About this event

On short-term notice, we'll have interesting visitors at QAware next week, and we want to invite you all to join us for two talks.

We'll open the doors at 17:00. Talks will start at 17:30.

Moving to GC1
SPEAKER: Kirk Pepperdine

Come Java 9, our beloved mostly CMS collector will be depreciated and the G1GC will replace the Parallel collector as the default. The hype surrounding this massive change that the G1GC is the best collector… ever. Make no mistake about it, G1GC will be much much easier to tune. So, is this real or is it #fakenews.

In this session, we will explore the reality by looking experiences moving applications from CMS to G1GC in real production environments. The implications aren’t simply about performance. A sub-optimally tuned collector will increase your companies operating cost by 10-20%.

We will also explore results from benchmarks that expose potential pain points. and offer some suggestions on what actions can offer some relief.

Cloud Native 12-factor JEE Apps
SPEAKER: Sebastian Daschner (Freelancer)

Warum sollten sich Entwickler um Buzzwords wie Cloud Native, 12-factors, Resilienz, Reactiveness und Skalierbarkeit kümmern? Warum ist es im Jahr 2017 eine gute Idee, diese Konzepte in unsere Applikationen zu integrieren? Und welche Technologie brauchen wir dazu?

Dieser Vortrag zeigt, was nötig ist, um cloud native, adaptive und skalierbare Applikationen mit Java EE zu entwickeln, welche Erweiterungen und Libraries dieses Frameworks existieren und warum gerade Java EE perfekt in die Container-Welt passt. Wir werden sehen, wie die 12-factors Prinzipien moderner Applikationen mit Java Enterprise vereinbar sind. Die meiste Zeit wird mit Live-Coding verbracht.

Get-Together, Networking etc
Of course, nobody should go hungry or thirsty.
