In Kubernetes, TLS certificates are typically stored in Secrets and mounted into pods. When a Secret is updated, for example, due to certificate rotation by cert-manager, Kubernetes updates the projected secret volume. Hot reload mechanisms detect these file changes and reload TLS certificates without restarting the pod. This enables live certificate rotation, maximizes availability, and reduces operational risk associated with restarts. The approach makes shorter-lived TLS certificates operationally viable. Janne is a Cloud Platform Engineer at the SIX Group, where he builds cloud platforms and services for the financial community. Originally from Finland, he now lives in Baar, Zug. Opinions are his own. Cloud-Native Application Definition and Delivery with OAM and KubeVela, Raffael Klingler (AXA) What if developers could focus on their applications instead of the platform beneath them? The Open Application Model (OAM) makes this possible by shifting the focus from containers and orchestrators to applications themselves. Instead of wrangling low-level Kubernetes manifests, developers define applications using modular, reusable building blocks. KubeVela brings this model to life, rendering abstract definitions into deployable resources. In this session, we'll explore how OAM enables application-centric definitions and see KubeVela in action. You'll see an application evolve from a simple definition to a sophisticated setup with cloud-managed services and GitOps integration. Raffael Klingler is a Platform Engineer at AXA Switzerland, where he helps development teams ship software faster and more reliably. He recently completed his Master's thesis on Internal Developer Platforms, diving deep into OAM, KubeVela, and the challenge of making application delivery less painful. When not wrangling Kubernetes manifests, he's probably thinking about how to make developers' lives easier. From Problem to Production: DevOps for AI with Kubeflow, Fabrizio Lazzaretti (Wavestone) and Marco Crisafulli (enki) Despite massive investments in AI, most enterprise AI initiatives fail to reach production — not because of model quality, but because of fragmentation among data science, platform engineering, and business teams. MLOps addresses this challenge by applying DevOps principles to machine learning, and Kubeflow has emerged as a de facto open platform for operationalizing these practices in cloud-native environments. In this talk, we explore how Kubeflow enables collaboration, automation, and repeatability across the entire ML lifecycle, from requirements gathering and experimentation to deployment and continuous improvement. Using a real end-to-end example, we’ll demonstrate how Kubeflow Pipelines, training workflows, and integration with the CNCF ecosystem help teams move beyond ad-hoc experimentation toward production-grade AI systems. Attendees will see how a vendor-neutral Kubeflow-based MLOps architecture supports multi-cloud deployments, enforces operational best practices, and creates continuous feedback loops between stakeholders. Whether you are introducing MLOps for the first time or refining an existing platform, this session provides practical insights into using Kubeflow to turn AI from a research activity into a sustainable business capability. Fabrizio Lazzaretti is a Managing Consultant at Wavestone and CNCF Ambassador who bridges cutting-edge cloud-native technologies with enterprise architecture. As maintainer of the CloudEvents Rust SDK and co-author of "Crafting Great APIs with Domain-Driven Design," he brings deep expertise in event-driven architecture and microservices to complex challenges. With over 10 years of experience in software architecture, development, and DevOps, he currently drives architectural transformation and AI initiatives across sectors, connecting business and IT through collaborative API design. Marco Crisafulli is the co-founder of enki, a Swiss machine learning company focused on training, consulting, and implementing practical ML use cases for Swiss enterprises. With a strong background in enterprise software and cloud-native infrastructure, he specializes in MLOps, Kubernetes, and production-grade ML platforms, and has deep hands-on experience with Kubeflow. He works closely with organizations to bridge the gap between experimentation and reliable ML systems in production, helping teams operationalize ML at scale. Bye-bye Ingress-NGINX, hello Gateway API The Kubernetes ecosystem is undergoing a major transformation as the legacy Ingress model, long dominated by the NGINX Ingress Controller, reaches its limits and faces discontinuation. This talk explores why the Kubernetes Gateway API is emerging as the new standard for security and architecture. We'll dive into the shortcomings of traditional Ingress (including "annotation hell" and recent security vulnerabilities) and highlight the architectural and operational advantages of Gateway API. Finally, we will present a few options on how you can move forward and implement a new solution. Urs Zurbuchen is a Senior Security Consultant at Airlock. As an engineer and consultant for the design and implementation of IT security solutions, he is familiar with the requirements for secure digitalisation processes. Urs has more than 20 years of experience in designing and integrating web application security solutions (web application firewall, authentication, single sign-on, access control) as well as in designing and implementing identity & access management projects (user management, authorisation management, processes, provisioning). Mr Zurbuchen can advise on the conception of non-technical topics such as organisation, guidelines, compliance requirements and regulations, as well as on the implementation of application and system architecture audits.

After a long hiatus of the compiler social, Lorenzo is joining us to talk about the exciting work happening at NVIDIA that you have probably heard about, namely cuTile/TileIR. As usual there will be pizza, snacks, beer, and soft drinks after the event for participants, sponsored by NVIDIA. **Astract:** GPU programming has evolved significantly over the past decade, driven by rapid hardware innovation such as Tensor Cores and new numerical formats. However, the gap between high-level productivity frameworks and low-level performance-centric programming models continues to widen. In this talk, we introduce cuTile and TileIR, a new block-level programming model and intermediate representation designed to simplify high-performance GPU development while preserving forward compatibility with evolving NVIDIA architectures. cuTile provides a tile-centric abstraction for data-parallel workloads, accessible from Python, while TileIR—an MLIR-based low-level IR integrated with CUDA—offers a stable, portable foundation for targeting tensor cores and future hardware generations. Together, they establish a middle ground between usability and control, enabling expressive kernel development without sacrificing performance. We present the programming model, illustrate it with examples, discuss performance considerations, and, if time permits, take a deeper dive into the core abstractions behind TileIR: https://github.com/NVIDIA/cuda-tile **Location:** The event is taking place in the room G59 in the CAB building of ETH Zurich at the Zentrum campus. Enter from Universitätstrasse 6.

When you sign up, please let us know whether you’ll attend in person or online. **Schedule** **18:00 – 18:30** Welcome & Networking **18:30 – 19:00** **GraphQL Batching: DataLoaders and Batch Resolvers Explained** \- Michael Staib GraphQL servers rely on batching to avoid the N+1 problem, but where should batching actually happen? In this talk, we explore three common approaches: DataLoaders, Batch Resolvers, and breadth-first (BFS) execution. While all aim to reduce redundant data fetching, they solve different problems and live at different layers of your stack. We will examine how each approach works, when to use one over the other, and how modern GraphQL servers implement batching under the hood. Along the way, we will look at practical execution details like field merging and batching across multiple operations. By the end, you will have a clear mental model for GraphQL batching and the trade-offs between DataLoaders, Batch Resolvers, and BFS execution. **19:00 – 19:30** **Semantic Introspection** \- Pascal Senn GraphQL's rich type system makes it an ideal foundation for agents to explore and work with APIs. The SDL provides the structure agents need to reason about capabilities and data. Queries let them retrieve information, while mutations enable them to take action. In practice, however, production GraphQL schemas are often too large to fit in the context window and difficult to understand without additional context. So what if agents could interact with any GraphQL API in a generic, reliable way? In this session, we'll look at the challenges of agentic interactions with GraphQL and how semantic introspection could unlock a new way for agents to navigate the schema and interact with GraphQL APIs more reliably. **19:30 – 20:00** **The Future of GraphQL Federation: Composite Schemas in action** \- Tobias Tengler GraphQL federation enables teams to compose multiple services into a single unified API. But the federation ecosystem is evolving. In this talk, we introduce the GraphQL Composite Schema specification, a new open standard developed under the GraphQL Foundation and co-created by Apollo, The Guild, and ChilliCream. Rather than introducing yet another competing approach, the Composite Schemas specification aims to standardize and modernize GraphQL federation by addressing limitations of earlier federation protocols. We will explore how GraphQL APIs can be federated using Composite Schemas and how queries are planned and executed across services. Along the way, we will demonstrate the first implementation of the specification with Hot Chocolate Fusion 16 and share some of the design decisions behind it. By the end, you will understand what Composite Schemas are, how they improve GraphQL federation, and how to start using them with Fusion.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
