A Small Orange Review


Hosting, a term very common in the “web” vocabulary. However, we find that few people really know what it is. Do you know exactly where your website or blog is hosted? Who is your physical host? What are the conditions of this service and what does this entail for you? What are you really owning?

From experience, we find that these elements are very often ignored, while in fact, the hosting of your data is an extremely important element.

Web Hosting: What is it?

A / Accommodation: what are we talking about

Provision of materials and services

We are talking about the service provided by the host who leases you its IT infrastructure. The host puts at your disposal the servers of his data center to place your data, which you then define how to access it. The services offered differ depending on the use you want to make of your server (s): server of your company (with all your professional files, your programs used for your commercial or administrative tasks …), application server (to work remote for example …) or web server to install your site (s) Internet.

The Datacenter

This is the last case that interests us here: you read these lines because the association Info-Web is hosted on a server for the web, so accessible by everyone from your browser.

To ensure 100% operation of its servers 24/24 (level of service required for a professional presence of your company on the internet and particularly in the field of e-commerce) the job of host has become extremely technical. A guarantee of continuous service implies a power supply that can be rescued to be autonomous at least a few hours to a few days, anti-burglar, anti-immersion, fire and automatic extinguishing systems, air filtration, control of humidity, but also anti-piracy …

The operation of servers (especially processors) generates a lot of heat that must be evacuated to the outside. The cooling of servers and its energy-consuming aspect has also become a subject of concern with regard to the environmental impact of a data center.

We must also implement techniques to change “hot” some elements of the server to “fix” without stopping. It is also necessary to be able to guarantee a good level of flow at all times by managing the load of the network between several providers.

In short, without going into detail, remember that they are real data factories that are in million euros. For example, the company OVH, a leading global French host (top 5) claims more than 27 data centers for more than 300,000 active servers.

B / Who can claim to be “host”?

The “physical” hosts

As we have just seen, these datacentres are the physical (or “real”) hosts of your data. For example, our association Info-Web is hosted by the company O2switch, host French who will celebrate its 15th anniversary in 2018, whose datacentre is located next to Clermont Ferrand. It is therefore from an Auvergnat server that you consult these lines.

IT and web service companies

By extension many service companies offer hosting services, without themselves being the physical host. They rent a server or servers from a physical host and you “sublease” the accommodation, taking their margin in passing. Legally, this is not a problem because they do not claim ownership of the datacentre.

Commercially, they play on the ambiguity and lack of technical information of their customers to suggest that they have a “great” technical mastery. Host, it’s serious …

We often see advertisements of IT service companies or “web agency” who do not hesitate for a moment to claim to host … When we know the cost of a datacentre, it makes you smile. On the other hand, the consequences for your company of this economic model will not make you laugh at all … (detail on the paragraph “Being the direct client of the physical host”)

C / The different types of accommodation

There are four main types of accommodation and we will specify them from the most expensive to the most affordable.
