My talk will be on October 4, 2023, at 10:15.


Many Java apps are migrating to the cloud. Yet, on the cloud, Java is frequently more expensive than alternatives such as Go. Native Java using the static GraalVM Native Image AOT (Ahead-of-Time) compiler reduces the cost of Java. Native Java became popular because frameworks such as Quarkus and Micronaut, and Spring Boot 3.0 provided it a significant boost. Do I have to learn a new framework, such as Quarkus or Micronaut? How does native Java function? And when will it be worthwhile for me to learn native Java? These are the topics of my presentation.

Who Made Me the Expert?

In the spring of 2022, I was the editor of a highly popular, six-part article series about native Java on InfoQ. I have data to back up my claims. And Java experts helped me.

Unlike some other talks which are either pro or against GraalVM Native Image, Iā€™m neutral on it. I’m the Switzerland of GraalVM talks! Which is quite fitting, as my current project is in Switzerland! šŸ˜ƒ I’m not selling books or training courses, and I’m not a developer advocate. I share my experiences and my knowledge so you can do get better projects faster!

Java Tech Popularity Index Q2/2023:
The number of developer ads is down in 2023 by about 25%. Spring Boot is back to 500% of Jakarta EE job ads, while Quarkus and Micronaut rose again after a four-month decline. The monthly number of Stack Overflow questions is down 42% since ChatGPT appeared.
