Microservices is an architectural style in which large, complex software applications are composed of one or more smaller services. Each of these Microservices focuses on completing one task that represents a small business capability. These Microservices can be developed in any programming language. This reference guide consolidates the authors' experience of many projects and programs with customers, and insights from many hours of intense discussions with experts from client companies and consultancies. The book takes a holistic view of the Microservices Architecture, while also giving specific guidelines on how to establish and roll out future-state Microservices Architecture based on the methodology and approach documented in this reference guide. Software professionals interested in learning about Microservices and how to develop or redesign a monolithic application using Microservices can benefit from this book.
