The common patterns and practices of the microservice architecture and their application using the Clojure programming language.

About This Book

• Relevance of the microservice architecture and benefits of Clojure's functional and simple features to implement it.
• Learn best practices and common principles to avoid common pitfalls while developing microservices.
• Learn how to use Pedestal to build your next microservices, secure them using JWT, and monitor them using the ELK stack

Who This Book Is For

You should have a working knowledge of programming in Clojure. However, no knowledge of RESTful architecture, microservices, or web services is expected. If you are looking to apply techniques to your own projects, taking your first steps into microservice architecture, this book is for you.

What You Will Learn

• Explore the pros and cons of monolithic and microservice architectures
• Use Clojure to effectively build a reallife application using Microservices
• Gain practical knowledge of the Clojure Pedestal framework and how to use it to build Microservices
• Explore various persistence patterns and learn how to use Apache Kafka to build event-driven microservice architectures
• Secure your Microservices using JWT
• Monitor Microservices at scale using the ELK stack
• Deploy Microservices at scale using container orchestration platforms such as Kubernetes

In Detail

The microservice architecture is sweeping the world as the de facto pattern with which to design and build scalable, easy-tomaintain web applications. This book will teach you common patterns and practices, and will show you how to apply these using the Clojure programming language.

This book will teach you the fundamental concepts of architectural design and RESTful communication, and show you patterns that provide manageable code that is supportable in development and at scale in production. We will provide you with examples of how to put these concepts and patterns into practice with Clojure. This book will explain and illustrate, with practical examples, how teams of all sizes can start solving problems with microservices.

You will learn the importance of writing code that is asynchronous and non-blocking and how Pedestal helps us do this. Later, the book explains how to build Reactive microservices in Clojure that adhere to the principles underlying the Reactive Manifesto. We finish off by showing you various ways to monitor, test, and secure your microservices. By the end, you will be fully capable of setting up, modifying, and deploying a microservice with Clojure and Pedestal.

Style and approach

This book highlights the merits of the microservice architecture and its implementation with Clojure. Learn to implement microservices by migrating a monolithic application to a microservice-based architecture.
