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!
- The IGT Cloud Meetup Group is hosting a workshop on Applied Cloud Computing with Google Cloud Platform at Google Tel Aviv. Topics will include BigQuery with Logstash as Application Log Analysis Platform. The workshop runs from 9:30-13:30 on July 7th.
- The Second Elasticsearch Tel Aviv Meetup will convene on July 28th, focusing on real world use cases. The agenda is still being finalized, but registration is already open.
We've got not one but two awesome conferences going on in Amsterdam later this week:
- DevOps Days Amsterdam: Join us June 19-21st for an Elasticsearch workshop, a little on DevOps for Happier Humans and all the news you can use at the Elasticsearch table. Swing by to say hello to Leslie Hawthorn and Kurt Hurtado! Lee Hinman will also join us for the workshop. Yay Lee!
- GOTO Amsterdam: Our CTO, Shay Banon, will treat the crowd to a deep dive on Elasticsearch's APIs, plus we'll have lots of knowledge and swag on offer at our booth. See you there!
Plus, we're hosting Friday drinks on June 27th at 6:00 PM in Amsterdam. You'll have the chance to meet tons of our core developers, as the whole company will be visiting our EU HQ that week for our annual all hands gathering.
- New Meetup: The San Francisco Ruby on Rails meetup group will get together tomorrow night, Thursday June 19th, to discuss Elasticsearch and Logging. Doors open at 6:30 PM and registration is still open.
- New Meetup: The Boston Puppet User Group will get together on June 24th to discuss how you can build a modern infrastructure in just 45 minutes. They'll be talking Logstash as part of the festivities. Doors open at 7:00 PM and registration is still open.
- The Philadelphia Elasticsearch Meetup group will be getting together for their second meetup on June 26th. Details are still in the works, but sign up now so you know where to go for ELK treats on the 26th.
- The SYN/(st)ACK NYC User Group will convene on June 30th at 6:30 PM. Squarespace is hosting the festivities, and Franklin Angulo, one of their Software Engineers, will be presenting. Franklin will cover building a scalable monitoring and alerting system using Graphite, Grafana, Collectd, Nagios, Logstash, Elasticsearch, and Kibana, among others.
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 Elasticearch, Kibana, and Logstash than where you rest your head.
