Liebe Hauptstadt-Monster, im April spricht Daniel Lindemann über die „schöne neue Welt“: Datenbanken in gemanagten Kubernetes-Clustern in der Cloud. Egal ob alter On‑Prem‑Hase oder neuer Cloud‑Aficionado: wir sind sicher, dass Daniel für alle erhellende Einsichten mitbringen wird. Kommt vorbei, oder [guckt wenigstens auf Teams zu](https://teams.microsoft.com/meet/3267619397268?p=Gg5dLAdbLC6qZskGH0 )! Wir freuen uns auf euch! Markus & Ben ## Deploy, connect, fertig: AKS und Datenbanken in der Praxis In dieser Session wird gezeigt, wie du mit Azure Kubernetes Service (AKS) schnell und praxisnah in Kubernetes einsteigst. Anhand von Live-Demos siehst du, wie containerisierte Anwendungen deployt und betrieben werden. Der Fokus liegt auf der sicheren Anbindung an Datenbanken. Du lernst, wie deine Anwendungen zuverlässig und sicher auf Daten zugreifen, z. B. über Managed Identities, Secret Management und Azure-Integrationen wie den Key Vault. Perfekt für dich, wenn du Kubernetes und AKS nicht nur verstehen, sondern direkt sinnvoll mit echten Daten einsetzen willst. ## Daniel Lindemann  Daniel Lindemann ist Entwickler und Consultant bei der abtis GmbH in Pforzheim. Er ist spezialisiert auf das Entwickeln von modernen Lösungen mit cloud-nativen Ansätzen, weshalb er sich für die Themen Serverless- und Container-Architekturen in Microsoft Azure begeistert. Getreu dem Motto “Wer es baut, der betreibt es auch.” unterstützt er Anwendungsentwickler auch in den Bereichen IT-Infrastruktur, Automatisierung und DevOps.

**⚠️ IMPORTANT: REGISTRATION MANDATORY ⚠️** Registration on **Luma** is **REQUIRED** to attend this event. **Link: https://luma.com/q57evozo?utm_source=meetup** Your registration is subject to host approval. You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x dida** workshop featuring **Elias Trommer** from **Infineon**, who will guide us through an interactive session on Embedded AI. ​​​ **Title:** Deep Learning Models on 5€ microcontrollers 📅 **Date:** 29.04.2026 🕕 **Time:** 18:00 📍 **Location:** TU Berlin Marchstrasse 23 [Room 0.011] ​​​The session will last around 2 hours, followed by a networking session with **dida** and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! *** ​**Abstract**: In this workshop, we will discuss the unique challenges (and solutions) faced when deploying Deep Learning models to embedded microcontrollers. These tiny devices are increasingly capable of running models, even for relatively complex use cases, but come without many of the comforts of a classic computer. When deploying a model to a microcontroller, a much deeper understanding of the physical hardware and good knowledge of the various optimization paths that help reduce the resource consumption of an application is needed. We aim to shed some light on how to deploy models to these cheap, ubiquitous and sometimes surprisingly capable little pieces of hardware. ​**In this session, we will cover:** * ​Important differences between a desktop/server and a bare-metal embedded system * ​Quantization for model compression * ​Anatomy of an Embedded Application * ​Embedded ML Inference Engines and how to run them * ​Deploying a model step by step ​**Who is this event for?** This session is targeted at anyone with basic ML knowledge. Experience with C and embedded systems is probably helpful, but not required. We will cover the most important aspects as part of the workshop. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

Are you keeping up with how fast AI is changing the way we work? We are in the midst of understanding how AI is reshaping our roles, workflows, and what is possible in product development. The pace of change is rapid, and many managers are actively experimenting and learning as they go. We’ve invited two experienced product practitioners to share their hands on experience and learnings: **Daniel** will focus on how AI can be used to increase personal leverage and productivity as a product manager. **Ruslan** will share his experience with turning AI prototypes and real products. This event is designed for hands-on product managers and product builders who want to improve their workflows and rethink how products are built within their organizations. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov 19:40 – Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev 20:10 – Networking 21:30 – Event ends **Please note:** * **Please bring your IDs as you’ll need it when entering the venue.** * The event is RSVP only: to enter, you must RSVP here on Meetup. * We'd like to capture the event with photographs for promotional purposes, such as sharing on LinkedIn after the event. If you have any concerns or preferences regarding this, please feel free to let us know beforehand. **Demystifying AI: A Productivity Playbook for Product Managers, Daniel Zherenkov** To harness the power of AI, you first need to understand it. Join this session to strip away the FONO tropes from LinkedIn and understand the reality of today's AI capabilities. We will explore practical frameworks for integrating AI into the product management daily life, empowering you to make better decisions, streamline workflows, and build superior products. About the speaker: Daniel, ML/AI Product Manager at Delivery Hero with 8+ years of experience in creating ML and AI products, will explain what AI actually is and how to squeeze the maximum efficiency from it based on the real examples that could be reproduced by anyone. **Building with AI: How Smart Prototypes Become Real Products, Ruslan Vorobev** The talk looks at how AI can turn quick prototypes into real, valuable products. Ruslan shares practical lessons from using tools like Lovable, GPT, and internal automations to move from idea validation to production-ready solutions. The focus is on finding where AI truly adds value, whether through lightweight assistants or deeper integrations, and where it’s better left out. About the speaker: Ruslan Vorobev is Head of Product with a strong focus on innovation and AI-driven solutions. He has overseen product and business development across sustainability, circular economy, and manufacturing domains, helping scale digital products from early prototypes to market-ready solutions. His work combines hands-on experimentation with practical automation to turn ideas into tangible impact.

**Nebius.Build/BER** is a technical in-person event for engineers, architects, founders, and developers building, deploying, and scaling AI systems in production.
