Description
The common patterns and practices of the microservice architecture and their application the use of the Clojure programming language.
Key Features
- 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 whilst developing microservices.
- Learn how to use Pedestal to build your next microservices, safe them the use of JWT, and monitor them the use of the ELK stack
Book Description
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 the use of 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 can provide you with examples of how to put these concepts and patterns into practice with Clojure. This book will give an explanation for 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 quite a lot of ways to monitor, test, and safe your microservices. By the end, you’ll be fully capable of setting up, modifying, and deploying a microservice with Clojure and Pedestal.
What you’ll learn
- Explore the pros and cons of monolithic and microservice architectures
- Use Clojure to effectively build a reallife application the use of Microservices
- Gain practical knowledge of the Clojure Pedestal framework and how to use it to build Microservices
- Explore quite a lot of persistence patterns and learn how to use Apache Kafka to build event-driven microservice architectures
- Secure your Microservices the use of JWT
- Monitor Microservices at scale the use of the ELK stack
- Deploy Microservices at scale the use of container orchestration platforms such as Kubernetes
Who This Book Is For
You must have a working knowledge of programming in Clojure. Alternatively, no knowledge of RESTful architecture, microservices, or web services is expected. If you’re looking to apply techniques to your own projects, taking your first steps into microservice architecture, this book is for you.
