In the break room, attendees mingled and networked while enjoying a mouthwatering spread that included fruits, muffins, cakes, and puff pastries. The delightful food not only satisfied our taste buds but also added to the overall fantastic atmosphere. To be honest, we’re still missing those delicious bites!


Penguin Party

Guess who waddled back into stackconf 2023? That’s right, our adorable feathered friend from B1 Systems, the plush penguin! It seems we just can’t get enough of this fluffy fellow. But B1 Systems didn’t stop at penguin cuddles; they cranked up the coolness with an electrifying twist. Attendees once again had the chance to win an e-scooter in their awesome raffle. Our sponsors were awesome! Big shoutout to all our sponsors for making stackconf 2023 a wild ride!


Berlin is a cool place to be!

stackconf isn’t just about the conference itself; it’s also about the experience of being in Berlin. The vibrant capital city of Germany offers incredible opportunities for sightseeing, whether it’s exploring historical landmarks during the day or soaking in the city’s magical ambiance at night. It’s no wonder that attendees look forward to this added bonus each year.

stackconf 2023 | Recap Day 2

After a fun evening event filled with drinks, socializing, and even some roulette, hopefully everyone got some rest. Once that first cup of coffee kicked in, the attendees were ready to dive into the second day’s talks at stackconf 2023.


Let the Talks get started!

The first session in room Friedrichshain III of the hotel “NH Berlin Alexanderplatz” was held by Nicolas Fränkel, who works for Apache APISIX. He introduced the audience to the fundamentals of Observability in distributed microservice systems, which build on the three pillars of logging, metrics, and tracing. He showcased the OpenTelemetry framework, which has become a standard in the industry. As an example, he ran a webshop application programmed in Kotlin and showed the traces of HTTP requests visualized in Jaeger. He also briefly addressed how the OpenTelemetry libraries can be used in other programming languages like Rust or PHP.

Next up was Andrei Pokhilko of Komodor. He talked about the different network protocols used in microservice architecture and how to tune them for better performance. He mentioned some shortcomings of old, established protocols like HTTP/1.1 and the advantages of HTTP/2 or even the brand new HTTP/3. He showed some compelling results from comparisons of different protocols.

After that, Sayan Mondal of Harness took the stage. He is one of the maintainers of the CNCF incubating project LitmusChaos which he presented in a nice demo. LitmusChaos is a chaos enginneering platform that you can use to make your systems more resilient. The web interface is very intuitive. Check it out at https://litmuschaos.io/.

The last talk before the lunch break was held by Phil Williams of Canonical. He made an estimation of the cost of a  Ceph cluster running in a public cloud compared to a ceph cluster running on premise on your own hardware. The on-premise cluster costs 50% less in this estimation. At least for big ceph clusters (more than 1 Petabyte), Phil recommended running them on your own hardware.

Then the conference attendees sat down in the dining room to enjoy lunch. As on the first day, there were interesting ignite talks right after the lunch break. At the time of the writing of this blogpost the last talks were held, and the attendees were preparing to make their way back home.


It was a Blast!

As stackconf 2023 comes to a close, we’re grateful for the engaging talks and discussions on day two. We hope you leave with new insights and connections.

Thanks for being a part of stackconf 2023. Safe travels to all visitors, stay curious, and we’ll see you next year!

stackconf 2023 – Recap Day 1

We’re back again with two exciting days of knowledge-sharing, networking, and insightful conversations. This year, stackconf found its home in the vibrant city of Berlin, and it’s a pleasure to be back! Bernd set the tone for the event by extending a warm welcome to our eager attendees, ready to dive into the thought-provoking talks lined up for the conference. With both familiar faces and newcomers among our speakers, this year’s event promises fresh perspectives and engaging discussions.

Here are a few of the talks that stood out for me today. You can find the other presentations from our speakers and their profiles on our homepage or in the event app.


Scaling a Collaboration Service like Nextcloud to 20 Million users with Frank Karlitschek.

The day began with a captivating talk by Frank on the exciting world of Nextcloud AI. Frank gave us a sneak peek into the next update, highlighting the seamless integration of AI tools. What’s unique about this integration is that it’s localized on your server, keeping your data secure. Frank’s talk covered a range of applications, from writing headlines and summarizing emails to generating images and transcribing speech to text. The promise of a Nextcloud assistant AI on the horizon adds to the anticipation of what’s to come.


Open-Source: Open Choice – A DevOps Guide for OSS Adoption with Hila Fish

The second talk addressed a common challenge for many, selecting the right open-source project for their environment. Hila shed light on the DevOps perspective of open-source, emphasizing the importance of aligning an OSS project with your specific needs and pain points. With practical advice and insights, the talk guided attendees on how to evaluate key indicators and make informed choices, saving valuable time and resources.


Acknowledging Our Sponsors

Before we continue, we’d like to extend our heartfelt gratitude to our generous sponsors. Their support has been instrumental in making this conference possible. We truly appreciate their contributions, and their commitment to our community is invaluable. Thank you!


GitOps in Kubernetes with Alex Soco.

Alex’s presentation talked about a popular open-source GitOps Kubernetes Operator, ArgoCD. He explained how ArgoCD leverages the GitOps pattern to define application states through Git repositories. This simplifies Kubernetes management by automatically syncing Kubernetes manifests to target clusters, ensuring they remain in the desired state. It’s a valuable tool for streamlining Kubernetes operations.



As the day drew to a close, attendees not only had their minds enriched with knowledge but also their appetites satisfied with sumptuous food. The quality of the speakers left everyone looking forward to the rest of the conference. But that’s not all; the evening event promises to be a memorable one, featuring our renowned party with roulette—a fantastic opportunity for networking, relaxation, and fun.


In Berlin, we’re not just about sharing insights; we’re also about creating lasting memories. Stay tuned for more updates from the Berlin conference as we continue our journey of discovery, learning, and celebration.
