Master Microservices with Spring Boot and Spring Cloud

This course introduces Spring Boot, Spring Cloud, and the Netflix OSS suite as a way of deploying highly resilient and scalable RESTful services and web applications.

There are two parts to this course – RESTful web services and Microservices

In the first part of the course, you will learn the basics of RESTful web services developing resources for a social media application. You will learn to implement these resources with multiple features – versioning, exception handling, documentation (Swagger), basic authentication (Spring Security), filtering and HATEOAS. You will learn the best practices in designing RESTful web services.

In the second part of the course, you will learn the basics of Microservices. You will understand how to implement microservices using Spring Cloud.
