OSMC 2018 – or: The Thirteen-Star Conference

“How many stars do you have?” – Just take a look at the name tag, count the stars and you’re talking. At a lot of participants badges you’ll see a considerable number of them. Once you’ve been to OSMC, you usually come back. Why is that so? Here’s what I found out:
My first conversation partner is a big catch: 13 stars – 13 years of OSMC! Stefan Kublik arrived from Neckarsulm and is taking part for Fujitsu TDS GmbH. To the first conferences, at that time still Nagios, he went for another employer. He changed companies, OSMC remained. What Kublik particularly appreciates: “Many people here are working on the same problems. The OSMC is great to get an overview.” Where is the community standing? Where is the journey going? Thruk and Prometheus interest him, the products he uses himself. But Kublik also picks up on new topics and continues researching at home. What has changed over the years? OSMC has become more international, he says. Will he come again? “I have to! The series of stars can’t stop! As long as I work in this field, I will come back!”
Two stars: For the second time Kevin Honka is at the OSMC. For his first he has actually been here as a speaker. “I was relatively active in the monitoring portal,” he says. And so he was asked if he would like to report about his activities at the OSMC. “Now I come to every Icinga camp and of course to the OSMC.” He is interested in Icinga, Graylog, Git, virtualization techniques… What he appreciates the most? “The people. And the food,” he says with a grin. And he adds: “I have seldom had better technical discussions.
Ulrike Klusik has only been working in monitoring for three quarters of a year – but OSMC already has her! Thanks to her boss at ConSol Consulting & Solutions Software GmbH. Klusik thinks the conference is above all a good opportunity to get to know Open Source tools. Besides the ones she knows already – OMD, which they develop themselves, and OpenShift and Prometheus. “I found the lecture on Sensu very interesting,” she says, “or: Oberservability in einer Microservicewelt”. As a newcomer to monitoring, she is particularly interested in lectures on general procedures. She thinks it’s worth coming back: “It’s good to look beyond one’s own nose. Unfortunately, one often has too little time for this in everyday work.”
Christian Hager counts and is astonished himself: “Ten stars! “In the beginning I came because I wanted to know something about monitoring with Nagios and Icinga. Now I come for everything else,” he laughs. Smart Home, Refocus, Maps, SLA Monitoring he has joined. When I ask him what else he is interested in, he pulls out a small notebook. This man is prepared! Hager has made a plan for both days. All the more flexible he is during the breaks. “I like to sit down with people I don’t know. That gives me new ideas.” Other conferences may be bigger, but there are many more sales people on the road. “The OSMC gathers a good group of experts, and it’s easy to find specialists to talk to here.” Hager himself comes from the computer centre at the University of Würzburg.
I meet Holger Koch and Gudrun Schöllhammer at a bar table in front of room Jacobi. They talk to each other. He joins for DB Systel GmbH from Erfurt, she comes from the University of Vienna. Eight OSMC stars are emblazoned on his name tag, six on hers. “We see each other here once a year,” she says – and he: “The OSMC is like a class reunion.” Unfortunately, we don’t get any further: The next talk begins. The two have a well clocked schedule. Apart from the good conversations with other admins, they are mainly on the hunt for input. Well, then I don’t want to stop them!

Have fun at the OSMC 2018!

And save the date for next year’s OSMC, November 4 – 7, 2019!

The Future of Open Source Data Center Solutions – OSDC 2018 – Day 1

Now for the fourth time OSDC started in Berlin with a warm Welcome from Bernd and a fully packed room with approximately 140 attendees. This year we made a small change to the schedule by doing away with the workshop day and having an additional smaller conference afterwards. The Open Source Camp will be on Foreman and Graylog, but more on this on Thursday.
First talk was Mitchell Hashimoto with “Extending Terraform for Anything as Code” who started by showing how automation evolved in information technology and explained why it is so important before diving into Terraform. Terraform provides a declarative language to automate everything providing an API, a plan command to get the required changes before you then apply all this changes. While this is quite easy to understand for something like infrastructure Mitchell showed how the number of possibilities grew with Software-as-a-Service and now everything having an API. One example was how HashiCorp handles employees and their permissions with Terraform. After the examples for how you can use existing stuff he gave an introduction to extending Terraform with custom providers.
Second was “Hardware-level data-center monitoring with Prometheus” presented by Conrad Hoffmann who gave us some look inside of the datacenter of Soundcloud and their monitoring infrastructure before Prometheus which looked like a zoo. Afterwards he highlighted the key features why they moved to Prometheus and Grafana for displaying the collected data. In his section about exporters he got into details which exporter replaced which tools from the former zoo and gave some tips from practical experience. And last but not least he summarized the migration and why it was worth to do it as it gave them a more consistent monitoring solution.
Martin Schurz and Sebastian Gumprich teamed up to talk about “Spicing up VMWare with Ansible and InSpec”. They started by looking back to the old days they had only special servers and later on virtual machines manually managed, how this slowly improved by using managing tools from VMware and how it looks now with their current mantra “manual work is a bug!”. They showed example playbooks for provisioning the complete stack from virtual switch to virtual machine, hardening according their requirements and management of the components afterwards. Last but not least for the Ansible part they described how they implemented the Python code to have an Ansible module for moving virtual machines between datastores and hosts. For testing all this automation they use inSpec and the management requiring some tracking of the environment was solved using Ansible-CMDB.
After lunch break I visited the talk about “OPNsense: the “open” firewall for your datacenter” given by Thomas Niedermeier. OPNsense is a HardenedBSD-based Open Source Firewall including a nice configuration web interface, Spamhouse blocklists, Intrusion Prevention System and many more features. I think with all these features OPNsense has not to avoid comparison with commercial firewalls and if enterprise-grade support is required partners like Thomas Krenn are available, too.
Martin Alfke asked the question “Ops hates containers. Why?” he came around in a customer meeting. Based on this experience he started to demystify containers in a very entertaining and memorable way. He focused on giving OPS some tips and ideas about what you should learn before even thinking about having container in production or during implementing your own container management platform. As we do recording I really recommend you to have a look into the video of the talk when recordings are up in a few days.
Anton Babenko in his talk “Lifecycle of a resource. Codifying infrastructure with Terraform for the future” started were Mitchell’s talk ended and dived really deep into module design and development for Terraform. Me being not very familiar with Terraform he at least could convince me that it seems possible to write well designed code for it and it makes fun to experiment and improve with your own modules. Furthermore he gave tips for handling the next Terraform release and testing code during refactoring which are probably very useful for module authors.
“The Computer Science behind a modern distributed data store” by Max Neunhöffer did a very good job explaining theory used in cluster election and consensus. The second topic covered was sorting of data and how modern technology changed how we have to look at sorting algorithm. Log structured merge trees as the third topic of the talk are a great way to improve write performance and with applying some additional tricks also read performance used by many database solutions. Fourth section was about Hybrid Logical Clocks to solve the problem of system clocks differing. Last but not least Max talked about Distributed ACID Transactions (Atomic Consistent Isolated Durable) which are important to keep data consistent but are quite harder to achieve in distributed systems. It was really a great talk while only covering theoretical computer science Max made it very easy to understand at least basic levels and presented it in way getting people interested in those topics.
After this first day full of great talks we will have the evening event in a sky bar having a good view of Berlin, more food, drinks and conversations. This networking is perhaps one of the most interesting parts of conferences. I will be back with a short review of the evening event and day 2 tomorrow evening.
