Eventarc for event routing in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Eventarc in Google Cloud?

Eventarc is a service that routes events from various sources to Google Cloud services, enabling event-driven architectures.

beginner

How does Eventarc deliver events to targets?

Eventarc delivers events using Cloud Pub/Sub as the transport layer to trigger services like Cloud Run, Cloud Functions, or Workflows.

What is a trigger in Eventarc?

A trigger defines which events to listen for and where to send them. It connects event sources to event consumers.

Name two common event sources supported by Eventarc.

Cloud Audit Logs and Cloud Storage are common event sources that Eventarc can listen to for routing events.

Why is Eventarc useful for building serverless applications?

Eventarc simplifies connecting events to serverless services, enabling scalable, loosely coupled, and reactive applications without managing infrastructure.

What does Eventarc use to transport events internally?

A Cloud Functions

B Cloud Storage

C Cloud SQL

D Cloud Pub/Sub

Eventarc uses Cloud Pub/Sub as the messaging layer to transport events reliably.

Which of these can be a target for Eventarc events?

A Cloud Run

B Cloud Storage Bucket

C Cloud SQL Database

D Cloud DNS

Cloud Run is a supported target for Eventarc events to trigger serverless containers.

What is the role of a trigger in Eventarc?

A To define event filters and destinations

B To store event data

C To manage user permissions

D To create virtual machines

Triggers specify which events to listen for and where to send them.

Which event source is NOT typically supported by Eventarc?

A Cloud Audit Logs

B Cloud Storage

C Cloud SQL queries

D Custom events via Pub/Sub

Cloud SQL queries are not event sources for Eventarc; it supports audit logs, storage, and custom Pub/Sub events.

Eventarc helps build applications that are:

A Monolithic and stateful

B Event-driven and serverless

C Manual and infrastructure-heavy

D Static and batch-only

Eventarc enables event-driven, serverless applications that react to events automatically.

Explain how Eventarc routes events from sources to targets in Google Cloud.

Think about how events flow from where they happen to where they are processed.

Describe why using Eventarc is beneficial for serverless application design.

Consider how Eventarc helps developers focus on code, not servers.
