Keynote | Thinking About Persistence for Serverless Java

Serverless Java applications are stateless and store their data in a range of cloud persistence stores, from relational databases, like Aurora, over file-based block storage like S3 to persistent event stores like Kinesis.
In this keynote, I will focus on the characteristics and challenges of serverless Lambda and Fargate Java application's data access layer and discuss the impact on authentication, authorization, connection handling or scalability, data mapping, portability, and costs.
Your questions are highly welcome!

Keynote | Kubernetes Native Java

Spring is all about helping developers get to production quickly and safely. These days, "production" is all but guaranteed to mean Kubernetes, and Spring has you covered. Join me, Spring Developer Advocate Josh Long (@starbuxman), and we'll look at how Spring Boot makes writing blisteringly fast, cloud-native, and scalable services more effortless than ever.

Keynote | Warp 36 Java In Memory Data Processing Cluster

With just-in-time compilation, the JVM creates Java byte code to highly optimized machine code. Operations on data in memory are executed in microseconds with Java. Only 1 Java machine can achieve performance comparable to an entire traditional database cluster. This approach enables the development of high-performance applications with pure Java that provide low-latency real-time responsiveness, handle gigantic loads, and radically save infrastructure costs.

Keynote | Developer Productivity Engineering – The Next Big Thing in Software Development

It's 2022, and as IDC predicted in October of 2020, 65% of the global GDP has been digitally transformed. Two-thirds of the products and services that you pay for are driven by software, and the quality, cost and time to market of your software products determine the fate of your business. There has never been a more important time to foster developer productivity, but many of our methods have not evolved. In this keynote style talk you will learn why DPE is the most important development in the software engineering world since the introduction of Agile and DevOps concepts and tools. DPE is a new software development practice that uses acceleration technologies to speed up the software build and test process and data analytics to improve developer efficiencies by as much as 10x. The ultimate aim is to achieve faster feedback cycles, more reliable and actionable data, and a highly satisfying developer experience. Justin Reock, Field CTO and Chief Evangelist at Gradle is pioneering DPE as a practice and set of technologies and is one of the world’s leading advocates. Specifically, Justin will provide an overview of the key concepts and tools, business impact on key business objectives like time-to-market, cost and quality, the business case for DPE, and the role of AI/ML in DPE moving forward.

The Original JCON CONFERENCE

UCI Cinema Duesseldorf, Germany, 2019

Motivation

We love Java. That's why we want to bring together Java developers from all over the world. To learn, to connect, to have fun. The feedback we receive proves us right and motivates us to keep going.

Team

JCON is a team effort and a conference by developers for developers. The JUG Oberpfalz does the heavy lifting in organizing everything. But the heart of the conference are our speakers with their sessions.

Community

We often work in completely different branches, but Java is our common denominator and connects us all. Over the years, not only acquaintances but friendships have formed on account of JCON!
