summary
Shows concrete architectures and outcomes: RabbitMQ (AMQP 0.9.1) powers Adidas Runastic leaderboard updates and a food‑delivery relay, queuing millions of events so spikes during the pandemic and Black Friday don’t drop requests. Demonstrates image‑resizing offload, database backups for thousands of DBs, and a 65‑million‑reader newspaper pipeline. Explains Quorum queues for HA, streams for multi‑consumer reads, priority queues, dead‑letter handling, MQTT and WebSocket bridges, and real migrations/federation patterns; classic queues are discouraged and the solutions are shown working in production.
