Quarkus, the new “supersonic, subatomic” Java framework is currently getting a lot of attention.
The ideas behind this build and runtime tool are indeed more than interesting for the future of enterprise Java.
What are the benefits and shortcomings of using Quarkus?

I’ve recorded a video how to minimize the development turnaround times with Watch and Deploy (WAD) by Adam Bien and Docker containers.
The WAD tool watches for file changes and will re-build and re-deploy our applications to an auto-deployment directory.
We’ll see how that approach can be integrated into containers that are created by the same Docker images that run in production.

I’ve recorded a video how to implement the bulkheads and backpressure using MicroProfile Fault Tolerance.
The idea behind bulkheads is to split applications into several execution units that isolate functionality.
In enterprise Java applications this typically means to define multiple thread pools.

You can make the Prometheus configuration aware of the Kubernetes environment your applications are running in.
I’ve described how to do that manually, in a previous blog post.
Prometheus Operator is an extension to Kubernetes that manages Prometheus monitoring instances in a more automated and effective way.

It seems that more and more enterprise technology is emerging that is based on Java EE.
There are a lot of options to choose from, between Java EE (now referred to as Jakarta EE), MicroProfile, and combinations of their APIs.
If we look at available application containers, the number of possibilities is even higher.
Which platforms, particular standards, and runtimes should enterprise developers base their applications on in year 2019?

Prometheus supports scraping multiple application instances.
Applications that run in orchestrated environments require to be discovered dynamically, since their IP addresses will change.
Prometheus can be configured to use the Kubernetes API to discover changes in the list of running instances dynamically.

MicroProfile 2.2 just has been released with updates to the Fault Tolerance, Open Tracing, Open API, and Rest Client APIs.
What’s also supported since version 2.2 is the usage of BOM (bill of material) dependency imports.
