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.

Introduction to Docker and Kubernetes

Before starting to explore the world of applications deployed in IaaS and CaaS services, it is worth familiarizing ourselves with some basic concepts in order to understand how the different technologies interact in an ecosystem of microservices in the cloud. Thus, we will start by reviewing what containers and Docker container images are, and what Kubernetes is.

What is Docker?

Docker is a set of platforms and services that allow us, through the virtualization of the operating system, to decouple the dependency of applications to a particular infrastructure. We are able to execute our applications through units called containers, which encapsulate the entire application, together with the necessary dependencies, so that the applications can function properly in any environment.
