Give your application memories

Milen Dyankov (AxonIQ)

Most applications only know the present. Their current state is calculated and updated somewhere on every change, effectively losing any previous states and information that only existed in the past. Can that be a limitation? Missed opportunity? What if your application could remember its entire history? Would that be any helpful, or is it a worthless effort? This talk will provoke Java developers to start asking such questions. It will provide useful mental models to better understand Event Sourcing, DDD, and CQRS concepts.

Deployment options for OSGi applications in the cloud/edge

Dirk Fauth (Robert Bosch GmbH)

There are different ways to deploy a Java application. Traditionally it was a single JAR or a collection of JARs on a machine that has a matching Java Runtime installed. Today there are additional formats like a custom created JVM via jlink or a native compiled Graal Substrate. This gets especially interesting when thinking about deployment of smaller applications for processing tasks via containers in the cloud or on edge devices.

OSGi.fx - Unleashing an OSGi console for modern era

Amit Kumar Mondal (Deutsche Telekom AG)

OSGi is around for many years and is currently the de facto standard to build modular applications. It provides a long list of open specifications making it possible to define the dependencies of each individual module with others and enable users to control the lifecycle of the components in the system. External tools are still required for the runtime configuration and management of the framework and bundles deployed within it.
