Choreography vs Orchestration in serverless microservices

on YouTube ↗38m

" summary

Compares three concrete patterns and shows working demos: Google Cloud Workflows orchestrates Cloud Run, Cloud Functions and external APIs (SendGrid via Secret Manager) with built-in OIDC/OAuth, retries (default 5 tries), callbacks and connectors; Eventarc + Workflows demo processes images through four functions (filter, labeler, resizer, watermarker) triggered from storage and it runs end-to-end; parallel BigQuery queries drop total time from ~60s to ~20s; samples and YAML/JSON workflow definitions are on GitHub and Speaker Deck.
