What is Cloudflare?
Cloudflare is a global network that speeds up and protects websites and runs code at the edge.
📖 Key ideas
- It sits between visitors and your server as a reverse proxy.
- Its data centres in hundreds of cities serve content close to users.
- Main services: DNS, CDN caching, security (WAF, DDoS), and Workers.
- A free plan covers DNS, CDN and basic protection for small sites.
- "The edge" means servers near the user rather than one central server.
💡 Real-life example: Like a chain of local branch offices: customers visit the nearest branch instead of travelling to head office.
