Functional distributed systems beyond request/response
summary
Argues that replacing request/response with event-driven, append-only logs yields composable resilient services instead of fragile synchronous webs; shows concrete tooling (Kafka/Kinesis, Debezium/Kafka Connect, protocol buffers, gRPC, Kubernetes), patterns (database change capture, event sourcing), and a live comparison demo of a breakfast-order app plus a real migration that runs at scale (migrated a PHP monolith to Go/gRPC/Kafka serving ~100M users), demonstrating the approach actually works.
