Cloud Pub/Sub requires a couple of options to be completed prior to successful deployment. In the Cloud Console, Cloud Pub/Sub can be accessed under the Big Data menu option.

Cloud Pub/Sub can be used in a wide variety of use cases, the most common of which are listed below:

Integration of Pub/Sub with other Google Cloud products

Monitoring, Alerting, and Logging: Supported by Monitoring and Logging products.

Authentication and IAM: Pub/Sub relies on a standard OAuth authentication used by other Google Cloud products and supports granular IAM, enabling access control for individual resources.

APIs: Pub/Sub uses standard gRPC and REST service API technologies along with client libraries for several languages.

Triggers, notifications, and webhooks: Pub/Sub offers push-based delivery of messages as HTTP POST requests to webhooks. You can implement workflow automation using Cloud Functions or other serverless products.
