How does Eventarc differ from Pub/Sub?

Pub/Sub is a messaging service for publishing and subscribing to streams of messages. Eventarc is an eventing layer built on top of Pub/Sub (and Cloud Audit Logs) that adds event filtering, standardized CloudEvents format, automatic trigger management, and direct integration with 130+ Google Cloud event sources. Use Pub/Sub when you need raw message queuing; use Eventarc when you want event-driven triggers with declarative routing from cloud service events to specific destinations.

What event sources does Eventarc support?

Eventarc supports direct events from Cloud Storage, BigQuery, Firestore, and other Google services, Cloud Audit Log events from any GCP service that produces audit logs, Pub/Sub messages as a channel for custom or third-party events, and third-party providers registered through Eventarc's provider framework. For Cloud Audit Log events, you can filter by service name, method name, and resource type to trigger only on specific operations.

About This Tool

Eventarc is Google Cloud's eventing platform that routes events from over 130 Google Cloud sources, third-party providers via Pub/Sub, and custom applications to Cloud Run services, Cloud Functions, GKE services, and Workflows. It provides a unified model for event-driven architectures with filtering, delivery guarantees, and audit logging. This builder helps you configure Eventarc triggers with event type filters, path patterns, service account bindings, and destination configurations.

When to Use This Tool

•Creating triggers that route Cloud Storage object-finalize events to a Cloud Run service for automatic file processing
•Building Eventarc triggers that respond to BigQuery job completion events to start downstream data pipeline stages
•Configuring Cloud Audit Log triggers that fire when specific IAM or resource changes are detected for compliance monitoring
•Setting up third-party event routing from custom applications through Pub/Sub channels to Cloud Run destinations
