Implementing Event-driven Microservices

on YouTube ↗58m

" summary

Covers concrete choices and tradeoffs: uses domain‑driven design to pick service boundaries, advocates event sourcing + CQRS for eventual consistency, and explains sagas and compensating actions with an orchestration-over-choreography recommendation. Mentions Kafka and cloud message‑bus options, snapshotting to avoid replay cost, and failure scenarios (partial commits, rollbacks, visibility). Expect practical patterns, code‑level implications, and operational caveats rather than high‑level rhetoric.
