Our take

Based on the ratings of 6,130 students, a sample of their written reviews and the syllabus, as the course stood in October 2025. No course pays to be reviewed.

Infybuzz Learning built this as a short, practical pass through the Spring Cloud pieces that sit around a Spring Boot app. It opens with monolith versus microservices, then builds two small services, one for students and one for addresses. From there it adds OpenFeign, Eureka, LoadBalancer, API Gateway, Resilience4j, Zipkin tracing and Config Server. The whole thing runs about 4 hours over 68 lectures. The level says beginner, but the requirements are Java and Spring Boot, and one reviewer says plainly it is not for very beginners.

Students like how quick and direct it is. Reviewers call the teaching clear and to the point, and one says they came away seeing end to end how Spring Cloud is used in real time. The complaints are steady and mild. Some annotations and dependency versions have aged, so newer Spring releases mean fixing errors yourself, and one reviewer suggests using an AI assistant for that. Another says the instructor names each step without explaining why it is done that way. A Spanish-speaking student found the English hard to follow, and one wants slides and a code repo.

The rating is 4.5 from about 6,100 reviews, with roughly 47 percent giving five stars and only 90 reviews at one or two stars. The course was last updated in October 2025, yet 2026 reviewers still ask for newer Spring versions. It is a paid course, and at four hours it is a quick map of the territory, not a deep dive. For a Java developer who already writes Spring Boot APIs, it is a sensible first pass. Plan to read the current docs alongside it.

Best forJava developers who already know Spring Boot and want a short, focused pass through Spring Cloud.
Skip it ifYou want slides, a code repo, or deep explanations of why each piece is wired the way it is.

Pros

  • Covers Eureka, OpenFeign, LoadBalancer, API Gateway, Resilience4j, Zipkin and Config Server in four hours
  • Reviewers call the explanations clear and to the point, with no padding
  • Starts with monolith versus microservices before building a student and address service pair
  • Most time goes to the topics that matter: Resilience4j (46 minutes) and API Gateway (34 minutes)

Cons

  • Some annotations and dependency versions are out of date, so expect to fix errors on newer Spring
  • Reviewers say it names steps without explaining why they are done that way
  • One reviewer wants slides and a git repo, and there are no coding exercises
Its not for very beginners, but it is short and on point. so i would give it 5 star.
ArunKumar c, a student

Labeled beginner, but reviewers say it is not for true beginners. Java and Spring Boot knowledge is required.

Course Description

***** Some Reviews From Students *****

  • Really its worth for me, he is explained very well and given examples for understanding.

  • It's a great course for Microservices with Spring Cloud.

  • yes it is good matching for me.

  • Very amazing course, whatever topics are covered by the instructor that is very easy to understand. Finally this course deserve 5 ratings.


This course is all about Microservices with Spring Boot and Spring Cloud.

If you are working with Spring Boot and building REST APIs then this course is for you. Having microservices is the new trend.

In this course before jumping to microservices first you will understand what is monolithic application ?

We will create microservices out of monolithic application so that you have better idea how to break your application and create microservices out of it.

After that you will learn to use WebClient to make REST calls between your microservices. You might have used Rest Template but that is now deprecated and Spring 5 onwards it is not recommended to use.


There is another better open to make REST calls from Spring Boot Apps and that is Spring Cloud OpenFeign REST Client. It provides decalrative way to make REST calls from Spring Boot Apps.

Service Discovery & Registry is very important while working with microservices. This course covers Spring Cloud Eureka to register microservices so that we do not need to worry about URLs of different microservices.

Load Balancing is key when you have huge traffic and multiple instances for microservices. In this course we will achieve Client Side Load Balancing with Spring Cloud LoadBalancer.

Earlier Spring was providing Spring Cloud Netflix Ribbon to achieve client side load balancing but now its been deprecated and Spring Cloud Load Balancer is being used.


While working with microservices how to handle cross cutting concerns like Authentication, logging request and response ?

This can be achieved by Spring Cloud API Gateway. API Gateway is entry point for all microservices that you have. You will learn to have Pre and Post filters in API Gateway.

Earlier Spring was providing Zuul API Gateway but now its been deprecated and Spring Cloud API Gateway is being used.


What if one of your microservices is down ?

Here comes the importance of Fault Tolerance. This course covers practical implementation of Fault Tolerance & Circuit Breaker using Resilience4j. It also covers real world example of Circuit Breaker. Resilience4j internally uses Spring AOP ( Aspect Oriented Programming )

Earlier Spring was providing Spring Cloud Hystrix but now its been deprecated and Resilience4j is being used.


How to trace down a particular request ?

When your microservices are calling each other it becomes hard to identity where is the issue. But do not worry here comes Sleuth and Zipkin for that purpose. We can have Distributed Tracing with Sleuth and Zipkin. Zipkin Server provides UI to trace down the request.


Centralizing property files and having environment specific property file is needed for each microservice. This can be achieved using Spring Cloud Config Server. This course covers practical implementation of Spring Cloud Config Server using Git.


Below are the topics that this course covers -

  • Monolithic Vs Microservice

  • WebClient To Make REST Calls

  • Spring Cloud OpenFeign REST Client

  • Spring Cloud Eureka - Service Discovery & Registry

  • Client Side Load Balancing with Spring Cloud LoadBalancer

  • Spring Cloud API Gateway with Pre and Post Filters

  • Fault Tolerance & Circuit Breaker with Resilience4j

  • Distributed Tracing with Sleuth and Zipkin

  • Spring Cloud Config Server


For this course you can use any database and any method to connect your database from your Spring Boot App. For example I will use MySQL database using Spring Data JPA in this course.

Its not for very beginners, but it is short and on point. so i would give it 5 star. Some places you might find some dependency version issue, but you can over come that with chatgpt/claude

By Ulises García on 8/5/2026

Bien , sólo que me cuesta trabajo entender el inglés del instructor. pero hasta ahorita bien la introducción , concreta, sencilla y práctica

By Tejas Nambiar on 7/6/2026

Yes. its a good revision. but for 2026 spring updates, would appreciate an update in course material at certain places as few annotations have been deprecated and need slightly different wiring.

By Veerendra potula on 6/27/2026

Course is really good and complete in 4 hours. If we provide slides or some documentation and git repo for the code it is really helpful to practice.

By Robert L. Sweeney on 6/10/2026

Shows the transition of the product throughout various phases. One thing that I have noticed utilizing copilot is that its examples extend beyond versions used by an application.

By Madu Biradar on 6/3/2026

This is excellent course for spring cloud so far I have visited. Explaination is clear and concise to the point. I would to see more videos from this author.

By Anonymized User on 5/30/2026

The course is very nice to learn about Microservices with Java Spring boot and Spring Cloud I learn so many things which i don't know early. But I want to add your explanation aur notes of topic in resource and add more ppt and flow of services example while explaining.

By Mario Zamora on 5/13/2026

Good Explanation and i like the short time the videos last, because when are large videos i get bore

By Pankaj Goswami on 4/30/2026

Just an crisp and clear course to get started with api gateway design pattern along with other very useful and critical topics covered that are very important in interviews and work as well. Its a great course to have a quick start on the microservices architecture. After taking this course it will be very easy for anyone to understand the advance concepts through documentation because now you understand the big picture. happy learning.

By Rishabh Jaiswal on 3/22/2026

Yes for doesn't knowing anything from microservices to having enlighten on the same Love this course help's allot.
