During the course of this book, we will evolve a credit risk engine. It will not be a basis of many complicated aspects taken into account for creating algorithms of risk analysis. Rather it will be a very simple approach on 2-3 rules that will be simple to accept or reject for risk analysis. The focus of this application is not on how risk analysis is done, rather it is more focused on the factors such as how microservices should be designed, secured, communicate with each other, and so on.

While developing this kind of project, our development environment will include Spring Boot, and shipping microservices will be with Docker.
