Cloudflare

Cloudflare is far more than just a content delivery network (CDN). It acts as a protection and acceleration layer (edge) in front of the actual server infrastructure.


Core Concept

The intelligent edge: requests are processed at the data centre closest to the user. This enables massive protection against attacks (WAF, DDoS) and extremely fast load times through caching and global optimisation.

Assessment

  • Use case: Protecting business-critical websites, accelerating global APIs, and executing code directly at the edge (Cloudflare Workers).
  • Advantage: Market-leading DDoS protection, very easy to configure, and an excellent free base offering.
  • Limitation: Acts as a man-in-the-middle, which requires full trust in the provider; complex configurations can lead to hard-to-trace errors.
