Higher order infrastructure: from Docker basics to cluster management
summary
A polyglot app (Python voting, Java worker, Node.js results) is packaged into containers and deployed across a five‑node cluster using Docker Machine, Docker Swarm and Docker Compose with Consul for discovery. Redis buffers votes, a worker migrates them into Postgres, and an engine x proxy automatically updates routing by watching swarm events. The demo shows zero‑IP deployment, overlay networking, TLS for swarm events, and a live scale from one to four result instances with traffic served successfully.
