In Detail

Microservices architecture is a style of software architecture. As the name suggests, microservicess refers to small services. For a large implementation, this means breaking the system into really small, independent services. Alternative to monolithic architecture (where the entire system is considered as a single big, interwoven segment), microservices approach is getting more and more popular with large, complex applications that have a very long lifecycle, which require changes at regular intervals. Microservices approach allows this type of changes with ease as only a part of the system undergoes changes and change control is easy.

An example of such large system can be an online store—includes user interface, managing product catalog, processing orders, managing customer's account. In a microservices architecture each of these tasks will be divided and into smaller services. Also, these services will be further broken down into independent services—for user interface, there will be separate services for input, output, search bar management, and so on. Similarly, all other tasks can be divided in very small and simple services.

Style and approach

This book is a comprehensive guide to developing production-ready implementation of the microservices architecture with Node.js. Each chapter builds up on the earlier one creating a strong foundation on which you create your own microservice in a distributed environment.

It has become the preferred way of creating enterprise applications. Through this book, you'll discover the power of Node.js by writing fast and light microservices ready to ship in small Docker containers, making deployment and scaling quite enjoyable.You will be introduced to tools such as Seneca and PM2 to implement microservices with Node.js. We will help you understand and avoid common pitfalls faced while working with microservices. You will also learn to control your applications by getting to know the best tools for logging and monitoring.Upon completion of this book, you will understand the process of building high-quality microservices with a good test coverage, as well as the concepts of Node.js that are required to build microservices.
