Reverse Proxy
Domain: Internet & Web
🎯 Motivation
A server that sits in front of other servers, forwarding requests. Provides security, load balancing, and caching.
📋 Concrete Example
Reverse proxy: all requests go to proxy.example.com. Proxy forwards to backend1, backend2, or backend3. Users never see the backend servers directly. Security + load balancing + caching.
🔗 Analogy
A reverse proxy is like a building receptionist - all visitors go to reception first. Reception directs them to the right office (backend server). Visitors never know the actual office number. Security and organization.
