What is a CDN? A Comprehensive Guide

What is a CDN and how does it work
What is a CDN?
A CDN is a network of servers that are distributed geographically and store copies of your content in their caches. When a user requests content from your website, the CDN delivers it from the server that is closest to the user’s location. This reduces the distance and time that the content has to travel from your origin server to the user’s browser.

Do you want to make your website faster, safer, and more SEO-friendly? If so, you should consider using a CDN or Content Delivery Network. A CDN is a service that stores and delivers your content from servers that are close to your users. This way, your users can access your content faster and more reliably.

How does a CDN work?

A CDN works by following a series of steps that optimize the delivery of content:

  • The user enters the URL of your website in their browser or clicks on a link that leads to your website.
  • The user’s browser resolves the domain name of your website using a DNS (Domain Name System) service that is integrated with the CDN. The DNS returns to the browser the IP address of the CDN server that is closest to the user.
  • The user’s browser connects with the CDN server and requests the content of your website.
  • The CDN server checks if it has the requested content in its cache. If it does, it sends it to the user’s browser. If it doesn’t, it requests it from the origin server and stores it in its cache for future requests.
  • The user’s browser receives the content from the CDN server and displays it to the user.

What are the benefits of using a CDN?

Using a CDN for your website has many benefits,such as:

  • Improving your website performance - A CDN can reduce the latency and bandwidth consumption of your website, making it load faster and smoother for your users. A faster website can improve your user engagement, retention, and conversion rates.
  • Increasing your website security - A CDN can help you protect your website from some common malicious attacks, such as DDoS (Distributed Denial of Service) attacks, which try to overload your origin server with fake traffic and take your website down. A CDN can filter and block the malicious traffic before it reaches your origin server, keeping your website online and secure.
  • Improving your SEO ranking - Search engines like Google use website speed as one of the criteria for ranking websites in their search results. A faster website can help you rank higher and get more organic traffic.
