🇬🇧 3 years of Quarkus in production, what have we learned? by Jago de Vreede (TenneT)
Quarkus has grown in popularity in the last years, but what’s it really like to use it in large-scale, real-world business projects? In this session, we’ll move beyond the basics of "Hello World" to explore how to build enterprise-level applications with Quarkus efficiently.

In this talk we will set up a multi-module project, incorporating integration tests and addressing the challenges with build times, while maintaining a high development velocity. Next, we’ll tackle an upgrade scenario and splitting the application into multiple microservices. Along the way, we’ll share hard-earned lessons, including what to avoid.

At the end of the talk, you should have a good understanding of how to efficiently set up a “big” enterprise project with Quarkus and the confidence to get started.

🇬🇧 The Balance act of logging by Robert Scholte (Sourcegrounds)
Let me ask you: Is logging useful? This question is hard to answer upfront. Often the main purpose of logging is analysis when having an issue. If there are no issues, there’s probably too much logging. However, when there is an issue, you need to have enough information to make well thought decisions. To be able to do that, you need to decide upfront what to log. At the same time, logging claims resources as in IO, which can have a huge impact on the performance. And with the cloud engineering, resources means costs.

This session will demonstrate that the impact already starts with the buildtool, but also how to control it. Based on this knowledge you can not only improve your own builds, but also your applications.
