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.

Introduction


Now that you've had some experience breaking a monolith into microservices, you've seen that many of the challenges exist outside the monolith or service code bases themselves. Exposing your service to the internet, controlling routing, and building in resiliency are all concerns that can be addressed by what are commonly called edge services. These are services that exist at the edge of our architecture, generally handling requests from the public internet. Luckily, because many of these challenges are so common, open source projects exist to handle most of them for us. We'll use a lot of great open source software in this chapter.

With the recipes in this chapter, you'll learn how to use open source software to expose your services to the public internet, control routing, extend your service's functionality, and handle a number of common challenges when deploying and scaling microservices. You'll also learn about techniques for making client development against services easier...
