Top Microservices Courses with certification online

 Hello Java Programmers, if you want to learn Microservice architecture and looking for free Microservice resources like free online courses and books then you have come to the right place.

Earlier, I have shared the best Microservice courses for Java programmers to build Microservice using Java and the Spring framework, and today, I am going to share some free courses to learn Microservice in Java using Spring Boot and the Spring Cloud framework.

If you don’t know, Microservices is a modern architecture that goes along nicely with cloud computing and makes deployment, scaling, and even development easier.

It provides a new way to deploy your Java application where a monolithic Java application is broken down into multiple, small, independent Java application which can be developed, deployed, and tested independently.

There are several benefits of following Microservice architecture like, multiple developers can work on multiple processes simultaneously. The build and release process becomes easier as you are only deploying things that you are changing and so on.

Another great thing about Microservice is that it goes hand-in-hand with the cloud. They are easier to scale and often deployed using containers like Docker which makes the deployment easier which can also be automated using Kubernetes for further scaling.

With an increased push to moving towards Cloud-based Architecture, Microservice is getting a lot of traction and becoming popular every passing day and it has now become an essential skill for Java developers.

When it comes to developing Microservice-based applications in Java, the Spring framework offers the best solution to create, maintain, and deploy enterprise-scale Microservices. Microservices allow very large systems to be built up, from a number of small collaborating components.

If you look closely it follows the Spring model of component-based development. Microservice is built using a small process that collaborates to do what you indent do.

Spring also does the same where the application is made of small, collaborating components or Java classes, or Spring beans. This loosely coupled design offers many benefits which powered modern software development.

1. Developing Cloud-Native Apps w/ Microservices Architectures

This is another free Microservice course from Udemy which can be used to find the proper frameworks and tools to build your microservices architecture in Java. This course is created by Red Hat Inc, one of the patrons of JBoss and creator of RedHat Linux.

In this official Red Hat® training course, Burr Sutter, the Chief Developer Advocate for Red Hat, will give you a deep dive into the microservices architecture.

Here are key skills you will learn in this course:

1. Basics of executing a microservices architecture.

2. Learn how to deploy a variety of microservices frameworks through a DevOps pipeline.

This course is designed for programmers and developers who want to combine different frameworks and tools to build a Microservice architecture for their organization. It’s also great for anyone seeking an understanding of the OpenShift and Kubernetes tool and platform.

2. Master Spring Microservices with Spring Boot & Spring Cloud!

This is one of the best free courses to learn Microservice with Spring Boot and Spring Cloud on Udemy. This course is created by Karthikeyan T, author of a full-stack Java course that I have recommended in the past. In this free Microservice course, you will learn about the basics of Microservice architecture.

Once you understand the basics you will develop a mini Microservice App using Spring Boot and Spring cloud where you will create several services like Pricing Service, Inventory Service, Currency Conversion Service to build a Microservice architecture.

This course is great to gain some hands-on experience in developing Microservices for FREE.

If you already know Spring boot and a little bit of Spring cloud then you will learn quickly, but even if you don’t, you will still gain a lot of useful information for free of cost. I highly recommend this course to anyone who wants to learn Microservice in Java with Spring.

3. Develop a reactive Java microservice with ReactiveJ

This is another free Udemy course to learn Microservice in Java. The difference between the previous course and this course is that it uses ReactiveJ and RxJava to build Reactive Microservice in Java instead of Spring Boot and Spring Cloud.

In this course, you will learn the main concepts of reactive programming and we’re going to develop a reactive microservice with Java, ReactiveJ, and RxJava2. This course is suitable for beginners.

Here are the main things you will learn in this course

Reactive programming

JSR 340 and servlets 3.1 specification

advantages of reactive programming

non-blocking embedded Jetty

ReactiveJ non-blocking and asynchronous library

develop of asynchronous and blocking app with ReactiveJ

develop an asynchronous and nonblocking app with ReactiveJ and RxJava2

If you don’t know Spring Boot and Spring Cloud is not the only way to develop Micrserovde you also have other options like RxJava, Quarkus, MicroNaut, and much more. This free course is great to explore another option for building Microservice in Java.

4. Basics of Microservices [Free Udemy Course]

This is a more fundamental course than whatever we have seen so far. If you are a complete beginner to Microservice then I suggest you to should start with this free course.

This course is great to learn about what is Microservices, what benefits it offers, why you should be using Microservices, and how to design a highly available, fault-tolerant, secure, and scalable distributed system.

Here are key concepts you will learn in this free Udemy course:

What is Monolith Architecture?

What are the issues with Monolith & how it was addressed by more advanced patterns?

What is Service-Oriented Architecture and why SOA arrived?

Evolution of Microservices

What is Microservices? and Why Microservices?

Who should be using Microservices

What issues are addressed by Microservices et all?

This course also teaches you the difference between Monolith, SOA, and Microservice so that you can choose the right architecture for your application.

5. Building Scalable Java Microservices with Spring Boot and Spring Cloud [Free Coursera Course]

This is another free course to learn Microservices for Java developers with Spring Boot and Spring Cloud. The best thing about this course is that it is available in Coursera and it offered by Google Cloud Training, so you will be learning from the best in the Industry.

In this course, you will learn how to build Java applications using Spring Boot and Spring Cloud on Google Cloud Platform. You’ll use Cloud Runtime Configuration and Spring Cloud Config to manage your application’s configuration. You’ll send and receive messages with Cloud Pub/Sub and Spring Integration.

You’ll also use Cloud SQL as a managed relational database for your Java applications, and learn how to migrate to Cloud Spanner, which is Google Cloud’s globally distributed strongly consistent database service. You’ll also learn about tracing and debugging your Spring applications with Stackdriver.
