost than a VPS server.

One of the reasons that would lead you to move to a VPS could be that you currently have more resources than we need, although in that case, you should study the possibility of a VPS

But for large projects and a greater need for increased capacity, a dedicated server may be the best option.
