Our hero, a running app in a K8s prod environment, knows they are destined for greater things! They’re serving end users, but the value of the cloud is not realized. Hero’s devs toil on custom integrations, deployment is brittle and slow, and security and governance are HARD. Hero longs for a developer platform with consistent and repeatable system building blocks.
It is up to you, the audience, to guide our hero’s transformation from a lost and confused app to one built on a solid foundation that abstracts away complexity and promotes innovation. In their fifth KubeCon ‘Choose Your Own Adventure’-style talk, Whitney and Viktor will present choices that an anthropomorphized app must make as they build an Internal Developer Platform, enabling the devs to have self-service access to widely used system capabilities. Throughout the presentation, the audience (YOU!) will vote to decide our hero's path! Can we navigate CNCF projects and build a platform before the session time elapses?

Cold-start delays for GPU-heavy GenAI apps like ComfyUI aren’t just about speed—they’re architectural failures. While others optimize incremental steps, we eliminate entire phases: no image downloads, no layer extraction, no redundant model copies.
We introduce a radical Kubernetes-native pattern: Direct-to-GPU streaming via FUSE-mounted object storage (S3/GCS), bypassing legacy container workflows. By rearchitecting the snapshotter to support seekable, on-demand FUSE streaming, we enable:
- Instant container boot: Models/CUDA dependencies mount directly from object storage, avoiding registry bottlenecks (40MB/s → 900MB/s throughput) - Zero-extraction overhead: Layers load incrementally via range-optimized fetches, eliminating Zstd unpack/copy latency - True cold start elimination: ComfyUI pods activate in 90s (vs. 8+ mins) by co-locating model mounting and inference prep
We’ll dissect a live ComfyUI deployment using 100% OSS primitives to hack container internals in the session.

Kubernetes is widely recognized as a platform for building platforms, but even with modern platform engineering techniques, managing an end-to-end release and deployment lifecycle remains challenging.
This talk will first analyze key pain points in platform engineering and propose a new perspective on infrastructure code by separating different personas’ views. We advocate for a tenant-centric API that prioritizes user experience—minimizing input, reducing learning curves, and abstracting cloud provider details to decouple desired resources from underlying specs.
Next, we’ll introduce a design for fanning out tenant resource claims, enhancing flexibility and extensibility through a code generation component and a Kubernetes-like labeling system. Finally, we’ll cover the glue that binds everything together: Pkl for templating and validation, Prow for GitHub event-driven automation, and Crossplane + ArgoCD as the claim realization engine.

As organizations scale their Kubernetes adoption, multi-cluster architectures are becoming the backbone of resilience, scalability, and compliance. However, building a unified developer experience across these clusters while abstracting operational complexities is a significant challenge. In this session we’ll demonstrate how Cluster-API (CAPI), a declarative tool for Kubernetes lifecycle management and Linkerd, the powerful yet lightweight service mesh, can work together to simplify multi-cluster topologies for Internal Developer Platforms (IDP). By combining CAPI's robust cluster management with Linkerd’s seamless cross-cluster service communication, platform teams can deliver a streamlined and intuitive experience for developers, enabling them to focus on building and deploying applications without worrying about underlying infrastructure.

You probably have more than one cluster and there is a decent chance you are using Argo CD. Additionally, it is quite likely that you have a few other variations of Kubernetes cluster lists. We posit that writing glue code to stitch together these clusters lists is not an awesome use of your time. Thankfully the good folks in SIG-Multicluster built this super cool api for cluster lists, cluster profile/cluster inventory! We are going to show you how to use said fancy new list with Argo CD along with other multi-cluster tools across Kubernetes clusters hosted by different providers. There will be demos. Possibly Mustaches. And a decent amount of awful puns. So come on down to bear witness to some sweet multi-cluster abstractions that will surely get your heart rate up.

Platform Engineering enables developers to focus on business value-aligned tasks by providing internal developer platforms (IDPs) that automate non-essential tasks. Kubernetes is widely used as a foundation for IDPs thanks to its scalability and flexibility.
However, Kubernetes was designed as a general workload orchestrator, not a platform component. As a result, IDP builders must integrate additional Cloud Native technologies and customizations, which can create scalability bottlenecks. At LY Corporation, his team has developed a Kubernetes-based, multi-tenant IDP running over 140K pods, and they faced such scalability challenges.
In this session, he will discuss scalability bottlenecks faced in the IDP, including observability pipelines, access control, etc. He will also explore scaling strategies for IDPs and how they address real-world scalability issues. By the end of this session, you will gain deeper insights into scalability challenges from a platform builder’s perspective.

How can real-time event streaming platforms, handling millions of events and complex data processing, maintain peak performance and reliability? Managing the same has previously been complex. The latest agent changes and addition of semantic convention in OpenTelemetry make it ideal to monitor highly distributed event streaming architectures (EDA) like Kafka. In this session we will discuss how these changes help standardize telemetry, explain the usage of span links for capturing several traces for a transaction in EDA.
The talk will also cover how Otel enables automatic anomaly detection particularly useful for identifying issues like Consumer Lag, Increased Latency in Event Processing, and Partition Failures. By leveraging context propagation, Otel tracks end-to-end latency across the entire Kafka ecosystem, including producers, brokers, and consumers.
The talk covers real-world examples from gaming platforms and data systems which have enabled Otel for Kafka monitoring.

OpenTelemetry has become the go-to framework for unifying observability signals across metrics, logs, and traces. However, implementing OpenTelemetry often comes with its own set of challenges: broken instrumentation, missing signals, and misaligned semantic conventions that undermine its effectiveness. Debugging these issues can be daunting, leaving teams stuck with incomplete or unreliable observability data.
In this session, Kasper will demystify the debugging process for OpenTelemetry. Attendees will learn how to identify and troubleshoot common issues, ensure signals are transferred correctly, and align instrumentation with semantic conventions for consistent insights.

In this session, the speaker presents TopoLVM, a CSI plugin for local storage, and introduces an upcoming Kubernetes feature for local storage that he and his team are working on.
Local storage is promising for applications that require high I/O performance, like Elasticsearch and MySQL. TopoLVM provides many features like raw block volumes, resizing, and dynamic provisioning to manage local storage in Kubernetes easily. It also includes a capacity-aware pod scheduling feature that considers each node's local storage capacity.
Currently, this capacity-aware feature is achieved by a scheduler extender, which has two main issues:
1. Many admins don't have the right to install scheduler extenders. 2. The scheduler extender is TopoLVM specific.
To address these issues, he will introduce a KEP titled "KEP-4049: Storage Capacity Scoring of Nodes for Dynamic Provisioning." to be able to TopoLVM's scheduling logic for all CSI drivers without using scheduler extenders.
