Cloud-native Java with Quarkus, Mandrel and Jib

Nowadays, Java is considered to be mature and classical. Though the Java technology might not be a modern one, it’s still at the forefront of the trends and en vogue. It still has a strong influence and is widely spread in a number of system landscapes, which are evolving at this very moment to follow cloud transformation trends. The challenge lies in hauling Java up into the cloud as lean and nifty as possible.

I’d like to offer a solution to the above-mentioned challenge. That is when the CDI framework Quarkus comes on the scene. It’s lightweight at first glance, and yet it has an enormous potential due to an exquisite collection of the best of breed libraries and standards. Additional components of this solution include Mandrel, which provides native Java builds, and Jib, which simplifies the build process. This results in a container image of your Java App being built and pushed to your container registry in one step.
