Many Java developers encounter the limitations of traditional caching and database solutions when dealing with large amounts of data and dynamically growing workloads. Heavyweight systems often prevent flexible scaling or unnecessarily increase infrastructure costs.
The session “High-Performance Caching with Pure Java – Part 2: Managing Gigantic Workloads“ at JCON EUROPE 2025 presents an approach that does things differently: Instead of complex architectures, this approach relies on pure Java – lean, scalable, and powerfull.
Hands-On: Scaling and In-Memory Architectures with Pure Java
In this two-hour hands-on session, Christian Kümmel will demonstrate a field-tested approach for building dynamic, distributed in-memory layers – entirely without the need for additional, heavy-duty caching frameworks.
Instead of relying on slides or theoretical concepts, participants will actively work on their own code and test methods that have already been successfully used in large-scale production systems.
Why Participation is Worth Your Time
The workshop is designed for developers who want to build scalable Java systems or optimize existing architectures for greater efficiency, particularly in highly dynamic load scenarios and cloud environments.
Participants will learn:
- How to design high-availability, distributed caching layers using Pure Java
- How to dynamically manage gigantic workloads and microservices without external dependencies
- How to significantly reduce infrastructure costs through intelligent load balancing and scaling
- How to design modern, resilient systems for Kubernetes and cloud environments
Learn Directly from a Proven Expert
Christian Kümmel has over 15 years of experience in building and scaling complex Java systems and is currently developing a comprehensive SaaS platform for EclipseStore clustering.
His practical experience from a wide range of industries is directly applied in the session – participants benefit from proven knowledge without having to gain years of experience themselves.
Conclusion: Rethinking Caching and Scaling
This session is much more than an introduction to caching techniques: it provides a new understanding of how Java systems can be designed to be dynamic, scalable, and cost-effective today, without unnecessary infrastructure complexity.
Anyone who wants to build systems for dynamic workloads and scalable in-memory architectures will find concrete methods and best practices here.
