CDN (Content-Delivery-Network or Content-Distribution-Network) is a large network of servers deployed in multiple data centers across the Internet or in other words a group of interconnected points geographically distracted that locally transmit and redistribute a large fraction of the Internet contents of your servers including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media and social network content in a transparent and performing way. The goal of a CDN is to serve content to end-users with high availability and high performance and also cache files that do not require a continuous update. (thing that a single server wouldn’t be able to provide due to the overload it could receive for the numerous requests of service from multiple servers).
Let make an example: If you have a nice blog or website (for eg located in California) visited by users from around the world (so not close to the original server) the request to upload the content of the site by one or more of your users (eg a user located in India) can take much longer time to cross the global Internet network and reach the server, resulting in long and sometimes inconsistent waiting times, in other words, an unsatisfactory user experience.


Many platforms provide activity time monitoring, page speed monitoring, transaction monitoring, server monitoring, and free tools that can test the speed of websites.

The most important metrics you should check during the test are:

  • Load Time
  • HTTP headers
  • Uptime
  • Third-Party domains


One of the first thing to check is the speed of your website. This metric can deeply increase or decrease sales or visit on your site. Nowadays people are less and less concentrated and always in hurry so, even 2 seconds more of delay can make a huge difference and can make you lose hundreds of users.


HTTP stands for “Hypertext Transfer Protocol” and it refers to how servers communicate and respond with another server by sending information about the client’s browser, request page, server, and more. It is important to understand if your server communicates in the same way and if there aren’t error in their request.


If the server is not running and starts to experience downtime, not being able to provide the services requested to their customers, the latter being unable to get the information they need, go to search for this information from another place.


You might have videos or content that are hosted by third parties. They can be images, plugins, JS files or videos that could slow down the loading of your website, influencing the speed of site loading.

Using a CDN can bring a lot of benefits to your site and some of which are:

  • cost reduction for bandwidth
  • performance improvement
  • high availability
  • most efficient web protection

All these benefits reflect in a positive way into your SEO ranking which is one of the most important things in these days if you want to have the chance to appear on the top results of Google Search and achieve your goals.


CDN can provide different services and each one can be more specific, for a different type of website.

In general, we can say that a good CDN has to have:

  1. Adequate control on how content is cached on your network.
  2. Minimize the bandwidth consumption and latency generate by geographical distance
  3. Be able to deliver all kinds of files, from small files like KB to heavy files like MB
  4. Provide security services for distributed denial-of-service (DDoS) protection
  5. Offer a good level of encrypted Internet transport (which helps speed up traffic sorting)
  6. Specific quality and security services for video content
  7. WAFs: is a firewall for HTTP applications. It applies a set of rules to an HTTP conversation. Generally, these rules cover common attacks such as Cross-site Scripting (XSS) and SQL Injection.
    (A WAF can be considered a reverse proxy, which is deployed to protect a specific web application or set of web applications).
