Global network security, CDN, Workers edge compute, and AI Gateway in one platform.
Technical Overview & Architecture
Cloudflare is a globally distributed cloud platform operating one of the world's largest networks — spanning 300+ cities across 100+ countries — providing CDN, DDoS protection, DNS, WAF, Zero Trust security, and edge compute (Cloudflare Workers) as integrated services. Over 20% of all internet traffic passes through Cloudflare's network, giving it unparalleled visibility and threat intelligence. Cloudflare Workers is a V8-based JavaScript/WebAssembly edge compute platform that runs code at the location physically closest to each user from 300+ data centers simultaneously — eliminating traditional origin server cold start latency. Workers KV, R2 (S3-compatible object storage), D1 (SQLite-compatible edge database), and Durable Objects (stateful serverless) give Workers applications a complete data layer. Cloudflare's AI Gateway (2023) is a transparent proxy for AI API calls (OpenAI, Anthropic, Hugging Face) that adds caching, rate limiting, spending controls, and observability to LLM requests without code changes. Cloudflare Workers AI provides serverless inference for open-source models (Llama, Whisper, Stable Diffusion) running directly on Cloudflare's GPU-equipped edge nodes.
