Arun Gupta on "Chaos Engineering"

Sabotaging a software knowingly in order to write it more reliable ­­– that is the approach of "Chaos Engineering". In this important component of modern software development, developers use simulations and experiments to find out what effects different conditions have on a system. In the opening keynote, Arun Gupta, Principal Technologist at Amazon Web Services (AWS), shows how Chaos Engineering works. The keynote speaker is also known in the Java community as an author of several books, enthusiastic runner, globetrotter, docker captain, Java champion and JUG leader.


Community Keynote

In previous years, the community has shown itself to be extremely creative and entertaining in its keynote. During the 45 minutes slot moderated by Christoph Engelbert and Hendrik Ebbers, the community certainly made some participants laugh to tears. What will come after the quiz of 2018 and the "Double.POSITIVE_INFINITY War" of 2019? As usual, the community is secretive in the preparation; that's why we know absolutely nothing about the next edition at this premature date. Anyway, we are very excited about their next keynote.
