Hosted by Zalando Sponsored by incidentist.io (and last year by SOK.fi) **Agenda** 17:00 Doors open 17:30 Welcome / DevOps Finland & Zalando 17:45 A perfect storm: how a tiny change in a CMS service authentication once broke up the Zalando Fashion Store? / Uri Savelchev, Senior DevOps Engineer @ Zalando Finland 18:30 \*\*\* break \*\*\* 18:45 Start SLOw! - How to ru(i)n your services using Service Level Objectives / Vitek Urbanec, Chief Resiliency & Governance Consultant @ incidentist.io 19:30 Free discussion 20:30 Doors close **A perfect storm: how a tiny change in a CMS service authentication once broke up the Zalando Fashion Store?** Is it possible that a little mistake in update of a CMS, that is pretty far from the "hot path" and the customer traffic, could break up the operations and lead to a high-profile incident? I'll tell you a thrilling story about one of the most puzzling incidents I have ever dealt with. For the last fifteen years I'm specializing in DevOps/SRE and Platform Engineering. **Start SLOw! - How to ru(i)n your services using Service Level Objectives** In the vibe-coded world, it's essential to know when your change broke your company's stream of income (again), and how much more of that can your customers take before they vibe-code their own SaaS (with blackjack & webhooks). Calculating good_events / total_events \* 100% is just the beginning. You've done the calculation, you've set a made-up arbitrary objective, but what do you do next? In this talk, we dig beyond the trivial topics, our starting line will be "we already have the SLOs, what now?" Vitek Urbanec is a Chief Resiliency & Governance Consultant at incidentist.io, who has spent the better part of 13 years making sure other people's production systems don't catch fire — and occasionally helping them understand why they did. He's worked across industries in fintech, gaming, and SaaS, most recently embedded with a platform team, helping squads turn uptime feelings into actionable SLOs. **Streaming:** https://app.sli.do/event/4456cs3cfWgSemSQaYXVm4 **Join our Slack and other channels:** https://www.devopsfinland.org/ **LinkedIn:** https://www.linkedin.com/company/102919614

Welcome to join our Sahaja Yoga meditation meetings in English! The meetings are free of charge and you can just show up. The group consists of people of different ages and nationalities who have been meditating different periods of time. Newcomers are welcome at any time. We normally sit on chairs or on pillows on the floor, so there is no need to bring a mat and you can wear normal clothes. Meditation means mental silence or thoughtless awareness. You are present here and now, but your mind is not bombarded by thoughts from the past or the future. In this state, you feel peace and joy, which are the essential elements of the present moment. With regular practice of meditation, it is possible to establish this state within us. The group is lead by volunteers who are experienced and can offer guidance to get you started. We give a short introduction to the meditation and after that we do meditation exercises. We also give tips on how to meditate at home. After the meditation class, we have a cup of tea and there is time for questions. Welcome! We hope to see you in our meditation meetings!

If you are noise sensitive, bring earplugs/headphones etc.. There’s no pressure to share your work unless you feel like it — you’re always welcome to keep things private. All kinds of writing are welcome: – Creative writing – Poetry – Journaling – Essays or academic work – Anything else Any language is welcome too.

Welcome to our **April** meetup hosted in collaboration with the non-profit **[Founders House Helsinki](https://founders-house.fi)** and **[CRACI](https://craci.com/)**. CRACI will sponsor the food and drinks, thank you! Schedule: **17:00 Doors open** **17:00 - 17:45** **Networking** **17:45 - 18:00** **Host & organizers - Welcome and practicalities** **18:00 - 18:30** **Software Supply Chain Attack Vectors when using Generative AI, by** **Erika Marttinen, Software Engineer, CRACI** **18:30 - 19:00 Break, networking** **19:00 - 19:30** **Right-sized Kubernetes Access Control with Conditional Authorization, by Lucas Käldström, Kubernetes contributor, Upbound** Have you ever struggled writing least-privilege access control policies for Kubernetes? Are you concerned about the wide permissions of installed Helm charts? Do you manage to regularly audit who has access to sensitive resources? In this talk, Kubernetes contributor Lucas introduces you to open source tools that help you on your defense in depth journey for securing the Kubernetes API surface. They demonstrate how to right-size your RBAC rules semi-automatically, audit who can access sensitive resources, and check whether policy refactors are correct. This talk is part of a journey to improve Kubernetes access control in core. However, to make this initiative successful, user feedback is needed throughout the process. You’ll learn about the planned Kubernetes Conditional Authorization feature, which will make authoring right-sized policies easier. **19:30 - 20:00 Break, networking** **20:00 - 20:30: The LLM Gateway Is an Ingress Controller. Treat It Like One, by Juan Antonio Osorio, Software Engineer, Stacklok** The AI gateway has quietly become the most valuable credential aggregator in the enterprise. One process holds OpenAI, Anthropic, Bedrock, and Gemini keys for every team. The March 2026 LiteLLM TeamPCP supply-chain compromise showed what that costs: one backdoored PyPI release, every credential in the gateway exposed in minutes. This talk is about what you do before that lands. Every LLM gateway is an ordered pipeline, and the security of the pipeline is a property of its ordering, not of any individual stage. The worked example is upstream Envoy AI Gateway (CNCF project under the Envoy umbrella); the lens applies to any gateway that fronts LLMs. **20:30 - 21:00 Networking** **NOTE:** The event will be live-streamed on the Cloud Native Nordics YouTube. **NOTE:** Signing up for the event gets you a seat at the onsite event. **NOTE:** Pictures might be taken during the event and be published to this meetup page. Also there will be a livestream during the event which picks up audio from the space. If you do not want to be included in any pictures, please let the organizers know.
