Navigating the World of CDNs: A Comparative Guide to Cloudflare and Its Competitors

What is CDN & Why use a CDN?

CDN also known as Content Delivery Network or Content Distribution Network refers to the intermediary servers between the main server and the user. When someone searches a website for information, the information travels the whole distance between the server origin and the user. That’s why it takes time to load the information. CDN is like a copycat storage or server containing all the information the origin server has and is placed in different parts of the world for full coverage. When a user sends a request for a query, the origin server redirects the user to the CDN that is geographically closer to them. 

Using CDN has a large number of benefits. Some of them are as follows:

  • Lessen page load time
  • Lessen bandwidth costs
  • Increase content availability
  • Decrease web traffic to the main server
  • Improve website security by distributing load from the origin server to different CDNs
  • Improve user experience & website performance

 

What is Cloudflare CDN? 

Cloudflare CDN

Cloudflare is most well-known as a Content Delivery Network (CDN). It was founded in 2009 by Matthew Prince, Lee Holloway and Michelle Zatlyn to build a betterbuild better internet. Cloudflare acts as a reverse proxy by caching static content across various data centers located in different geographical locations to reduce the load on the main server.

FAQs

  1. Can I use Cloudflare CDN with other CDN providers or services?
  2. While Cloudflare CDN provides a comprehensive solution for content delivery and            website optimization, it can also be used in conjunction with other CDN providers or services. For example, some users may choose to use Cloudflare CDN for its security features while leveraging other CDNs for specific performance or geographic requirements.
  3. What is the limitation for Cloudflare free CDN?
  4. The free plan may limit advanced performance optimizations, security features, analytics insights, support resources, and Page Rules, but there’s no bandwidth limitation. Users should review features and limitations to ensure the plan meets their specific needs.
  5. How other CDNs exactly different from Cloudflare?
  6. The following two points can clear the debate:
  • Cloudflare is a pull CDN: The first request is sent to your server and then cached at that specific data center for future visitors in that area. Other CDNs frequently provide Push CDN, which allows you to preload their cache.
  • Cloudflare is a somewhat transparent CDN: It doesn’t use a separate CDN subdomain for cached files. It is cached during transit from your usual URLs. Cacheable (static) files are cached with their original URL, whereas dynamic files go directly through the reverse proxy.
