Nginx reverse proxy distributes incoming user traffic across heterogeneous application servers running Node.js, Python, Java, and Go simultaneously. The reverse proxy layer handles request routing, load balancing, and protocol translation, decoupling clients from backend language choices. This polyglot architecture enables teams to use the best language for each service while maintaining a unified entry point and simplified client communication. Fork this diagram on Diagrams.so to customize server counts, add health checks, or integrate SSL/TLS termination. Consider adding a load balancing algorithm specification and backend pool health monitoring for production deployments.
