Elasticsearch Ecosystem

Here's some more information about what is happening in the ecosystem we are maintaining around the ELK stack - that's Elasticsearch plus Logstash and Kibana - including plugin and driver releases.

Slides & Videos

For those of you who want to get your hands dirty with the ES-PHP client, here's a nice intro tutorial for you to sing along with.


Were you at OSCON a few weeks back? The Elasticsearch team was and there were some great talks from our merry band of humans - including this one from our intrepid community manager Leslie Hawthorn.


And lest we forget, there were also a few great OSCON presentations from our amazing Elasticsearch community members, including this presentation from our friends at Mozilla.

Where to find Us

We'd love to feature all the great Elasticsearch, Logstash, and Kibana presentations and meetups happening worldwide in this section. If you're speaking or hosting a meetup, let our Community Manager, Leslie Hawthorn, know!

Germany

If you're heading to FrOSCON on August 23rd & 24th, we're happy to bring you bouncy castle love this year. And make sure to see Isabel Drost-Fromm on Your Search Doesn't Work.

Poland

The Warsaw Java Users Group is holding a Microservices Hackathon on August 9th from 10 AM to 10 PM. You can spend those twelve hours hacking on the ELK stack and a variety of other tools. Register now to attend.

United States

Heading to Chicago for LinuxCon and Cloud Open North America? Say hello to Leslie Hawthorn, and check out her panel Empowering Your Corporate Open Source Software Developers.

Where to Find You

Our Community Manager, Leslie Hawthorn, is hard at work to help folks create more Elasticsearch meetup groups and to help meetup organizers find more speakers. If you are interested in either effort, take a moment to let her know.

Oh yeah, we're also hiring. If you'd like us to find you for employment purposes, just drop us a note.  We care more about your skill set and passion for Elasticsearch, Kibana, and Logstash than where you rest your head.
