Java applications can be a pain to operate on Kubernetes as many of them have been developed without containers and Kubernetes in mind. Operations folks are forced to understand how each of them gets configured (was that a system property or env var?) how it was crammed into a Docker image (Spring Boot self contained […]

J-Fall Virtual 2020: Alex Soto – Serverless-Native Java with Quarkus

Serverless architecture is exactly the opposite of a monolith architecture, small services (or functions) running in a constrained running environment (limited access to CPU and memory). Furthermore, as we move to a model where we pay per usage, the services might need to go from 0 to infinite instances in a matter of milliseconds to […]

J-Fall Virtual 2020: Duncan Bloem – Migration strategy from (10-15yr) old Java-EE app to modern cloud native apps

10 to 15yrs ago, ABN begun leveraging internet banking. Many (thousands) of web-app were written in java-ee style, deploy on IBM Websphere clustered machines.

Nowadays, we […]

J-Fall Virtual 2020 – Gunnar Morling & Andres Almiray – Plug-in Architectures With Layrry and the Java Module System

The Java Module System lays the foundation for building modularized applications on the JVM. It doesn’t concern itself though with resolving module versions and obtaining modules from repositories. This is where Layrry comes in: an API and launcher for modularized Java applications which takes a descriptor of the module layer(s) to assemble, fetches the modules […]

J-Fall Virtual 2020: Holly Cummins – Cloud chaos and microservices mayhem

The way we use Java has changed. Applets – or any browser-side Java – are a long, long, time ago. Java moved to the back end, and stayed there, but the back-end has gotten bigger, more distributed, and more complicated. Some things that were a good idea ten years ago turn out to be a […]

That by itself poses […]
