API Gateway & Reverse Proxy (Nginx + Spring Cloud Gateway) · Lesson

Path-Based Routing to Microservices

Use Nginx location matching to route different URL paths to different backend microservices behind a single entry point.

One Door, Many Services

In a microservice system, clients should hit a single host while Nginx fans requests out to the right service based on the URL path.

This keeps clients simple and hides the internal topology.

Routing decisions live in location blocks. Each matches a path pattern and proxies to a specific upstream.

location /users/ {
    proxy_pass http://users-service/;
}
location /orders/ {
    proxy_pass http://orders-service/;
}
