A Content Delivery Network (CDN) is, in terms of the primary service it offers, a set of cache servers, placed at various strategic geographical points and containing copies of the same content for distribution to users located nearby.
When a user accesses a site without a CDN, they send queries to the server that hosts the site, called the origin server, which may be geographically remote from them. The request then goes through many Internet routes which can be lengthy depending on the distance to be travelled, slow and possibly congested.
The principle of a CDN is to act as an intermediary between users and the host and to issue the content from servers placed in various locations across the world, nearest to the users.
For the user, the CDN will behave just as the website would directly. For the host site, it will also behave more or less as a web user would. This usually allows you to implement a CDN solution without touching the host site.
The filling of a cache server is done as the result of a user’s first query: the user requests the content from the CDN which then requests it from the host server, delivers it to the user and caches it. Each new user close to the relay server accesses the content without the CDN needing to ask the origin server for it again, which has the effect of speeding up delivery.
In addition to accelerating distribution, the use of a CDN allows you to reduce the use of bandwidth from the host server. This reduction allows you not only to decrease the cost of bandwidth, but also to reduce the risk of overloading the host server and therefore to improve the delivery security of the site. For sites using a CDN, we talk about CDNised content.
The CDN replicates certain data from a website onto relay servers, located in the vicinity of Internet users, in order to improve loading times and therefore response times.
The company CDN Tech, created in 2004, is a French company which merged in 2016 with Ecritel of which it was a subsidiary for several years.
Thus, through its brand CDN Tech, Ecritel goes beyond hosting and outsourcing solutions, and offers a high added-value complement: integrating and managing solutions from the main operators of CDN as well as services of secure distribution of internet, mobile and video content.
With more than 14 years of expertise in improving web performance, CDN Tech is the most important independent precursor to CDN integration in the market.
Content acceleration solutions, initially considered as comfort tools, are now a prerequisite for High Availability & High Performance, as well as website security.

web sites with CDN
Using CDN is essential when you want to reach Internet users all over the world, whether for the deployment of sites and web applications or for downloading files. With more than 100,000 points of presence around the world distributed over twenty different operators, the CDN Tech solution allows you to gain performance, regardless of the location.
A performance-based load balancing of CDN networks is realized in real time for an ideal user experience
In the case of an e-commerce site for example, the response time, that is to say the loading time of the pages, is crucial, and the static contents are very numerous (photos, images, catalogs, videos , white papers, user guides, manuals and more).
However, the more the user is located far from the server's hosting place, the longer the response time is.
Thanks to the CDN, the loading speed is multiplied because the CDN is placed between the hosting site and your users around the world. It caches content when a user requests it, and distributes it in record time without using hosting servers, making your site much faster. Naturally, a fluid and responsive site multiplies the chances of turning visitors into buyers.
