Presented By: Agnibhas Chattopadhyay and Saurabh Suresh Dhotre. The presentation introduces Google Cloud Pub/Sub, a messaging service that provides durable message storage and scalable delivery. It also discusses Spring Cloud GCP, an open source project that integrates Spring applications with Google Cloud Platform services like Pub/Sub to reduce boilerplate code. The presentation demonstrates how to get started with Spring Cloud GCP Pub/Sub modules and includes a demo of a sample application.

4. ● Cloud Pub/Sub is an asynchronous messaging service.
● It helps your tools send, receive, and filter events or data
streams.
● It gives you durable message storage, scalable in-order
message delivery.
● It offers consistently high availability and performance at any
scale.
● Pub/Sub runs in any Google Cloud region in the world.
Introduction

5. The aim of developing Spring cloud GCP is use Spring Framework on
GCP as easily and seamlessly as possible.
“The Spring Cloud GCP project makes the Spring Framework a
first-class citizen of Google Cloud Platform (GCP)”
This is a collaborative effort from Google and Pivotal to bring the
goodness of Spring into the GCP and in doing so, cut down on the
boilerplate code.

6. Features
Spring Cloud GCP Pub/Sub
It has modules for sending messages to Pub/Sub topics and receiving messages from
Pub/Sub subscriptions using the Spring Framework. You can use these modules
independently or combine them for different use cases:
Spring Cloud GCP Pub/Sub Starter, lets you send and receive messages using helper
classes.
Spring Integration Channel Adapters for Pub/Sub, let you connect Spring Integration
Message Channels.
Spring Cloud Stream Binder for Pub/Sub, lets you use Pub/Sub as messaging
middleware in Spring Cloud Stream applications.

7. Get started with Cloud Pub/Sub
There are multiple ways to get started with the GCP
implementation
● Build and deploy the Spring boot Java application from
Cloud shell without ever leaving the browser
● Deploy Spring boot App to App Engine
● Deploy Spring boot app to Google Kubernetes Engine (GKE)
