Deep dive into fundamental knowledge about microservices and background information about the concepts behind the microservices architecture approach.

Microservices Architecture

In this module we’ll learn about microservices in depth and understand the reasons for using and not using microservices. We’ll also learn about micro and macro architecture, strategies for migrating old systems, the role of Docker in this architecture, and technologies for implementing microservices like Spring Boot and Go.

After this module, you’ll be better equipped to implement microservices.

An Introduction to Microservice Principles and Concepts

# The Spring framework and the Java community 

The Spring Framework has long been part of the Java community. It has a broad set of features covering most of the technical requirements of typical Java applications. [Spring Boot](https://projects.spring.io/spring-boot/) facilitates the use of Spring.

A minimal Spring Boot application can be found in the directory simplest-spring-boot of the project https://github.com/ewolff/spring-boot-demos.

## Java code

The Java code from the project shows how Spring Boot can be used.


In this lesson, we'll be starting the discussion about the Spring Boot framework.
