Microservices Development Cookbook

Overview of this book

Microservices have become a popular choice for building distributed systems that power modern web and mobile apps. They enable you to deploy apps as a suite of independently deployable, modular, and scalable services. With over 70 practical, self-contained tutorials, the book examines common pain points during development and best practices for creating distributed microservices. Each recipe addresses a specific problem and offers a proven, best-practice solution with insights into how it works, so you can copy the code and configuration files and modify them for your own needs. You’ll start by understanding microservice architecture. Next, you'll learn to transition from a traditional monolithic app to a suite of small services that interact to ensure your client apps are running seamlessly. The book will then guide you through the patterns you can use to organize services, so you can optimize request handling and processing. In addition this, you’ll understand how to handle service-to-service interactions. As you progress, you’ll get up to speed with securing microservices and adding monitoring to debug problems. Finally, you’ll cover fault-tolerance and reliability patterns that help you use microservices to isolate failures in your apps. By the end of this book, you’ll have the skills you need to work with a team to break a large, monolithic codebase into independently deployable and scalable microservices.

Running multi-container applications with Docker Compose


Services rarely run in isolation. A microservice usually connects to a data store of some kind, and could have other runtime dependencies. In order to work on a microservice, it's necessary to run it locally on a developer's machine. Requiring engineers to manually install and manage all the runtime dependencies of a service in order to work on a microservice would be impractical and time consuming. Instead, we need a way to automatically manage runtime service dependencies.

Containers have made services more portable by packaging the runtime environment and configuration with the application code as a shippable artifact. In order to maximize the benefits of using containers for local development, it would be great to be able to declare all the dependencies and run them in separate containers. This is what Docker Compose is designed to do.

Docker Compose uses a declarative YAML configuration file to determine how an application should...
