Noble Demos - Cloudflare Demonstrations

Cloudflare overview

The Connectivity Cloud

Two problems break every internet-facing app: keeping it secure and keeping it fast everywhere. Cloudflare's answer is a single global network that solves both at the edge — before the request ever reaches your origin.

Network

Close to every user

330+ cities, one anycast network. The closest PoP answers — so latency stops being a geography problem.

One platform

Security and performance, same layer

WAF, DDoS, bots, caching, routing, and compute share one control plane. No bolt-ons, no drift between tools.

Dashboard + API

Change once, everywhere instantly

UI, API, and Terraform parity. A rule you ship propagates to all 330+ cities in seconds.

Scale

~20% of the web

of all web properties sit behind Cloudflare — including 80% of the top 50 genAI companies.

Get started

Add your domain to Cloudflare

5 minutes at your registrar. Point your nameservers to Cloudflare and your site runs on this edge.

~10 min hands-on No downtime No code changes

▸ DNS Setup Options Full Setup — Nameservers point to Cloudflare. Full DNS, full feature set.

Partial (CNAME) Setup — Keep your nameservers. CNAME a hostname onto Cloudflare's proxy:

www.example.com  CNAME
  → www.example.com.cdn.cloudflare.net

Limits: only A/AAAA/CNAME proxiable. No DNS-layer DDoS, no CF DNSSEC, Tunnel and Email Routing need manual setup.

▸ Proxy Status The magic Anycast toggle.

Proxied — traffic enters Cloudflare's Anycast network at the nearest of 330+ data centers. Origin IP hidden. WAF, cache, Bot Management, Workers all run here.

DNS-only — Cloudflare just answers the query and hands back your origin IP. No proxy, no protection.

Only A, AAAA, CNAME can be proxied. View DNS Records ↗

▸ Certificate Management Universal SSL (visitor → CF) is free, auto-renewed, and publicly trusted. On Full setup, covers root + first-level subdomains automatically.

Origin CA (CF → origin) is also free, valid for 15 years, and trusted by Cloudflare. Use Full (strict) SSL mode to encrypt both legs and validate your origin certificate. View SSL/TLS Settings ↗
