Join our next meetup at Collibra on June 4th! We will have 3 talks about OpenTelemetry and will share some food and drinks while networking **Location:** Collibra, Rue Picard 11, 1000 Bruxelles **Agenda:** 17:45 : Doors open 18:00 - 18:30 : Drinks and pizza 18:30 - 19:10 : Talk #1 OpenTelemery on Kubernetes with EDOT: Getting started and what's ahead 19:10 - 19:50 : Talk #2 Taming Tenancy, Cost and Architecture at Collibra Through OpenTelemetry and Our Telemetry Backbone 19:50 - 20.30 : Talk #3 Closing the Observability Gap: OpenTelemetry Meets Elastic at Telenet 20:30 : Wrap up **Talks:** **#1 OpenTelemery on Kubernetes with EDOT: Getting started and what's ahead** **OpenTelemetry has become the default way to instrument applications and infrastructure, and Kubernetes is one of the places where it makes most sense to use it.** This talk is a tour of OpenTelemetry on Kubernetes, focusing on the Elastic Distribution of OpenTelemetry (EDOT). We will explore the OTel basics (general architecture, signals) and the recommended way to deploy OTel on Kubernetes using the OpenTelemetry Operator. A live demo with an Elastic backend will showcase the correlation of metrics and logs, demonstrating how everything ties in together. Finally, it will cover the current community effort to stabilize Kubernetes observability, including the promotion of Kubernetes attributes to release candidate status and the latest updates to the semantic conventions for Kubernetes metrics. This session is useful for beginners trying to get into OTel, and for those running OTel in their Kubernetes cluster and trying to get some insights on what is to come. *Speaker: João Marques Correia, Software Engineer at Elastic* **#2 Taming Tenancy, Cost and Architecture at Collibra Through OpenTelemetry and Our Telemetry Backbone** Operating a SaaS platform presents the same observability problems as any other enterprise, but due to the scale and tenancy, we introduce a huge multiplier on the observability signals, having an effect on cost and effectiveness. This session dives into the techniques Collibra used to tame these problems and how to maintain clarity when infrastructure spans virtual machines, modern Kubernetes clusters, and a complex mix of single- and multi-tenant architectures. Without the right context, telemetry data becomes a noisy, indistinguishable flood. We will dive into the architectural decision to leverage the C4 system model, ensuring every piece of telemetry carries the vital context of what it belongs to and where it sits in the hierarchy. Enabling us to gain insights into both signal attribution and allowing virtual chargebacks. The presentation details the implementation of a pipeline using custom-built OpenTelemetry collectors designed to handle the data and enrich it before sending it to the appropriate backends. This session will give you practical insights on the challenges SaaS platforms have, but the techniques that are used to tame them can be applied everywhere. *Speaker: Alex Van Boxel, Principal System Architect at Collibra* **#3 Closing the Observability Gap: OpenTelemetry Meets Elastic at Telenet** Modern systems generate more telemetry than ever, but without consistency, that data quickly becomes noise. At Telenet, we turned to OpenTelemetry to standardise how we collect and enrich observability data across our bare-metal Kubernetes clusters. This talk dives into how we integrate OpenTelemetry into our engineering workflows and couple it with Elastic for storage, analysis, and visualisation. We’ll walk through our architecture, instrumentation strategies, and how we ensure high-quality telemetry that engineers trust. Along the way, we’ll highlight real use cases, from debugging production incidents to improving service performance, and discuss what worked, what didn’t, and what we’d do differently today. If you're an Elastic user looking to adopt or scale OpenTelemetry, this session will help you bridge the gap between theory and practice. *Speaker: Reidar Veroft, Container Platform Engineer at Telenetgroup* **Bios** **Alex Van Boxel** is a Principal System Architect at **Collibra**. With an engineering background in Research and Development at Alcatel-Lucent, Progress Software, and Veepee he loves to focus on the fundamental building blocks of the software industry. That means reading, understanding, and contributing to specifications, as well as contributing to the Open Source projects that run through our infrastructure. He is code-owner of two components of the OpenTelemetry collector. **João Marques Correia** is a Software Engineer at **Elastic**. Having recently joined Elastic, he has been focusing on OpenTelemetry, with a bigger effort being put into Kubernetes metrics stabilization. Before joining Elastic, he worked as a Software Engineer at Cisco on a Data Center network controller. He is drawn to distributed systems, and in particular how to observe them and keep them working reliably. **Reidar Veroft** is a DevOps Engineer at **Telenet**, where he builds observable, reliable systems that power critical infrastructure across Belgium. From the 5G core to our voice core, he focuses on making sure the systems behind Telenetgroup are not only running, but fully understood through high-quality telemetry. **Thanks to Collibra for hosting this meetup!**

**Welcome to the Sixth BDEN Meetup!** AI is moving fast, and developers are right in the middle of it. Some are already experimenting with AI-assisted coding, agents, MCP servers, and local models. Others are still trying to understand what all these new concepts really mean and where to start. This meetup is designed for both. For our sixth Belgian Developer Experience Network meetup, we will focus on what AI means for developers today: how agentic systems are built, how they can be used safely, and what it takes to bring them closer to production in an enterprise context. As always, expect more than slideware. We will have explanations, demos, real-world discussion, and enough space for questions and networking. Mark your calendars for the 4th of June, because it is going to be an evening packed with practical insights into AI, agents, developer workflows, and production readiness. **Location** This meetup will take place as part of Red Hat Tech Day Belgium, hosted at The Montil in Affligem. Red Hat Tech Day is a one-day conference for both technical and non-technical audiences. This year, for the first time, the event will also include a dedicated developer track, focused on the latest technologies and methodologies from the AI and software development communities. You are also welcome to register for the full event here: https://reg.experiences.redhat.com/flow/redhat/3977379/fieldeventsregapproveform/page/landingregistrationpage **Schedule** 17:00 - 18:00 Doors open 18:00 - 18:15 Intro session 18:15 - 19:15 AI agents, skills, demos and sandboxing 19:15 - 19:30 Break 19:30 - 20:30 Panel discussion: putting agentic AI in production 20:30 - 22:00 Networking & food **Sessions** **Session 1: AI agents, skills, demos and sandboxing** **Speaker:** Burr Sutter, Director of Developer Experience at Red Hat **Description:** AI is no longer just about sending prompts to a chatbot. Developers are now exploring skills, agents, tools, MCP servers, and workflows where AI systems can take action instead of only generating text. In this session, Burr Sutter will explain what skills and agents are, how they work, and why they matter for developers. Through demos, he will show how these concepts are implemented and defined within Red Hat, and how agentic systems can be sandboxed with technologies such as OpenClaw. Whether you are new to AI or already experimenting with agents in your own workflow, this session will help you connect the concepts to practical developer use cases. **Session 2: Panel discussion: putting agentic AI in production** **Panel participants:** Burr Sutter, Director of Developer Experience at Red Hat Stephan Janssen, founder of Devoxx and organizer of Devoxx Belgium One mystery guest, to be announced later this week **Description:** Building a demo with AI is one thing. Putting AI, and especially agentic AI, into production is something else. After a short break, we will continue with a panel discussion on what it takes to use AI safely and effectively inside an organization. We will discuss how to get started, what developers should keep in mind, what organizations need to prepare for, and how to think about governance, security, reliability, and platform support. The panel will bring together different perspectives from developer experience, AI-assisted software development, enterprise readiness, and the changing role of developers in the age of intelligent systems. This panel is for developers who are curious about AI, developers already using AI tools, and teams wondering how to move from experimentation to real adoption. **About Stephan Janssen** Stephan Janssen is the founder of Devoxx and organizer of Devoxx Belgium. In recent years, his work has focused heavily on LLMs, AI-assisted software development, and Agentic Engineering. He actively explores technologies such as local and cloud-based LLMs, multi-agent systems, MCP, RAG, Spec-Driven Development, and AI-powered developer workflows. Stephan is also the creator of DevoxxGenie, an open-source IntelliJ IDEA plugin that enables developers to interact with local and remote LLMs directly from their IDE. Through talks, workshops, and R&D projects, he focuses on how AI agents are transforming software engineering and how developers are evolving from traditional coders into orchestrators of intelligent systems. More info: [https://stephanjanssen.be](https://stephanjanssen.be/) **About Philippe Bogaerts**: And our next panel speaker is Philippe Bogaerts. Philippe is co-founder and organizer of BruCON, and an enthusiastic researcher and trainer in the world of building, securing, and hacking agentic systems. He is also a wonderful public speaker. Philippe has already presented twice at BDEN, and every time he brings exactly the kind of energy we love: hands-on, practical, sharp, and anything but boring slideware. It is a pleasure to see him explore, break, test, and hack in the agentic AI space. He is one of those speakers who keeps you interested from the first second to the last, because he does not just talk about the topic. He actually gets his hands dirty. With Philippe joining Burr Sutter and Stephan Janssen, this panel is shaping up to be something special. Really looking forward to this one. **Additional note** ***This meetup includes food. Please keep your RSVP status up to date so we do not waste any food. In case you are no longer sure you can join in person, please update your RSVP accordingly.***
