21 Minutes About Java 21 Performance
From Virtual Threads to G1GC Humongous object, and Generational ZGC and Vector API. Java 21's JVM is packed with performance improvements. Let's quickly go over them.About Haim Yadid
I am a software engineer with 30 years of experience in various technology fields: software development, engineering management, software architecture, HPC and algorithmic research. In my day job I am an Engineering Fellow in Next Insurance. Before that has been focusing for 8 years on Java platform performance optimization as an independent consultant and was involved in more than a dozen optimization projects. My passion for performance optimization hasn't faded, and I still love to tackle challenging problems of this kind. In addition to my work, I am a Java Champion and one of the organizers of Java.IL, the Israeli Java user group.Embrace Domain Driven Design with Spring Modulith
Spring Modulith is a new way to organize Spring projects according to business domain instead of by controller/model etc. In addition it leverages Archunit to preserve the architecture in the project. My talk will introduce listeners to these topics.

Snapstart: 10x Cold Start Boost for AWS Lambda!
I love working with Java-based lambdas, but one of the primary headaches is the infamous cold start, it costs us time and money.
Fortunately, AWS came up with a solution, the SnapStart!
In this lecture, I will explain exactly what SnapStart is, how it reduces the cold start duration, and how to implement it properly, step by step.
I will present actionable and easy-to-implement SnapStart best practices and show you how it makes everything faster.
