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.

Using Thrift


JSON and HTTP are simple, straightforward solutions for data transportation and definition that should serve the purposes of many microservice architectures. If you want type safety and often better performance, however, it can be worthwhile to look at binary solutions such as Thrift or gRPC.

Apache Thrift is an interface definition language (IDL) and binary transport protocol invented at Facebook. It allows you to specify APIs by defining the structs (which are similar to objects in most languages) and exceptions that your service exposes. Thrift interfaces defined in the IDL are used to generate code in a supported language that is then used to manage the RPC calls. Supported languages include C, C++, Python, Ruby, and Java. 

The benefits of a binary protocol such as Thrift are primarily improved performance and type safety. Depending on the JSON library used, serializing and deserializing large JSON payloads can be quite expensive and JSON does not have any type system that...
