Cloudflare

Cloudflare is more than a CDN; it is a global super-cloud. In 2025, Workers AI (Edge GPU inference) and R2 (Egress-free storage) are compelling reasons to build here.

When to Use

• Edge Compute: Cloudflare Workers start in <5ms globally. Perfect for APIs and Middleware.
• Storage: R2 is S3-compatible but has zero egress fees. Massive cost savings for data-heavy apps.
• Security: Zero Trust (Access) replaces corporate VPNs.

Core Concepts

Workers

V8 Isolate-based serverless functions. No cold starts. Write code in TS/JS/Rust/Python.

Durable Objects

Stateful storage at the edge. Allows coordination (e.g., waiting lists, chat rooms) globally without a central DB.
