Follow up: which interview questions would I ask you in an interview.

  • Do you use OpenJ9 JVM in some production system?
  • Is not clear to me when and why I should use this JDK, people don't even talk about that...🤷‍♂️ 🤔

I watched your video from 2 years ago and you compared the memory consumption of OpenJDK vs OpenJ9. It seems that OpenJ9 consumes very less RSS memory compared with other vendors.

In the past people tend to use Remote EJBs or RMI for server-to-server communication.
Now we'll have the Jakarta gRPC spec but we already have a Quarkus guide and a WildFly feature pack that adds support for gRPC.

  • Does running a bare metal WildFly HA cluster with master-slave approach makes sense?
  • And what about automate standalone .war deployments with Ansible instead of relying on the master domain node?

⚠️ For newer projects I prefer to think about cloud (12 factors & containers) over other traditional architecture, today things are getting easier as we've managed solutions like Openshift, but at the other hand we also have legacy projects made before the cloud era and sometimes these projects are not easily portable to the cloud :/ that's why I'm asking here.

By the way, it seems to me that few developers understand how Jakarta EE and application servers works, some of them are deploying Spring on application servers so it’s like buying a Ferrari - JBoss is the Ferrari - and installing a second engine on it (Spring) plus a second set of wheels. IMO we shouldn't compete with the platform but use it at our favor.

Thanks!! 😁

Are shared deployments back?

Have you ever got a good enough reason to switch to hibernate reactive and mutiny in any of your projects?
