stackconf 2022 | Recap Day 1

stackconf is happening! Our first day of this year’s stackconf started with a wholesome breakfast in the Melia Hotel in the heart of Berlin. From the dining room we had a great view on the river Spree in the morning hours. After breakfast we were well prepared to listen to the first talks. Our CEO Bernd Erk was very happy to be able to welcome so many guests finally again in person. This wasn’t possible the year before because of reasons we know all too well. After two editions of stackconf online it felt good to meet in person

Check that Point!

One interesting guest was Adrian Reber presenting his project „Checkpoint and Restore in Userspace“ (CRIU) which might make live migrations of containers in Kubernetes an easy task in the future. With CRIU you can create checkpoints of containers which contain all data from the memory. In his live demo he went through the process of creating a checkpoint image of a container running in Kubernetes and pushing the checkpoint image to an container registry. Afterwards he created new containers from this image. There is still some manual work involved but the future goal is a „kubectl migrate“ command that makes it possible to live migrate containers to other nodes and to even have automatic scheduling of live migrations.

After Mr. Rebers talk it was time for lunch. We gathered at the dining room again and enjoyed our meals. Right after the lunch break it was time for some ignite talks. In one of them Daniel Uhlmann gave a short rundown of the basics of Site Reliability Engineering. For anyone interested, he recommended the free to read book (Site Reliability Engineering).

Philipp Krenn entered the stage after the ignite talkers and made the point (among others) that well structured health checks can still be very useful to detect failures in your systems. It doesn’t always need to be the observability approach.

A Good Corporate Citizen

Dawn Foster spoke about the „Dos“ and „Don’ts“ of contributing to open source projects as an employee of a corporation. After her talk in title „How to be a Good Corporate Citizen in Open Source“ a vivid discussion about the influence of profit-oriented corporations on non-profit open source projects emerged.

The second last talk of the day was held by Sebastian Saemann. He challenged the widespread notion of „Do not run stateful applications in Kubernetes“ by introducing the audience to Vitess – „a database clustering system for horizontal scaling of MySQL„. Mr. Saemann pointed out many advantages of running your MySQL databases in a Kubernetes Cluster with the help of the Vitess-Operator. In a live demo he also showed how easy it is to move a table from one database to a new database with zero downtime of the application.

Day 1 of stackconf will end with the evening event in the splendid Capitol Yard Golf Lounge. After dinner the attendees will let the evening come to an end with some drinks. I am already looking forward to it! As much as I am looking forward to Day 2. See you all tomorrow!

stackconf 2022 | Behind the scenes – Part 1/2 

stackconf 2022 is no longer just around the corner.

No – our long awaited conference will finally start tomorrow!


Berlin, here we go!

That’s why we have packed our things today to go to the location in Berlin. We have 16 people on tour supporting stackconf in different ways. The moderators, social media ladies, cameramen for the videorecordings, and many more.

The atmosphere on our bus is great. Everyone is looking forward to finally be part of an outstanding open source event this summer.


Our busy bees

While we are still on the way, our main organizers from the NETWAYS Event Team Markus and Lukas are already in Berlin and setting up the whole conference. The check-in counter, all the technique, the two conference rooms, the sponsors room, etc.. They are doing their best to provide you an absolutely exciting and smooth stackconf experience the next two days.



What will await you

This year’s stackconf is the first on-site edition of the conference. But this is just one aspect why we’re super excited about it. Furthermore, we have 30 international top-level speakers on board from well-known companies like Spotify, IBM, Intel, RedHat, Elastic, VMware and many more. They want you to get inspired by their expert lectures! Best case scenario: you go home with at least three new ideas to optimize your own infrastructure.


The whole crew is looking forward to get stackconf finally started. Everyone who is with us in Berlin: Have a nice evening and see you tomorrow at 9:00 am at our Welcoming session!

stackconf 2022 | Recap Day 2

After a good conclusion of the first day of stackconf with lots of laughter, good food and indoor golf we started the second day of stackconf with a talk by Dewan Ahmed on „Do NOT click-ops your data infrastructure„. Here he explained why you shouldn’t just click-op your applications infrastructure, because this can easily get you in trouble when scaling up. He talked about the basics to keep in mind with infrastructure code, such as reproducibility, repeatability and consistency. He explained the challenges and concerns regarding infrastructure as a code approach for data infrastructure. Challenges were also highlighted, such as Configuration Drift or Security Issues in public modules. As a solution to standardize infra code he presented Terraform and showed a detailed demo where he also explained the code.

It’s not about the tools. It’s about change. It’s about the people

The second talk was by Kris Buytaert about the last 13 years of DevOps. In a humorous talk he presented how not everything in the DevOps culture has changed for the better. He started with how chaotic some requests were in the old days and how short the deadline was, and how the DevOps culture has evolved from then to now. However, he also talked about how some great ideas have been destroyed by the industry, how tools don’t help with the wrong culture, and how some big companies pretend to be agile but aren’t. Also a problem he sees is how the title DevOps is being softened by misrepresentation from recruits and too many companies are simply issuing DevOps certifications but not passing on the mindset. The gist of his talk was that DevOps is not about tools, it’s about the people involved. It’s not about the tools. It’s about change. It’s about the people.

Dotan Horvits‘ third talk was about better observability with open source. Today’s monitoring world has the problem that it has to deal with large containerized environments such as Amazon or Netflix, where you need to monitor hundreds or thousands of services. Or services that are constantly being started, rescaled or stopped. In his talk, he goes into what Observability is and how it is defined depending on the requirements. He then goes into the three pillars of observability: Metrics, Logs and Traces. Afterwards he spoke about the most popular tools for the respective pillars, tools like Prometheus, Elasticsearch and Jaeger. Since tomorrow’s systems will continue to grow in complexity, I thought the talk was good because it points out future problems regarding monitoring and provides solutions on how to keep track of things despite a flood of tools.

Built a serverless application?

You know when you’re supposed to build a service and end up realizing that you’ve built a serverless application? That’s the situation JJ Asghar of IBM had, which was to build out the IBM Cloud. In his talk, he goes into how he initially built the backend for the IBM Cloud using Bash, then Ansible. He humorously discusses the failures you have on the way to the goal, the technologies used and explained some internal code.

After lunch, Laura Ham continued with an introduction to Vector Search with Weaviate. There she presented how Weaviate delivers semantic results using keywords and machine learning. To do this, the data objects are stored in the database, along with a vector specification. This allows the data to be displayed in a 3D grid. With the help of APIs, one can interact with the data. It was also shown how a search pipeline is structured and how Weavite handles it. Finally, Laura showed a demonstration where she had searched for results based on keywords from the full data set of the English Wikipedia, as well as an image search.

These were just a few of the talks presented at stackconf today. As with all good things, stackconf did come to an end. But the time was filled with laughter, many new contacts and a lively exchange of knowledge and ideas. I thought it was great to see many customers of ours there in person as well. My personal thanks goes to the speakers and everyone who had helped organize so that the event could run smoothly. Hope to see you all next year for stackconf 2023!
