Nginx
Domain: Internet & Web
🎯 Motivation
A popular web server and reverse proxy. Handles high traffic efficiently. Used for load balancing and serving static files.
📋 Concrete Example
Nginx: receives 10,000 requests/second. Serves static files (images, CSS) directly - fast. For dynamic content, forwards to the backend application. Also load balances across multiple backend instances.
🔗 Analogy
Nginx is like an efficient traffic cop - they handle simple requests (static files) themselves instantly. Complex requests (dynamic content) are forwarded to specialists (backend). They also direct traffic to less busy lanes (load balancing).
