Google PubSub Topic

Leave Feedback

Introduction

In a PubSub model, any message published to a topic is immediately received by all of the subscribers to the topic. PubSub messaging can be used to enable event-driven architectures, or to decouple applications in order to increase performance, reliability and scalability.

Setup

To set up the OpsRamp Google integration and discover the Google service, go to Google Integration Discovery Profile and select Topic.
