Explore microservices in-depth and understand when to use them.

Scalability & System Design for Developers

In this module, we’ll explore microservices in depth and understand when to use them. Beyond that, learn about micro and macro architecture, strategies for migrating old systems, the role of Docker in this architecture, and technologies for implementing microservices.

An Introduction to Microservice Principles and Concepts

## New microservices
Creating a new microservice is very easy with Spring Boot.
A **build script** and a **main class** are enough, as shown in the example [simplest-spring-boot](https://github.com/ewolff/spring-boot-demos/tree/master/simplest-spring-boot). 

To further simplify the creation of a new microservice, a **template** can be created. The template only needs to be adapted for a new microservice. 

>**Settings** for the configuration of the microservices or for logging can be defined in the template. 

Thus, a template simplifies the creation of new microservices and facilitates compliance with macro architecture rules.

A particularly easy way to create a new Spring Boot project is to use http://start.spring.io/. 

The developer must select the build tool, the programming language, and a Spring Boot version. 

In addition, they can select different starters. Based on this, the website then creates a project that can be the basis for the implementation of a microservice.
