So, how hard is it for a seasoned Spring developer (5+ years experience) to crack this exam?
Are there any practice resources to feel comfortable or test your readiness for the exam?

Java Bloat has been my biggest pet peeve for a long time now and why I started programming in Golang for some of my personal projects. But Jigsaw is a welcome change and a step in the right direction for Java. I think there is a maturity model for the use of the Java Module System... As I typed that, I googled to see if there was someone who had outbeaten me to the idea... and surprise JPMS Maturity Model Thanks Nikolai

So with jlink, will this change how we have traditionally shipped java applications? Thoughts? Much like how we use docker, to deliver products.

Thanks for the link. Very detailed and very well organized.

Doesn't Kubernetes support this as well?

With Docker announcing native support for Kubernetes, what do you think their direction with Swarm will be?

Sure, you can do that easy with angular directives. Also have you looked at ng-bootstrap?
Nice, this discussion gives me more tools in my arsenal when I go to the design meetings for our next UI project.
Thanks for all the resources.

So in summary, there is a lot of mixed opinions based on where that information is coming from.

Why should one go for Kubernetes over Docker Swarm for deploying/clustering containers or could it be a mix of both from a redundancy perspective?

Great answer... Really appreciate the details on it.

Also, Does embracing Docker as an Application Delivery System bring any value to the Open Stack?

Would I still need Openstack if I were developing on Docker with an orchestration framework like Kubernetes, Swarm, etc?

Need more than to help you out here. Do you have the source code to share? How are you running the app. From what it seems is you have 2 pieces to the app. The rest backend and the ionic frontend. Are you starting them off separately?

Grails uses Spring under the hood. And you can use servlets within a grails app.

If you are looking for a framework that can scaffold easy and you can get it up and running in no time, go for Grails.
