Practical Microservices

Overview of this book

<p>A microservice architecture helps you build your application as a suite of different services. This approach has been widely adopted as it helps to easily scale up your application with reduced dependencies. This way if a part of your application is corrupted, it can be fixed easily thereby eliminating the possibility of completely shutting down your software. This book will teach you how to leverage Java to build scalable microservices. You will learn the fundamentals of this architecture and how to efficiently implement it practically.</p> <p>We start off with a brief introduction to the microservice architecture and how it fares with the other architectures. The book dives deep into essential microservice components and how to set up seamless communication between two microservice end points. You will create an effective data model and learn different ways to test and deploy a microservices. You will also learn the best way to migrate your software from a monolith to a microservice architecture.</p> <p>Finishing off with monitoring, scaling and troubleshooting, this book will set a solid foundation for you to start implementing microservices.</p>

Summary


In this chapter, we discussed the principles of communication between microservices and various methods of communication such as synchronous or asynchronous, and communication patterns such as choreography and orchestration. We have seen the example of event-based messaging and discussed various use cases and ways of doing it. REST can be used in both types of communication: synchronous and asynchronous. There are some tools to handle both type of communication. It entirely depends on the situation and the needs of the specific project to choose one pattern over the other. In the next chapter, we will discuss how to secure the microservices with an example of our credit-scoring microservice.
