Cloudflare Workers Platform

Cloudflare Workers is a serverless execution environment that allows developers to deploy JavaScript, TypeScript, Rust, C, and Python code to Cloudflare edge network in over 300 cities worldwide, running code milliseconds away from end users. Launched in 2017 by Cloudflare (founded in 2009 by Matthew Prince, Lee Holloway, and Michelle Zatlyn), Workers processes over 50 million requests per second at peak. Key features: edge computing (code runs at the nearest Cloudflare edge location to the user, reducing latency to under 50 milliseconds globally without cold starts). Isolate-based runtime (uses V8 isolates instead of containers or virtual machines, enabling near-zero startup time, high density with thousands of isolates per server, and sub-millisecond cold start). Multi-language (JavaScript, TypeScript, and WebAssembly including Rust, C, C++, Go, and AssemblyScript compiled to WASM, plus Python via Pyodide). Workers KV (global, eventually-consistent key-value store for configuration data and session state with sub-50ms reads from any edge location). Durable Objects (strongly-consistent, stateful objects with global uniqueness for real-time collaboration, counting, rate limiting, and game state). D1 (SQLite-based serverless SQL database running at the edge with global read replicas). R2 (S3-compatible object storage with zero egress fees, integrated with Workers for file processing). Queues (managed message queues for asynchronous task processing and service decoupling). Databases via Hyperdrive (connection pooling and caching for existing PostgreSQL databases including Neon, Supabase, and AWS RDS). Cron triggers (scheduled execution of Workers at specified intervals). Wrangler CLI (command-line development tool for local development, testing, and deployment). Workers AI (LLM inference at the edge with models including Llama, Mistral, and custom fine-tuned models).
