Spring Boot Microservices with Spring Cloud Beginner to Guru (Udemy.com)

Microservices are all the buzz in the industry right now.

Building a microservice is not just a matter of using RESTFul APIs.

Microservices are much MUCH more than that.

In this course you will learn that Microservices are an architectural style. The allow companies to achieve massive scale while maintaining a high degree of flexibility. 

This course goes beyond simple RESTful APIs and explores microservices as an architectural style.

** What Students are Saying about the Course **

5 STARS Great course, you can be sure about it. If you're fairly new to the java world and spring framework, I highly suggest to follow Spring Framework from beginner to guru (the teacher is always John). In my experience I can tell you that after the first course, I managed to progress in my career twice, with praises of my colleagues and managers. The content of both courses is very well explained and easy to learn. If you want to stand out, definitely this course worth the money.

5 STARS Very good course on microservices with Spring! It gave me a good starting point for the upcoming task at my work! 5* all the way for John!

5 STARS I like this course a lot! It's exactly what I needed after some experience with Spring Boot, to go to the next level. A lot of applications are presented, giving the opportunity to exercise what you've learned. The assignments are also very welcomed.

5 STARS Very VERY good content, well structured approach and clear explanations. Very enjoyable and educative. I'm even picking up a few techniques / frameworks I hadn't really used before.

About the Course

Traditionally, large enterprise class applications were developed as large monolithic applications.

The Spring Framework started as an alternative to J2EE (now JEE) for building these large monolithic enterprise applications.

As the industry evolved to favor microservices over monoliths, the Spring Framework and Spring Boot evolved also.

The Spring Framework gives you a battle-tested enterprise grade framework for building applications.

Spring Boot and Spring Cloud are tools specifically for the development of microservices using the Spring Framework.

Microservices present a unique set of challenges over monoliths. Spring Boot and Spring Cloud help you overcome these changes.

• What are these challenges that microservices have, which traditional monoliths do not?

• Is it okay for microservices to share databases?

• How do you coordinate business logic across a series of microservices?

• How do you manage transactions across serval microservices with different databases?

To explain these questions, in this course you get to explore a traditional Spring Boot monolith type of application. (Along the style of Spring Pet Clinic).

We will then re-create this monolithic application using a set of microservices.

You get to see, step by step how to build 3 different microservices.

Microservices are much more than just having a set of RESTFul APIs. Microservices frequently use asynchronous messaging systems, which is fully covered.

While the Spring Framework and Spring Boot are the tools you use to construct Microservices, Spring Cloud provides the tools to deploy microservices.

You get to see the latest tools in Spring Cloud for deploying Spring Boot Microservices into a distributed (or cloud) environment.

In 2018, Netflix announced several core projects to Spring Cloud were entering maintenance mode. Meaning no new development would be done on these projects.

Thus, in December of 2018, the Spring Cloud Team recommended several key replacements:

Previous               Replacement

Hystrix         -->      Resliience4J

Ribbon         -->     Spring Cloud Load Balancer

Zuul 1           -->     Spring Cloud Gateway

Archaius 1    -->    Spring Cloud Config

Therefore, the recommend replacements are covered in this course.
