Last year’s OSDC already was a huge success and I really enjoyed all the technical presentations as well as – of course – the tasty food & evening event. So why bother joining my colleagues and the conference this year again? Reading through the speakers list unveiled a certainly interesting program fully packed into 2 days with one day full of Vagrant/Docker/Logstash workshops in advance. For what it’s worth, day 1 was already mind-blowing to me.
After Bernds funny-as-we-love-it welcome presentation Nigel Kersten took over in room MOA5 with “In defense of datacenters”. What we learned is definitely that Europe and the US think different with “putting something into the cloud”. While there are still people around being “cloud skeptic”, the presentation also unveiled some changes going on – from “automate all the things” towards “how to integrate your app containers” into.

 
Not only Nigel was taking that into account, Mitchel Hashimoto (I tend to call him “Mr. Vagrant”, life-saver in many Icinga ways) also referred to that later on in his presentation on “Automating the Modern Datacenter: Development to Production”. He also explained how tools at HashiCorp work, and added examples on how to combine open source tools such as Vagrant, Packer, Consul, and Terraform.
Kelsey Hightower did go fast in his presentation towards an awesome live demo on distributed systems with CoreOS, Kubernetes & Fleet. Actually this demo looked pretty easy, I bet everyone can just do that on their notebooks while driving back home from OSDC. And it also made it clear – the cli is becoming important again with all the tools involved. User interfaces are nice, but the real processing happens on the command line, combined with clusters, automation, monitoring, etc.

Entertaining and smiling the noise irritations away, James Fryman gave an awesome insight on why you would want to use #chatops. Some ops stories from GitHub while sharing real world scenarios from his current employer StackStorm, plus the advice to make your bot a human character (“Bob”) let time just go by and we certainly will have to look into Hubot and how they are called 😉 Pricessless answer to “How much does #chatops disturb admins in $dayjob?” – “It saved them a lot of time, let them slack off a bit.”

Jan-Piet Mens started early with G&T time reducing the nervosity level – according to the audience his talk on MQTT for the datacenter was pretty much a blast. And hey, he didn’t mention the “N”-word, but just #icinga 😉

I did know about Apache Mesos a bit as we were evaluating it for package build clusters at NETWAYS a while back. The presentation on “Why the Datacenter Needs an Operating System” by Bernd Mathiske included an introduction into the entire framework with programmable interfaces and orchestration. It’s pretty clear – there is so much going on the near future in the open source world, and so little time to put everything together 😉
Bernd Ahlers gave an introduction into configuration management systems, including Icinga 2 which is – obviously – a personal interest. Other than that it’s also primarly Graylog for log management and putting it all together. As we certainly learnt from many places – APIs all over with enterprise intergration.
Time-series databases have been referenced in many of the talks before so it was really a pleasure listening to David Norton on InfluxDB finishing the first day of OSDC. 1.2 million series & 400k points/seconds sounds pretty impressive for the upcoming 0.9.0 release. And it can be directly hooked into third-party user interfaces such as Grafana which beats sort of Graphite Web vhost and other problems.

Right now we are preparing for the evening event at the Paulaner-“we can’t spell the rest, not important anyways” in Berlin – be sure to follow the #osdc twitter feed for some updates & pictures. If you can’t be here – save the date already for next year – 26.-28.4.2016 – and join us then 🙂 Or, as Nigel Kersten said – convince your boss 😉

Cheers!
