stackconf wrap up – DAY 3

by | Jun 17, 2021 | stackconf

Day 3 was stackconfs last day, and my first day at the conference.


Datacenter on fire

Works on my machine - OPs problem now

Starting off with a meme about burning hardware!

Remember that story about the fire in the OVH Strasbourg Data Center from earlier this year? Kris Buytaert was one of the Engineers on call that night and in his talk he spoke about what it was like to be in the team that was there while the outage happened. He explains how they mitigated the damages and how they recovered from the incident. But he didn’t just talk about this specific incident, but also gave an insight on how to make your infrastructure secure, good business continuity plans and building cloud agnostic stacks that survive disasters.

In this context Christians burned PC also came up again – how does burning hardware come up in every conference?

The next talk was “Kubernetes Native Continuous Deployment with FluxCD, Flagger, and Linkerd”. Leonid Belkind and Or Elimelech from StackPulse decided to share their way of managing a Kubernetes native CD pipeline with the toolchain you can see in the title. If you feel like you would like some inspiration for building your own, then this talk is for you. They explain the pros and cons – the possibilities and limitations of each tool in their setup and how it all clicks together.

Sharing Open Source Spirit

The last talk before our coffee break has been my own: Contributing to Open Source with the example of Icinga. The main point of my talk was to invite everyone out there to help out the open source projects that spark your interest or you have been using for years! I showed you around in our repositories, on our website and forum. As contributing is a lot easier than one might think, my main goal is to take away some of the fear people in the community might have!

The coffee break itself was fun as always, with Christian and Bernd just chatting along, getting increasingly confused by the tabletop-games talk in the chat.


Right after we hopped into the talk by Michael Coté: Platform as a Product. He talked about how OPs can change the way they work to make life easier for everyone involved in devops and have everyones needs met. He gives some great ideas about how to innovate providing services and transforming away from a service delivery mindset to a platform-as-a-product approach.

On Twitter in the meantime, you can have some insights as to what is going on behind the screnes (or stream, rather).

Julien Pivotto gave us an extensive status update on Prometheus and what there is planned in 2021 and beyond. If you are using Prometheus or considering it, this might be the talk for you! A very in depth explanation on what it has to offer and what has changed in the recent past and a few tips and tricks on how to implement it properly!

Panel discussions

The hosts were joined by devops experts

I didn’t really sit in with Christian and Bernd for very long in the lunch break – they started off by chatting about snacks and I had to get some myself. Sadly the online conference doesn’t provide the usual snack buffet that you have in person…

When I rejoined the fun, Bernd and Christian were joined by a whole bunch of people for a panel discussion: there were Frank Karlitschek from Nextcloud GmbH, Kris Buytaert from Inuits.eu, Patrick Debois from Snyk, Rosemary Wang from HashiCorp and Serhat Can from Atlassian. A lot of well known organisations and people gathered to discuss all sorts of topics, from “What do you prefer: online vs in person conferences” over “How do we deal with the fact that former decentralised components have an outage” to “How can Open Source survive and be founded if traditional business models?” and “How to find the right balance between complexity and simplicity”.

Learning by doing

live coding

Adam coding live in his talk!

Adam Gordon Bell from Earthly talked about Learning by Pulling Things Apart – and in this case how to pull a container apart to understand how it works. A really nice intro into how the mechanics behind docker work and having a look from bottom up. A live coding session helped understand how to build up a container, which he also detailed in a blogpost that was shared in the chat.

Alberto Marti from OpenNebula spoke about GAIA-X and in his talk he analysed the benefits and challenges associated with Edge Computing, introduced the “True Hybrid Cloud” concept, and explored how this new EU-funded Edge Computing platform contributes to consolidate Europe’s digital sovereignty.

After another short coffee break Anjana Fernando from WSO2 Inc. picked up again with his talk about Microservices Observability with Programming Language: Ballerina. This was a topic that I found very interesting, as I haven’t even heard of Ballerina before. This talk was again centered around an extensive live coding / live demo session which we were walked through nicely.

Big Data and Machine Learning…

… are best when combined. The Weaviate Vector Search Engine aims to do exactly that – we were introduced to the inner workings of Weaviate by Laura Ham from SeMI Technologies with the example of finding the right wine for your seafood dish. Later in the talk we were shown how to actually work with the tool and received some super interesting explanation about how Weaviate connects data purely by proximity, so that it finds fitting results without the search term appearing anywhere in the result datapoint.

After a nice outro by Christian and Bernd we were left with a bit of an empty feeling, but looking forward to the next stackconf – hopefully all together with seeing each other and snacks in Berlin next year! Save the date for the next, stackconf, May 17 & 18, 2022 in Berlin.
