Microservices Development Cookbook

By: Paul Osman

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.

Securing containers


The advent of containers has solved many problems for organizations that are managing microservice architectures. Containers allow services to be bundled as a self-contained unit, and the software and its dependencies can be built as a single artifact and then shipped into any environment to be run or scheduled. Instead of relying on complicated configuration-management solutions to manage small changes to production systems, containers support the idea of immutable infrastructure; once the infrastructure is built, it does not have to be upgraded or maintained. Instead, you just build new infrastructure and throw away the old.

 

Containers also allow organizations to optimize their use of storage and compute resources. Because software can be built as containers, multiple applications can be running on a single virtual machine or piece of hardware, each unaware of the others' existence. While multi-tenancy has many advantages, having multiple services running on the same...
