Event driven design and serverless

on YouTube ↗25m

" summary

Claims a production event-driven, serverless pipeline solves dependency and downtime by switching from synchronous callbacks to event transfer state and per-event functions; implementation uses AWS Lambda, API Gateway, NoSQL with change streams, a publish/subscribe broker and a managed state machine to enrich and classify events. Caching fixes 80–90% of availability hits. Warns about cold starts, timeouts, concurrency limits and observed Lambda throttling; the ingestion→processing→distribution pipeline is deployed and operating at Groupe SeLoger.
