Keynote | Java - unlimited in the cloud
Let’s remove the illusion of limits. Step back and rethink. Especially on boundaries that might just be in our head. Microsoft is one of the leaders in distributed Java and even has its own build of OpenJDK. Microsoft’s open-source contributions don't only focus on Java and the OpenJDK, but also Linux, VS Code, TypeScript, Kubernetes, and many more. Many of our tools and approaches are available outside of Microsoft as well. It's an exciting time to use technology to build and deliver whatever you can imagine. We are building value together and welcome everyone to participate and go beyond limits.

Keynote | DDD, CQRS, and Event Sourcing, beyond the hype
The demands of software changed dramatically in the last 20 years. Yet, the dominant architectural styles are still based on patterns from the 70s. Although new architectural patterns have emerged, the benefits are often brushed aside. How can we take advantage of these benefits? How do we keep up with the changing non-functional requirements? In this session, we’ll weed out the hype around Event Sourcing. We will look at how DDD, CQRS, and Event Sourcing are combined to form an architectural style that allows us to separate the behavior from the technical details.

Keynote | What Would a Startup Do?
Imagine we quit our jobs and create a startup to create the next killer app. What would we do? Would we start on bare metal, use VMs or containers, stay on-premise, or go to the clouds, or even rent servers on colocation? Would we implement microservices, monoliths, event processors, functions, and should we still use Java?
In this freestyle keynote conversation, I would like to highlight different options and their impact on productivity, maintainability, and event costs.

Keynote | In Memory Data Processing with Java
The 4th industrial revolution has begun. An incredible transformation has been running. Communicating edge devices, self-driving cars, drones, robots, combined with AI and ML algorithms, will change our lives more than anything else before in mankind. Data is the gold of this age. However, everything depends on the ability to process these data highly efficiently. High-performance systems will win. Legacy systems will lose. Java provides you incredible performance, just use it.

Keynote | Quarkus Deep-Dive
This keynote talk dives deep into the internals of Quarkus and explains how its unique architecture makes it different from other frameworks. We will start with an overview of the architecture, then cover how extensions work, and finally go in-depth on the internals of developer productivity features such as continuous testing and Dev Services. By the end of the talk, we will have covered how Quarkus gives you the best of both worlds, with a first-class development experience that still results in small optimized applications.

About JCON-ONLINE 2021
JCON-ONLINE 2021 is the big international Java community conference organized by the Java User Group Oberpfalz in cooperation with JAVAPRO Magazine. Java is our profession and JCON our passion and a lot of fun. We love to provide Java developers a spectacular 100% live conference that is open to the entire Java- User-Group communities world-wide.
Last year, more than 2,000 participants from 51 countries worldwide have joined the JCON- ONLINE 2020.
The 5th JCON edition is presented as an online live conference for the second time. All sessions will be streamed live and recorded.
Focus on Core Java & Cloud-Native Java
JCON traditionally focuses on Core Java, Serverside Java, APIs and Frameworks because that's what we as Java developers work with every day. However, the main topic will be Java-Cloud-Native and Microservices, because this is the future of Java and must-have for Java developers.
