AGENDA
🧑‍💻 18:00 - Hardcore Serverless Java - Adam Bien
🍕 18:45 - Networking and treats
🧑‍💻 19:30 - Optimization of serverless workflows on AWS Lambda - Arkadiusz Zdanowski
🙋‍♂️ 20:15 - Wrap-up and closing

SESSIONS
👉 Hardcore Serverless Java
This session cuts through the complexity, showing how to build robust, maintainable systems that leverage managed services as first-class citizens in your architecture. I'll demonstrate practical techniques for crafting ultra-lightweight, NoOps applications that dramatically reduce boilerplate while maintaining enterprise-grade security and isolation. Serverless Java 21+ isn't just pragmatic—it's revolutionary for enterprise applications.

Prepare to see real Java code that starts serverless, leverages managed services, and delivers production-ready systems with minimal ceremony. Not for the faint of heart 😀—expect coding and practical techniques you can apply immediately.

👉 Does size matter? Optimization of serverless computing on AWS Lambda.
In this session we will end wars, do the impossible, and unveil the hidden. We’ll end the battle between Intel and AMD by putting AWS Graviton ARM processors to the test against x86. We’ll attempt the impossible—saving both cost and performance in AWS Lambda. Finally, we’ll explore a tactic you won’t find in the documentation - the art of right-sizing Lambda functions.
