Part I: Motivation and Basics
Part I explains what microservices are, why they are interesting, and where they are useful. Practical examples demonstrate the impact of microservices in different scenarios.
Chapter 1, “Preliminaries,” start to define microservices.
To illustrate the importance of microservices, Chapter 2, “Microservice Scenarios,” contains detailed scenarios illustrating where microservices can be used.
