Cloudflare Foundations

Cloudflare is one of the most widely used edge platforms today: it puts CDN, DNS, DDoS protection, a WAF, caching, image processing, and serverless compute behind a single control plane, and once a domain is on it, speed, security, and operational cost often all improve at once. This course is organised in the order you would actually work in. You create an account, add a domain, and take over its DNS; then you understand how edge caching and smart placement decide your hit rate; then you harden the setup layer by layer with TLS certificates, the WAF, and rate limiting; and finally you reach for the serverless side of the platform — Pages, Workers, R2, and Workers KV — before closing with the analytics you need to judge whether any of it worked. By the end you should be able to move a site onto Cloudflare from scratch and explain why each setting is the way it is.
