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.

Building auto-scaling clusters

With the advent of virtualization and the move to cloud-based infrastructure, applications can exist on elastic infrastructure designed to grow and shrink based on anticipated or measured traffic patterns. If your application experiences peak periods, you shouldn't have to provision full capacity during non-peak periods, wasting compute resources and money. From virtualization to containers and container schedulers, it's more and more common to have dynamic infrastructure that changes to accommodate the needs of your system.

Microservices are a natural fit for auto-scaling. Because we can scale separate parts of a system separately, it's easier to measure the scaling needs of a specific service and its dependencies.

There are many ways to create auto-scaling clusters. In the next chapter, we'll talk about container orchestration tools, but without skipping ahead, auto-scaling clusters can also be created in any cloud provider. In this recipe, we'll cover creating...
