We are talking about the service provided by the host who rents his IT infrastructure to you. The host puts at your disposal the servers of its datacenter to place your data there, which you then define how to access it.
To 100% guarantee the functioning of its servers 24 hours a day (level of service required for a professional presentation of your company on the Internet and particularly in terms of e-commerce) the hosting profession has become extremely technical. A continuous service guarantee implies a power supply that can be backed up to be autonomous for at least a few hours to a few days. The operation of the servers (especially the processors) generates a lot of heat which must be removed to the outside. Server cooling and its energy-consuming aspect have also become a subject of concern with regard to the environmental impact of a data centre.
It is also necessary to implement techniques allowing to change “hot” certain elements of the server to “repair” it without stopping it. It is also necessary to be able to permanently guarantee a good level of speed by managing the network load between several access providers.
The different types of hosting
There are four main types of hosting and we will specify them from the most expensive to the most affordable.
Cloud hosting: or “cloud”, the famous “cloud computing” very widespread in the advertising lexicon. This type of hosting consists of using the resources of several servers on the same network. It is a classic technical structure which corresponds to the needs of large operators: in the same set, we find the physical infrastructure, IT structure (files, databases, etc.) and applications (software, types of functions, user interfaces, etc.). In this coherent whole, everything is defined and controlled, which makes it possible to adjust resources according to your needs and to bill for the actual use of the service.
You rent one or more servers that you administer yourself. The dedicated server is a classic solution for companies that need physical resources, without having to have their own installation locally. It is the solution for the confidentiality of your data.
In terms of web, the dedicated server is recommended when you have peaks exceeding 4 to 5000 connections/day, or from 100,000 monthly visits. We are there on sites that are starting to generate audience regularly.
VPS Hosting – Virtual Private Server
We are going there on shared material resources. You are no longer alone on your server as in the previous (dedicated) case, you are hosted on a server whose hardware resources are shared equally with the other virtual servers present on this server. Your data is isolated in the same virtual machine dedicated to you. This VPS behaves like a dedicated server but allows you to save on the physical part.
it is the simplest and most affordable hosting. You rent a small sector on which you install your data. The server simultaneously hosts 50 to more than a thousand websites depending on the case. You only take care of the administration of your website, without needing to administer the server which is managed by the host.

It is the classic solution for small businesses and businesses that are just starting out and for sites with a “small” audience.
Host my website or blog
Now that we have done this technical overview of hosting, we will have to choose a host for your website. You will see that it is not really complicated, as long as you keep in mind the traps to avoid.
Be the direct client of the physical host. You must be personally the client of the physical host.
At first glance, it seems obvious. But in reality, we note that in very many cases it is not you who is the client of the host physical, but the IT service company you went through.
