Without knowing it, we use CDNs on a daily basis (not to be confused with du Nord ). For example, the article you read is delivered by a CDN, so is also the case when you watch a video on YouTube. What is a CDN? A CDN or Content Delivery Network is an “intelligent” global network dedicated to the distribution of web Turkmenistan Email List content . It is an infrastructure made up of several networked servers located in different countries. These servers store content replicated from an origin server. To minimize the distance between each visitor and the server that hosts a website, each server in the WEB CDN infrastructure stores a cached version of the website content in multiple geographic locations.
CDN network infrastructure content Delivery Network infrastructure The main objective of a WEB CDN infrastructure is to deliver web pages with optimal loading time for the visitor. The operating principle of a CDN server therefore consists in making the content of a website available in several geographical locations at the same time (points of presence or PoP) . Each PoP is made up of multiple caching servers responsible for serving content to nearby visitors. A CDN infrastructure allows you to offer efficient global coverage to your visitors . For example, when the Internet user located in Montreal accesses your website hosted in Paris, a POP located in Canada delivers your web page.
How does a CDN Content Delivery Network work?
The POP located near the visitor allows the web page to be delivered much faster than if it came from the original server located in France. Content delivery with or without CDN infrastructure content delivery with or without CDN infrastructure As a publisher, if you want to improve the loading time and SEO of your website, setting up a CDN is an efficient and fast way to boost its performance. In addition to reducing web page load times, using a CDN also has the following advantages: improving site speed and user experience, reducing the response time of your website, improving referencing in each country, reducing the bandwidth of your web server.
reducing the load on your hosting server, enhanced protection against DDoS attacks and enhanced protection of your site, compatibility with an SSL certificate, a lighter configuration of your hosting server. The implementation of a CDN infrastructure, therefore, makes it possible to optimize the loading time of your website. It also improves SEO and security. Testing a CDN To provide a better experience for our visitors and optimize the SEO of our website, we have installed a CDN. You will find below our first feedback. Improved loading time (TDC) After considering creating our own CDN, we finally chose the one proposed by OVH for its presence on 3 continents and its 19 POPs. If you want to do a simple blog test, Cloudflare has a free plan.
What are the advantages of a CDN?

Setting up the CDN is a step that should not be neglected in order to get the maximum benefit from it. To take our example with the OVH CDN, the settings are made via the OVH manager. It consists of defining which resources the CDN should cache and for how long.
For example, it is possible to put a high caching timeout for resources that are not supposed to be updated frequently such as scripts, images, and stylesheets. Another advantage of the CDN delivered by OVH, there is no change of URL to make unlike the CloudFlare CDN . Our website is already hosted on OVH servers, the CDN is inserted before sending the request to the origin server. It allows you to send everything to the visitor: style sheets, scripts and images, all without any modification to the URLS. This eliminates redirects , the risk of deindexing following URL changes and 404 errors , etc. Simultaneous download It should also be noted that the principle of simultaneous download is another undeniable advantage of the CDN.
