OSDC 2016: More for your datacenter stack

We need more coffee – the first talk of day 2 directly kicked off with automation and challenges. We are using Foreman at NETWAYS and it helps me on a daily basis to deploy development boxes with Opennebula. So it was interesting to find out about insights and challenges by Julien Pivotto with Automating a R&D lab with Foreman: What can be hard?.

Sadly the second talk about Interesting things you can do with ZFS by Allan Jude & Benedict Reuschling was at the same time – again one for the conference archive.

Decisions decisions. Mesos and the Architecture of the New Datacenter by Jörg Schad or Hybrid Cloud – A Cloud Migration Strategy by Schlomo Shapiro. I guess I’m one of those devops hipsters going for Mesos. Although I hear that its implementation can be tricky (hi Sebastian) we’re using it at NETWAYS and I wanted to learn more about it. Especially since Mesosphere recently announced DC/OS.

Ingesting Logs with Style sounds like a swiss army knife presentation style. Logs always remind me of the days when there was not Logstash or Graylog around, just some unacceptable expensive Splunk license and your own central syslog server plus some custom handmade scripts. Pere gave an awesome outlook on what’s coming with Elastic Stack 5.0 including hist sports activities as live demos.

Everyone knows about Docker. Everyone uses it in production already? Or at least tried to until the company’s security team stepped into? Inspecting Security of Docker formatted Container Images to find Peace of Mind provided insights on the most often asked questions when it comes to production deployments.
Right after lunch David Schmitt gave an interesting Introduction to Testing Puppet Modules. Being a developer and writing tests? Meh. The least exciting part right after the documentation bits. Though tests will make your life easier especially with Puppet modules ensuring they won’t break. The talk’s topic also reminds me of Tom de Vylder maintaining the Icinga puppet modules and insisting on rspec tests on every single PR – chapeau 🙂

Coming from MariaDB Colin Charles provided tipps and tricks on Tuning Linux for your Database.

An Introduction to Software Defined Networking (SDN) by Martin Loschwitz or Bareos Backup Integration with Standard Open Source Tools with Maik Aussendorf?

Finally the last talks for this years OSDC. We already learned about Puppet and Salt, now it is time for Kaiten Zushi – Chef at Goodgame Studios by Jan Ulferts. Florian Lautenschlager with Chronix – A fast and efficient time series storage based on Apache Solr was again my favourite for the conference archive.

Thank you and see you in 2017

The conference archive will be made available in the next couple of days. Save the date – 16.-18.5.2017 🙂
PS: Everything is a freaking DNS problem!

Weekly Snap: Solr, gperftools & Rootkit Hunter

weekly snap2 – 6 September entered autumn with plenty of hardware and sys admin tips, as well as a follow-up OpenNebula webinar.
Blerim began by recommending Apache Solr for indexing and showed how to combine it with Zookeeper to build a SolrCloud.
Georg then gave the lowdown on our all-inclusive Icinga/Nagios voice alert packages covering Starface VoIP appliance, software and onsite setup.
He continued on a USB wave, introducing Xsensior Lite the economical temperature and humidity USB-sensor as well as USB extensions using CAT5e cables.
In the meantime, Markus looked for rootkits, backdoors and local exploits with Rootkit Hunter and Gunnar offered his alternative profiler to Valgrind – gperftools.
Finally, Christian reminded interested participants to join our first OpenNebula webinar and consoled those who missed it with a repeat webinar on 11 September.

SOLR und MySQL-Proxy bei Tradoria

Nachdem wir ja aktuell auf die Möglichkeiten von MySQL eingehen hier gleich mal ein Praxisbeispiel für den MySQL-Proxy.
Mit unserem Kunden Tradoria GmbH haben wir den Proxy eingerichtet um die zunehmenden Anfragen auf mehrere Datenbankserver zu verteilen. So kann die Performance des Datenbank-Clusters noch effizienter ausgenutzt werden.
Außerdem wurde ein weiterer Server eingerichtet um mit einem SOLR System die Suchanfragen zu optimieren. Durch die virtualisierte Umgebung konnte so ohne zusätzlichen Hardwareaufwand ein unabhängiger Server aufgesetzt werden, der bei Bedarf gut portierbar und skalierbar ist.
Erste Ergebnisse sind für beide Systeme positiv ausgefallen, so dass mit diesen Optimierungsmaßnahmen  das Weihnachtsgeschäft kommen kann.
