Choreography vs Orchestration in serverless microservices

on YouTube ↗46m

" summary

Compares event-driven choreography with centralized orchestration using concrete Google tooling: Google Workflows calling Cloud Functions, Cloud Run and external APIs, triggered by EventArc, defined in YAML and visualized in the console. Claims orchestration captures the business flow, surfaces which step failed, centralizes retries and supports the saga pattern for compensations, parallel branches, and executions up to one year. Shows demos and a GitHub repo. Notes tradeoffs: lost event flexibility, another service to operate, potential single point of failure, and harder local unit testing.
