Building an IoT Cloud for the Healthcare Industry: How to Solve Networking
summary
Builds a portable IoT healthcare cloud that connects hundreds of private hospital networks and 100,000+ devices over WebSocket, TCP and HTTP, runs apps on Cloud Foundry and moves between OpenStack and AWS. Uses Cassandra, RabbitMQ and MariaDB with benchmarks — Cassandra — 2–3k messages/sec per VM, RabbitMQ several thousand msgs/sec, deploys ELK with Kibana protected by a CF auth plugin, and handles VPN scale with Cisco ASA >2000 VPN tunnels and 100.64.0.0/10 NAT plus per-customer proxy servers; architecture proves workable and migrates to AWS using a virtual firewall.
