Stop Building AI Models. Start Building AI Products - From Demo Applause to Production Value

Fabrizio Lazzaretti

  • 30min Talk
  • AI, ML & Big Data
  • People & Experiences

95% of GenAI projects fail to deliver measurable business returns (MIT Media Lab, 2025). Not because the models don't work—they demo beautifully. They fail because we skip the fundamentals: clear requirements, stakeholder alignment, and product thinking. This talk challenges the "build a model first" mindset. We'll explore why requirements engineering and understanding business value are more critical for AI projects, not less. You'll learn practical techniques to identify real value and collaborate effectively with stakeholders—defining success before writing a single line of code. With this foundation, we examine when PoCs are actually needed and how to bridge the dangerous gap between PoC and MVP. But we don't stop there: What does a real product strategy look like? How do we move from one-off experiments to a systemic, transformational approach? This talk will help you think about getting value out of solutions—where AI is a powerful tool to achieve outcomes, not the business value itself.

  • People & Experiences

Managed Kubernetes doesn’t eliminate complexity, it shifts it out of sight. In this talk, we look behind the curtain of Managed Kubernetes to show the architectural building blocks that enable Managed Service Providers (MSPs) to deliver production-ready clusters for customer workloads. We will walk through different patterns for control plane hosting and node lifecycle management, comparing practical approaches from open source projects like Gardener, Kamaji, and Cluster API. The session closes with a live Gardener demonstration, illustrating how the "Kubernetes on Kubernetes" model can support high-density multi-tenancy, control plane isolation, and resilient lifecycle automation.

From Automation to Context-Aware Delegation - How to become the 5%

Sebastian Kister

  • 30min Talk
  • Platform Engineering
  • People & Experiences

According to Gartner, 95% of enterprise AI initiatives fail - not because of the technology, but because organizations lack the cultural, operational and contextual foundation to make AI work in production. This session shows what it takes to be part of the 5% that succeed - real, deployed, hands-on. No buzz words, no myths, no false promises. We’ll explore the shift from scripted automation to context-aware, agentic delegation, where systems understand environments, dependencies, and intent. By embedding context into neural networks and context graphs, we move from maintaining scripts to delegating outcomes - enabling deterministic, auditable, and resilient automation across any infrastructure, including air-gapped systems. Using real examples from platform engineering and enterprise operations, we’ll demonstrate how context-aware automation might reshape open source adaption and the entire cloud-native ecosystem. Don’t be fooled: success takes more than just tech - it requires a mindset-shift, governance, and a culture ready to rethink everything that they've learned. Forget your current "now" and take something home that helps you with your decision making - especially if you're desperate about bringing your automation-KPI up.

Agentic AI Under Attack: Live Demos of Exploits Through Autonomy and Trust

Nico Meisenzahl

  • 45min Deep Dive
  • Network & Security
  • AI, ML & Big Data

AI agents are making decisions, calling tools, and trusting data, all without human review. But with autonomy comes a new and largely misunderstood attack surface. In this demo‑driven talk, we’ll show how agentic AI systems can be hijacked without code exploits. Using nothing but text, tools, and trust. Through live demos, we explore three real‑world classes of vulnerabilities from the OWASP Top 10 for AI: - Indirect Prompt Injection, where untrusted content silently manipulates agent decisions - Tool / MCP Poisoning, where malicious tool descriptions hijack agent behavior and leak full context - RAG Poisoning, where internal knowledge causes persistent data exfiltration No slides. No theory. Just Demo, Demo, Demo! With practical DevSecOps lessons on why classic security controls fall short once AI agents start acting on your behalf.

You Call That an AI Agent?

Krisztián Papp

  • 30min Talk
  • AI, ML & Big Data

“AI agent” has become an overloaded term, applied to everything from glorified cron jobs to brittle prompt chains. In this talk, we challenge the hype and ask a simple question: what actually qualifies as an AI agent? We’ll break down common misconceptions, examine real-world implementations, and contrast agent-like systems with workflows, automations, and orchestration pipelines that are often mislabeled. Through concrete examples, we’ll explore autonomy, planning, memory, feedback loops, and failure modes, and show where most systems quietly fall short. The goal is not to define yet another framework, but to give practitioners a clear mental model to reason about agents, avoid architectural self-deception, and build systems that deserve the name.

Broadcasting Deployments: ORF's Journey to Bulletproof Kubernetes Releases

  • 45min Deep Dive
  • Kubernetes & Container
  • Platform Engineering
  • Developer Experience
  • Operations & Performance
  • People & Experiences

Modern cloud-native development demands deployment pipelines that empower developers to ship with confidence while maintaining rigorous governance across environments. This session presents a comprehensive, production-proven deployment architecture that transforms multi-stage Kubernetes releases from operational burden into seamless automation. At the core of our approach lies a GitOps-driven pipeline integrating Release-Please for automated semantic versioning, GitHub Actions with reusable workflows for CI/CD orchestration, and ArgoCD's multi-source capabilities for declarative Kubernetes deployments. Each release generates cryptographically signed container images and Helm charts, complete with SLSA attestations, ensuring supply chain integrity from commit to production. The architecture addresses a critical challenge in enterprise environments: decoupling application versioning from infrastructure configuration. By leveraging ArgoCD's multi-source applications, teams independently manage Helm chart versions and stage-specific value files, enabling granular control over what deploys where and when. Renovate automates dependency discovery across all layers, including container images, Helm charts, and configuration manifests, creating pull requests that serve as auditable promotion gates between development, staging, and production environments. We demonstrate practical use cases including automated image updates with configurable auto-merge policies, timestamp-tagged configuration releases for deterministic deployments, and coordinated multi-artifact rollouts. The result: a scalable, standardized deployment framework that reduces cognitive overhead for development teams while providing platform teams with the governance and traceability required for enterprise Kubernetes operations.

AI Made Us Faster at Solving the Wrong Problems

  • People & Experiences

You are in a meeting. Someone checks their Generative AI of choice mid-discussion and announces: "The AI says we just need to do X." Everyone nods and moves on. Congratulations, you have just solved the wrong problem. Nothing is broken. Everything is faster, and yet something is wrong. Generative AI has amplified our worst problem-solving habit: jumping to solutions before understanding the problem. It is System 1 thinking on steroids, magnified by the Dunning-Kruger effect: confident, fast, and increasingly wrong. We are racing toward solutions faster than ever, but they are brittle, disconnected, and often miss the point entirely. This talk will teach you that one question changes everything: "What problem are we actually solving?" It sounds simple. It is not. You will learn how to recognize when speed is hiding misunderstanding, how to distinguish symptoms from root causes, map consequences before committing, and slow down long enough to understand what you are actually solving for. This is not just theory; it is a practice you can apply in your next team meeting. The best AI prompts, the smartest automation, and the fastest deployments are worthless if we are solving the wrong problem. It is time to stop optimizing for speed and start optimizing for understanding.

Data Sovereignty Is Built, Not Bought

  • Developer Experience
  • Policy & Compliance

For two decades, hyperscalers have claimed that using modern cloud services requires moving all your data into their datacenters, subjecting it to foreign jurisdictions like the US CLOUD Act. This talk challenges that assumption. We show how cloud-native technologies enable managed cloud services to be delivered where the data already lives: on-premises, in a private cloud, or with trusted public providers. Using Kubernetes and CNCF projects such as Crossplane, Prometheus, and Grafana, we present a platform model where databases, queues, caches, and DevOps tools are delivered as self-service managed services without data relocation or provider lock-in. Data sovereignty, we argue, is not a contract; it’s an architectural decision.

Hard-won lessons after processing 6.7T events through PostgreSQL queues

Aris Tzoumas

  • 30min Talk
  • Platform Engineering
  • AI, ML & Big Data
  • Cloud Native 101

Many organizations reach for specialized streaming systems like Apache Kafka for high-throughput event processing. But is it always the best choice? What if you choose PostgreSQL instead. This talk chronicles six years of battle-tested lessons learned while scaling PostgreSQL from a simple queue to a system processing 100,000 events per second, and delivering total 6.7T events. Learn about the specific configuration values, query patterns, and architectural decisions that enabled PostgreSQL to compete with and often outperform dedicated messaging systems, while providing the operational simplicity and transactional guarantees that only PostgreSQL can offer.

Silicon Cortex: Building an Autonomous AI Engineering Team Inspired by a Thermal Printer

Abhimanyu Selvan

  • 30min Talk
  • Kubernetes & Container
  • Developer Experience

We set out to build an autonomous AI software engineering team. Describe what you want, machines build and ship it. Agents take natural language tasks, write production code, push to GitHub, deploy to cloud. No human intervention. But orchestrating AI agents is hard. They're bursty, ephemeral, unpredictable. Idle for hours, then dozens spin up at once. A task takes five minutes, then the agent should vanish. You can't pre-provision for demand you can't forecast. We reached for the standard playbook. Kubernetes Deployments. HPA for scaling. PostgreSQL task queues. Polling loops. Then we looked up from the laptop. The thermal printer was printing a label. Inkjet printers have cartridges that dry out when idle. Thermal printers have no ink. Just heat and paper. No waste when not printing. We had built an "inkjet architecture" for a "thermal workload". Always-on Deployments polling for work. Paying for pods that were waiting. Ink drying in the cartridge. We rebuilt on thermal principles using Knative Eventing. CloudEvents flow through a Broker. Agent pods spawn as Kubernetes Jobs when events arrive, then terminate. One task, one Job. Zero tasks, zero pods. Services emit events, Triggers route them, nobody knows about anybody else. NGINX at the edge. Redis for state. Knative as the nervous system. Claude Code writes the software. The demo: submit a task, watch the event flow, see the AI write code, push to GitHub, deploy to cloud. Then the thermal printer prints a receipt. Physical proof that software wrote software. The machine that taught us how to architect now validates what we've built.

Building the Next Generation of Checkpoint/Restore in the Open

Adrian Reber

  • 30min Talk
  • Kubernetes & Container
  • OS & Cloud Native Infrastructure
  • Operations & Performance

Since 2022, Kubernetes has supported checkpointing and restoring individual containers. While that initial work demonstrated the capability, it also revealed a demand for a clearer roadmap and a more open design process regarding future developments. We are now taking the next big step: bringing these capabilities to Pods. As Pods are the atomic unit of Kubernetes, this shift is essential for handling attached resources correctly. To make this happen, we created the Kubernetes Checkpoint Restore Working Group. We want to build this feature in the open, bringing the community together to ensure the solution works for everyone.

Zoom in and you shall find: Adaptive Kubernetes SOC that stays sovereign and reduces data volume

Constanze Roedig

  • 45min Deep Dive
  • Network & Security
  • Operations & Performance

The linux kernel through eBPF offers to unify the disparate fields security and observability through shared data structures. We show how a K8s Security Operations Center, organically composed of established eBPF projects can see signals that the individuals cannot. We explain how we achieve both a comprehensive baseline and use independent signals to dial up/down coverage as suspicious indicators surface. The mutual independence of signals from across processes, file system, and network activity achieves a high signal-to-noise, enabling manageable data volumes and facilitating selective forensic storage. You will see two shorts demos: (A) of a root-kit which is hard to detect for sys-call based security tools in their default configurations, however almost trivial to detect with our adaptive setup. (B) of an agentic AI attack that mimicks a cobalt-strike C2 server You ll also learn how our SOC architecture is node-local and can be airgapped. This means no data leaves the cluster and you remain sovereign and in control of your data.

No More Forks: Policy Transformation for Terraform at Scale

Anton Babenko

  • 45min Deep Dive
  • OS & Cloud Native Infrastructure
  • Policy & Compliance

Every org enforcing Terraform standards eventually hits the same wall: policy tools can flag issues, but they cannot fix module code. The result is a graveyard of forked modules that drift from upstream and turn upgrades into a full-time job. This talk introduces policy transformation: automatically rewriting Terraform modules at download time so teams get compliant code without maintaining forks. I will demo eight real transformation rules across four categories: lifecycle management (prevent_destroy, ignore tag drift, protect KMS keys), block removal (strip provisioners), attribute restriction (deny GPU or specialty instances), and content sanitization (safe regex cleanups). You will see the before-and-after HCL, plus the safety model that makes this production-ready: deterministic outputs, collision detection, preview diffs, and a four-level risk classification. You will leave with a practical decision framework for validate vs transform, a DIY toolkit using pre-commit, hclwrite, custom tflint rules, and plan validation, and a simple migration path from module forks to rule-based enforcement. No vendor account required to apply the patterns from this talk.

CRAcking Compliance - The EU Cyber Resilience Act

Christian Schabetsberger

  • 45min Deep Dive
  • Network & Security
  • Policy & Compliance

The Cyber Resilience Act (CRA) will be arriving in the European Union in 2027, and with it a lot of new obligations. What we already consider good practices in our software industry today will be required by law tomorrow. In this talk, we will take a look at what's inside the CRA, who will be affected by it, and what new requirements we will have to fulfil. After that, we will take a look at tooling to generate Software Bills of Materials (SBOMs) for our .NET and JavaScript projects, as well as how to visualise and integrate them into existing CI workflows. Last but not least, we will take a look at how to handle the required vulnerability management with (semi-)automated dependency updates by utilising tools like Dependabot or Renovate and how to reduce dependencies with distroless images.

Beyond API Keys: Fine-Grained AI Agent Authorization for DevOps with OpenFGA

Tom Graupner

  • 45min Deep Dive
  • Platform Engineering
  • AI, ML & Big Data

AI agents are becoming first-class actors in DevOps platforms. They open pull requests, trigger CI/CD pipelines, scale Kubernetes workloads, and respond to incidents and, all of this increasingly without a human in the loop. Yet most organizations still authorize these agents with static API keys, personal access tokens, and broadly scoped CI secrets. This creates a dangerous gap. Tokens prove identity, but they don't answer the question that actually matters: *Should this agent perform this action, for this user, on this resource, in this environment, right now?* In this talk, I'll break down why token-based authorization fails for agentic DevOps (over-privileged bots, context-blind decisions, and zero auditability) and introduce a practical architecture that closes the gap: an **Agent Gateway** backed by **OpenFGA**, an open-source Relationship-Based Access Control (ReBAC) engine. You'll see a **live demo running inside Kubernetes** that walks through real scenarios: - **GitOps governance:** Contributors can open PRs; only maintainers can merge to main. - **Deployment promotion:** Staging deploys move fast; production requires explicit human approval. - **Agent trust boundaries:** Approved bots act; unknown bots are denied —> no implicit trust. Every action flows through the gateway: **AI Agent → Agent Gateway → OpenFGA → downstream system**. Authorization decisions are relationship-based, computed at runtime, and fully auditable. You'll walk away with a concrete, reusable pattern (authorization model, trust tuples, gateway design) that you can adopt in your own platform. No vendor lock-in. No custom policy DSL. Just declarative relationships and an open-source engine that treats authorization as a control plane, not an afterthought.
