How Secure Serverless Microservice Platforms Completely Change Dev & Ops
summary
Compares Fly.io, Dapr and Calyx and shows a working Calyx demo that allocates stock without transactions: protobuf + Java + Maven generates entities, views and actions; event‑sourced order → order‑SKU → stock‑SKU flow emits events, runs with at least once delivery guarantees and idempotent handlers to avoid data leaks, and handles backorders and restocks correctly. Calyx hides DBs, message brokers and auth (mTLS, encrypted at rest, SOC2) so application code has no database connections in user code and the demo works end‑to‑end.
