Cloudflare

Cloudflare is a global network for faster, safer apps — DNS, CDN, DDoS protection, WAF, Workers edge compute, and R2 storage. Features, use cases, and why it matters.

Overview

Cloudflare is a global network that sits in front of websites and apps to make them faster and safer. It handles DNS, CDN caching, DDoS protection, and edge compute (Workers), plus object storage and Zero Trust security.

Key Features

DNS and CDN with global caching
Automatic DDoS mitigation and WAF
Workers edge compute
R2 object storage
Zero Trust access controls

Best For

Anyone running production sites or apps that need performance, protection, and a reliable global edge.

Pricing Model

Freemium — a generous free tier, with Pro, Business, and Enterprise paid plans.

Strengths

Enterprise-grade security and speed are available even on the free tier, and the edge platform keeps expanding into full backend capabilities.

Limitations

The breadth of products has a learning curve, and advanced features or higher limits require paid plans.

Real Use Cases

Putting sites behind Cloudflare for DNS, caching, and DDoS/WAF protection.
Using Workers and R2 for lightweight edge logic and storage without standing up servers.

Why It Matters for Businesses

Cloudflare delivers security and performance that used to require a dedicated ops team — for free or near-free.
