Cloudflare Workers excel at edge computing with instant cold starts and global distribution. When you need real-time features, you'll typically set up Durable Objects for state management, WebSocket handlers for live updates, and custom authentication. RedwoodSDK handles these patterns with React server components and built-in real-time features while generating standard Cloudflare Workers code.
