Typo above.  Should be 'Spring In Action' book.

By the way, I believe there is also an available book or preparation course on Spring 5 certification now.  Try Udemy or amazon.

I want to go for spring core certification but I couldn't find any good reference. I have searched and googled about it and what I came to know is about the book spring in action 4th ed. But I also went on and came to know that many people have used this book for this certification but didn't do well on the exam.

So if anyone knows some good reference for spring core certification that I should use for the exam please tell me.

There is now a 5th edition of Spring 5 In Action, for Spring 5.

Please note that the list of topics in the exam is in Pivotal website.  More than half of the book is not part of the exam.  For deeper, more complete knowledge to prepare for the exam, you can refer to the Spring Reference, on the related topics.

My practice tests are based on the Pivotal list of topics.
They are at (Spring 5, 4.3, 4.2), and (Spring 4.3, 4.2).

Thank you for the reply.

In terms of technology, I heard of Spring Cloud (java-based development) + Travis CI/CD + Docker + AWS, as a good combination.  What do you think?

And also what are the other tech stack options when designing a cloud native system?

so I found that quite disappointing as I like to study in mobility my Spring 5 exam

Hi Mike,

If you have internet connection on the move, you can use itestjava on your mobile browser.  It is responsive and the page will adjust based on the size of your device' screen.
The Pivotal guides for the Core exams  (4.2 to 5) are currently at:

I noticed that React* is not in the Spring guides above, for 5.0.  There are A LOT of topics not in the exam.  I suggest that you refer to the guides so as not to waste your time studying the wrong topics or topics not in the exam.

There are practice tests here below for 4.2 and 4.3:

I am still currently completing the one for 5.0.

Pete Letkeman wrote:What about Cloud Foundry knowledge and/or certification?
Cloud Foundry was created by the company behind Spring/Spring Boot.
You can audit a course on this topic for free at, but if you want a badge for your Linked In/CV then you need to spend money.
Cloud Foundry also has a certification path which cost money.

In addition to or perhaps in contrast to Cloud Foundry, you may want to know about AWS.

I'm unsure if you have mentioned anything regarding databases. You may want to know at least the basics of either SQL and/or NoSQL systems.

Yes, I have personally benefitted on certifications.  Thank you for the tip.  I will keep Cloud Foundry in mind, as it might also have better easier integration with its brother the spring framework.

AWS knowledge is probably essential, as many companies use it.

For DB, for Spring Cloud Config, we can use Redis, etc.  

I still have to look at NoSQL systems.  Regardless, Spring Data definitely will be there to help, as usual.

Agreed.  Most of the other technologies I mentioned is to implement the good case scenario of easiest effort from all involved:  architecture, developer, devops.

Devops is assisted most by using images like Docker, and continuous integration/deployment tools like Travis and Jenkins.

I just read Spring Microservices in Action, by John Carnell.

Docker, Hystrix, Ribbon, Eureka, Spring Cloud (Config, Stream, etc. etc.), Maven, Spotify, Zuul, are some of the technologies that come to mind quickly that were mentioned and used.

To those who are actually working or have worked in microservices, what technology did you use?
