A general talk about Open Source as a Business, what this means and especially what this does not. Held at an Elastic Event in Munich.
Elasticsearch is running on tens of thousands of nodes world-wide, so despite all the functionality squeezed into new releases, we also have to think about security, all the time. This talk will cover different aspects of Elasticsearch, explain some features and (sometimes unpopular) decisions and the reasoning behind. The goal of this talk is not (only) to show off Elasticsearch features. You start thinking about these non-functional requirements in your own applications as well! Held at the Java User Group Munich, at the Mathema Campus, the Search Meetup Munich, the CFCamp and the Java User Group Erlangen/Nürnberg.
Maintaining a well known open source stack is no easy task. Despite fixing bugs and adding features, releases need to be aligned among products and each product needs to be tested on its own. This talk starts at the lowest level of Elasticsearch, explaining how we run unit tests, moves up to integration tests, packaging tests, backwards compatibility tests, performance tests, including commercial extensions in testing phases - all of this on different operating systems and JVM versions. Attendees will get to know how our CI looks and how all of our products (Elasticsearch, Logstash, Kibana, Beats and all of its commercial extensions) are released at the same moment in order to ease the upgrade process for our end users. Held at the Ryte Tech Meetup, also available on video and the TestCon Moscow 2018.
A quick overview about the commercial plugins for the Elastic Stack, where I covered the alerting backend part during ElasticON 2017. Also available on video.

The corresponding blog post is is on the elastic blog. Held at the Search Meetup Munich, the Search Meetup NRW and the Search User Group Berlin (plus video).
A small introduction in the serverless paradigm and introduces the serverless and claudia frameworks for node.js, provides some more information about other language alternatives and of course also about the drawbacks to be aware of. Held at the Munich Node User Group, also available as video.
The Elastic stack consisting of Elasticsearch, Logstash, Kibana and Beats offers easy-to-use components to ingest, parse, analyze and visualize your data. In this talk we will focus on the aspect of log files, and in addition to the already known capabilities of the ELK stack new features in Elasticsearch simplifying your logging life and the relatively new Beats and their respective implementations will be covered as well. Held as a keynote at the Cloudconf in Italy (video), at Infoshare at Gdansk, at CFCamp in Munich and at JUGH in Kassel (video).

A very highlevel talk about why you need something like the ELK stack to make better business decisions, and why we (as a company) think, that this different pieces of software are needed. Held at the mimacom days in Zurich in June available as video.
A talk not so much about elasticsearch (even though it features a quick intro), but about the full stack ranging from hardware, operating system, jvm, garbage collection, libraries and some elasticsearch examples to make you aware of the complexities of having performance in such a complex distributed system and how to optimize a few of them. Held at the NoSQL User Group in Munich and at TNG Consulting in Munich (thanks for inviting me!).
A brief overview about recent elasticsearch features, continously updated from 1.0 onwards over the year.
