Overview of this book

Google Cloud Platform is one of the three major cloud providers in the industry, exhibiting great leadership in application modernization and data management. This book provides a comprehensive introduction for those who are new to cloud development and shows you how to use the tools to create cloud-native applications by integrating the technologies used by Google. The book starts by taking you through the basic programming concepts and security fundamentals necessary for developing in Google Cloud. You'll then discover best practices for developing and deploying applications in the cloud using different components offered by Google Cloud Platform such as Cloud Functions, Google App Engine, Cloud Run, and other GCP technologies. As you advance, you'll learn the basics of cloud storage and choosing the best options for storing different kinds of data as well as understand what site reliability engineers do. In the last part, you'll work on a sample case study of Hip Local, a community application designed to facilitate communication between people nearby, created by the Google Cloud team. By the end of this guide, you'll have learned how to design, develop, and deploy an end-to-end application on the Google Cloud Platform.

How to make a canary release strategy with A/B testing

One of the strategies used when you want to release functionality without running the risk that an error in the new functionality interrupts the application is to expose the functionality to a small group of users in the live environment. Then, you observe its behavior and determine whether the behavior is as expected. If an error is detected, the previous functionality is simply exposed again to all users by reverting to the previous version. Otherwise, if its behavior is correct, the new functionality is exposed to more and more users until it reaches 100% of users. This is called the canary release strategy:

Static versus dynamic data considerations

When implementing the canary release strategy, it is important to understand the type of data that will be exposed by our new service, in order to control possible version update problems that may occur due to external...
