Docker and IoT: securing the server-room with realtime ARM microservices

Why/what/how and demo of a scalable (over Swarm) real-time sensor network build on Docker ARM microservices and Raspberry Pi. Each sensor constantly samples the ambient temperature of individual server racks and sends a real-time alarm to the control room (LED display) when levels rise above normal levels. An anti-tamper motion sensor picks up tiny vibrations and alerts the admins when someone is performing unscheduled maintenance on the equipment. A custom made RGB LED display made by Pimoroni for Dockercon shows the status of up to 8 racks in real-time.
