About This Architecture

Event-driven microservices pipeline on GCP Cloud Run uses Pub/Sub topics to decouple three compute services across isolated subnets in a VPC. Service A publishes to Topic A-B, triggering Service B, which publishes to Topic B-C, triggering Service C in a chain. This architecture decouples services, enables independent scaling, and provides reliable asynchronous communication across Cloud Run workloads. Fork this diagram on Diagrams.so to customize subnets, add error handling paths, or integrate Cloud Tasks for delayed processing.

How do I design an event-driven microservices architecture on GCP Cloud Run using Pub/Sub?

This diagram shows three Cloud Run services (A, B, C) connected via Pub/Sub topics in a VPC with isolated subnets. Service A publishes to Topic A-B, triggering Service B, which publishes to Topic B-C, triggering Service C. This pattern decouples services, enables independent scaling, and ensures reliable asynchronous communication.
