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.

Different flavors for different situations

Both Google App Engine and Cloud Functions have different options for the different workloads that we may wish to implement. In this section, we will review the different options and consider when to use each one.

HTTP functions

HTTP functions are functions that can trigger process executions through HTTP calls, such as calls from a backend service to a cloud function. By default, and for security reasons, when a cloud function is deployed, it requires authentication from the consumer. To avoid this type of behavior, a cloud function can be deployed from the GCP console by selecting the Allow unauthenticated invocations option or by adding the allow-unauthenticated flag if the Google Cloud SDK is used. It is important to note that only cloud functions that act as public APIs should allow calls without authentication; the other APIs should always have both authentication and authorization from the consumer.
