This diagram shows a microservices architecture with Nginx acting as a reverse proxy load balancer across 3 server nodes running Docker containers of a Node.js application tier that communicates with a Redis cache and MongoDB database hosted on MongoDB Atlas, with the user interface layer running AngularJS applications that make API requests to the middle tier.
