This book is an end-to-end guide on how to split your monolithic Node.js application into several microservices. We'll cover some of the toolkits available, such as Express, Hydra, and Seneca, and create a simple microservice. We'll introduce you to continuous integration using Mocha to add a test suite, we'll use chai to test the HTTP interface, and we'll use nyc to see the test coverage.

We'll cover the concept of containers and use Docker to make our first deployment. We'll then use other tools, such as Docker Swarm, to help us to scale our service. We'll see how to do the same using Kubernetes, both locally and be using Google Cloud Platform, always using the same minimal microservice architecture and with minimal changes to the code.
