Keynote: Platform Alchemy: Transforming Kubernetes Into Generative AI Gold - Alexa Griffith, Bloomberg & Mauricio "Salaboy" Salatino, Diagrid
Monday June 16, 2025 09:54 - 10:04 JST
Level 1 | Pegasus A-B1
As Generative AI reshapes the tech landscape, its tools and solutions often feel overwhelming and disconnected - like scattered elements waiting to be forged into something greater. What does a complete GenAI platform look like? And how does it differ from application-focused platforms many organizations already run?

We’ll guide you through a practical transmutation of your platforms to add GenAI features. We’ll first define the base elements needed to deploy LLM inference on Kubernetes. We’ll then blend key elements into the MVP stage, adding core enterprise AI components like an AI Gateway, shared interfaces via Dapr, and KServe-based deployment strategies. Finally, we’ll tackle advanced features - intelligent load balancing for LLMs, observability patterns, and cost optimizations.

More than a tools showcase, this session is packed with real lessons from enterprise GenAI platform engineers, to help transmute your platform into the philosopher’s stone for AI innovation.

Keynote: Service Mesh is Evolving into the Service Network - Lin Sun, Head of Open Source, Solo.io
Monday June 16, 2025 10:06 - 10:11 JST
Level 1 | Pegasus A-B1
Traditional service meshes often rely on sidecars, which can introduce added complexity and require application restarts. But things are changing. Modern service mesh is evolving into what we now call a service network—where the mesh dissolves into the infrastructure itself, becoming part of the infrastructure.

In this live demo, Lin will showcase how today's service mesh can be completely transparent to applications. She'll demonstrate how you can use gateways to implement Layer 7 traffic management and security policy enforcement, all while running her AI application that engages with and analyzes the audience's mood.

Keynote: From ECS To Kubernetes (and Sometimes Back Again): A Pragmatist's Guide To Migration - Marc Hildenbrand, Canva
Monday June 16, 2025 10:13 - 10:23 JST
Level 1 | Pegasus A-B1
Migrating to Kubernetes offers numerous benefits, but few organizations start from "greenfields" circumstances. Many have critical services running on existing platforms, each leveraging unique capabilities. Transitioning these services to Kubernetes can be a complex and non-trivial challenge.

At Canva—a leading design and collaboration platform serving 220 million monthly active users—we recently undertook an ambitious project to migrate over 400 services from Amazon Elastic Container Service (ECS) to Kubernetes (EKS). These services now span 15,000 pods across two clusters on a typical day.

In this talk, we’ll share the strategies, tools, and processes Canva developed to achieve a (mostly) seamless migration with minimal disruption to our teams and users. Whether you're planning your own migration or just curious about what it takes to migrate at this scale, this session will provide practical insights and lessons learned.

Sponsored Keynote: Challenging to the Innovative Infrastructure for the AI Revolution - Yuichi Saotome, VP, Platform BG Executive Director, Fujitsu Limited
Monday June 16, 2025 10:25 - 10:30 JST
Level 1 | Pegasus A-B1
Generative AI's rise demands massive compute resources and energy, conflicting with the urgent need for sustainability.

Composable Disaggregated Infrastructure (CDI) offers a solution by disaggregating servers into modular components connected via PCIe/CXL, enabling software-defined "composed server".

To address the growing resource demands of AI, particularly GPU utilization, Fujitsu is challenging the open-sourcing of a Kubernetes (K8s) mechanism for orchestrating CDI, under the CNCF community." This promotes vendor-neutral standardization, crucial for next-gen data centers handling explosive AI workload growth.

We aim to establish this as an open standard within CNCF/CNCJ, encouraging broad participation. Looking ahead, Fujitsu is developing "Optical Disaggregated Computing" for high-speed, low-power infrastructure in the 2030s.

Leveraging our CDI-based cloud technologies and photonics technologies, it delivers cloud-to-edge computing, improving efficiency, reducing power, and enabling low-latency.

Beyond K8s, Fujitsu's OSS contributions span AI, edge, and networking. We've strengthened our organization to focus on Linux/K8s and are committed to collaborating within the LF/CNCF ecosystem.

Keynote: Cloud Native Darwinism: Continuous Evolution of Platforms for Competitive Edge - Masaya Aoyama, Senior Software Engineer, CyberAgent
Monday June 16, 2025 10:32 - 10:42 JST
Level 1 | Pegasus A-B1
In the rapidly evolving world of cloud native technologies, new projects and paradigms are constantly emerging. To keep up with this momentum, platforms built on Kubernetes and cloud native ecosystem must continuously evolve as well. Choosing technologies and architectures is no longer a one-time decision—it requires continuous reevaluation and adaptability. By embracing flexibility and continuously adopting better solutions as they become available, end-users can maintain the competitive edge. This session will highlight the importance of continuously evolving platforms within the open-source ecosystem and introduce the powerful extensibility of Kubernetes that enables such evolution. Attendees will gain insights into how to keep competitive through continuous evolution, and we'll explore the next actions of early adopters and the trends in the upstream Just as the sun continues to rise in the Land of the Rising Sun, the evolution of your platform will illuminate the path to a brighter future for you, your company and your country.

A Journey and Lessons Learned To Enable IBM AIU Accelerators in Kubernetes - Takuya Mishina & Tatsuhiro Chiba, IBM Research
Monday June 16, 2025 11:30 - 12:00 JST
Level 1 | Pegasus A-B1
In this presentation, we will unveil the secrets and journey to enable an IBM's AI Accelerator in Kubernetes. We utilize wide range of tools and frameworks such as device plugin, custom scheduler, metrics exporter, webhooks and custom resources together to satisfy real requirements from various stakeholders - general users, cluster administrators and driver/runtime developers. Our device plugin and custom scheduler can accept special preference such as topology-aware allocation to enable RDMA, and webhook-based validator guides them to follow specification changes. To sync up allocation status among the components, we carefully defined a custom resource after performance estimation. From developer perspective, we provide various debug-purpose capabilities: for example, device allocation by PCI address for inspection, and pseudo device mode to achieve non-real-device test. In addition, multi-architecture support gives freedom of platform choice to all of the participants.

Choose Your Own Adventure: The Dignified Pursuit of a Developer Platform - Whitney Lee, Datadog & Viktor Farcic, Upbound
Monday June 16, 2025 11:30 - 12:00 JST
Level 1 | Orion
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?

Never Underestimate Memory Architecture - Bryan Boreham, Grafana Labs
Monday June 16, 2025 11:30 - 12:00 JST
Level 1 | Pegasus B2-C
Modern cloud servers are built on NUMA (Non-Uniform Memory Access) and SMT (Symmetric Multi-Threading, aka Hyperthreading) — but few engineers realize how much these technologies impact application performance.

NUMA means that your cloud server’s memory might be significantly slower to access, because it’s connected to a different CPU, while Hyperthreading makes a single CPU core pretend to be two, but not at twice the speed.

This talk will:
• Demystify NUMA & Hyperthreading — what they are, how they work, and why they matter.
• Explore Kubernetes integration—the (limited) ways Kubernetes interacts with NUMA.
• Show real-world performance impact — illustrated with measurements on AWS and Google Cloud.
• Give you visibility — how to use Prometheus metrics and Linux commands to view your servers’ NUMA and SMT configurations.

By the end of the session, you'll have an understanding of the issues, and the tools to measure and their impact on the performance of your workloads.

Beyond Stock Outs: Scaling Inference on Mixed GPU Hardware With DRA - John Belamaric & Bo Fu, Google
Monday June 16, 2025 12:10 - 12:40 JST
Level 1 | Pegasus A-B1
Pods are PENDING?!? Ugh, none of the latest GPUs are available. But there are tons of older ones! If only you could tell Kubernetes “use the best GPU available, as long as it has 20GB+”...(enter: DRA).

Kubernetes’ Dynamic Resource Allocation (DRA) system, beta since 1.32, allows variations on which GPUs get allocated to Pods. You can write a flexible spec so that when the Deployment scales, Pods can land on whatever nodes have available GPUs. DRA works even if you need different numbers of devices for different hardware! This enables a new level of utilization and efficiency, saving your organization real money.

Combined with an advanced Node Autoscaler like Google’s Custom Compute Classes or Karpenter, you can spin up more VMs with whatever GPUs are available - or the most economical - all for a single Deployment. Scaling is simpler and more reliable, and your workload can scale even when your preferred type of GPU is stocked out.

Come learn how, and see it in action with a demo!

New Cache Hierarchy for Container Images and OCI Artifact in Kubernetes Clusters Using Containerd - Toru Komatsu & Hidehito Yabuuchi, Preferred Networks, Inc.
Monday June 16, 2025 12:10 - 12:40 JST
Level 1 | Pegasus B2-C
One of the key bottlenecks in Kubernetes pod startup is the time taken to pull container images and OCI artifacts. It’s also costly to fetch large container images from the registry often. To tackle this problem, we developed a cache system with the following features:

* New Cache Hierarchy: Images pulled by pods are shared across the entire cluster, enabling cluster-wide optimization, not only cluster-local cache.
* Ninja: Users experience faster container image pulls without any changes on their part. Just like a ninja, the system stealthily enhances performance.
* Preheating: It supports pushing images to preheat the cache for subsequent pulls.

Deployed in a production cluster, the cache system has achieved a cache hit rate of around 95%, significantly reducing pod startup times and network communication with registries. Attendees will learn practical insights into leveraging cache and CRI to optimize image and OCI artifact pulls, ultimately enhancing cluster efficiency.

⚡ Lightning Talk: Embracing Culture and Breaking Language Barriers: A Story of Fostering Global Opensource Communities - Sreeram Venkitesh, DigitalOcean
Monday June 16, 2025 14:10 - 14:15 JST
Level 1 | Pegasus A-B1
Open source communities are a celebration of our different cultures. The single reason open source communities are able to build and ship software like Kubernetes, which is used so widely, is because of the collaboration of people from all around the globe.

This also means a lot of challenges when people are working together, like language barriers, cultural differences and timezones. In this talk I'll be sharing some lessons I've learnt about fostering open source communities amidst the differences. In the last two years, serving in the K8s release team and as the SIG Docs New Contributor Ambassador, I've experienced first hand how challenges like language barriers can hinder enthusiastic contributors. This talk is about these different challenges and how we can overcome them.

In an effort to inspire everyone in the open source community to embrace our differences and welcome everyone as we work together, I'm learning Nihongo to attempt giving this talk in the Japanese language.

⚡ Lightning Talk: Enhanced Service Redirection: eBPF Ensures the High Availability of Node-Local DNS - Weizhou Lan, Daocloud
Monday June 16, 2025 14:17 - 14:22 JST
Level 1 | Pegasus A-B1
Excessive DNS query pressure can cause CoreDNS failures, leading to a cluster-wide meltdown. Thus, per-pod or per-node DNS proxy is a common high-availability solution. By binding the clusterIP of the kube-dns service to the local node, node-local DNS can provide seamless DNS interception and proxying, meeting the demands of low latency and high throughput. However, proxy's breakdown can directly lead to access failures, lacking high availability.
To solve this issue, we use cgroup eBPF to implement enhanced service redirection for node-local DNS, inspired by Cilium's LocalRedirectPolicy. Based on the health status of the local proxy or the redirection QoS strategy, the query of the kube-dns service can be dynamically resolved to the local node-local DNS, otherwise normally forwarded to CoreDNS. This scheme is independent of the CNI, and could cooperate with kube-proxy, offer multiple service redirection strategies and provide production-grade quality assurance for node-local DNS.

⚡ Lightning Talk: From Kernel To Kubernetes: Mapping eBPF-Detected Processes To Pods - Yuki Nakamura, mapbox
Monday June 16, 2025 14:24 - 14:29 JST
Level 1 | Pegasus A-B1
When a process like /usr/bin/curl runs in a pod (e.g., xwing in the default namespace), Tetragon detects it like bellow:

```
🚀 process default/xwing /bin/bash -c "curl https://ebpf.io/applications/#tetragon"
🚀 process default/xwing /usr/bin/curl https://ebpf.io/applications/#tetragon
💥 exit default/xwing /usr/bin/curl https://ebpf.io/applications/#tetragon 60
```

But how does it map that process to its pod?

This Lightning Talk explores how Tetragon connects the Linux kernel to Kubernetes by enriching eBPF-detected process data with Kubernetes metadata. I’ll break down how it extracts cgroup information from task_struct in kernel space and maps it to pod details using the Kubernetes API.

⚡ Lightning Talk: Practical Monitoring for Knative Serving - Kazuki Higashiguchi, Autify
Monday June 16, 2025 14:38 - 14:43 JST
Level 1 | Pegasus A-B1
Knative is a widely adopted CNCF-hosted software for running serverless applications using Kubernetes. Knative Serving consists of many system components, such as Activator, Autoscaler, Controller, Webhook, and Istio or Kourier as an ingress gateway. Therefore, end users need to implement monitors for common error patterns and best metrics from many metrics. However, there is relatively little knowledge and resources for Knative end users.

This talk will present a production case study of monitoring for Knative Service. Specifically, it will explain how we can monitor Knative control plane efficiency, reconciliation operations, pod scaling health, concurrency observation, HTTP request success rate, and more.
That includes how Knative components implement Prometheus metrics, metrics pipelines (on Google Kubernetes Engine), dashboards and alerts.

This case study will benefit existing Knative users and potential users considering employing Knative in their Kubernetes clusters.

⚡ Lightning Talk: Providing Sufficient PVCs for Your StatefulSets: Creating New Volumes Larger Than the PVCTemplate - Kaoru Esashika, Cybozu, Inc.
Monday June 16, 2025 14:45 - 14:50 JST
Level 1 | Pegasus A-B1
Have you ever used automatic PVC resizing tools in Kubernetes? Have you ever encountered a situation where newly created PVCs remained at the small, template-defined size, causing capacity shortages during restores or clones?

To address this challenge, this session introduces a new approach in pvc-autoresizer, one of the tools for automatically resizing PVCs. By aligning newly created PVCs with the largest capacity in the same group, it ensures that PVCs have sufficient space right from creation time. Using annotations and a Mutating Webhook, we avoid capacity shortages during restores by provisioning enough volume capacity immediately after a PVC is generated. We will also explain why we chose a Webhook-based method over a Controller-based one, along with the design trade-offs involved.

Anyone seeking to enhance reliability for stateful workloads should not miss this session. Learn how a new PVC management strategy can deliver more stable Kubernetes storage.

Zero-Extraction Cold Starts: How FUSE-Streaming Slashed ComfyUI Cold Starts by 10x - Fog Dong, BentoML
Monday June 16, 2025 14:50 - 15:20 JST
Level 1 | Orion
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.

⚡ Lightning Talk: VexLLM: Silence Negligible CVE Alerts Using LLM - Akihiro Suda, NTT
Monday June 16, 2025 14:59 - 15:04 JST
Level 1 | Pegasus A-B1
When using container image vulnerability scanners like Trivy, a large number of vulnerabilities may be detected. However, not all of them necessarily require an action. This is because not all libraries or command-line tools included in the container image are actually utilized.

For example, the `python:3.12.4` image includes a `git` binary with the vulnerability CVE-2024-32002. This vulnerability does not need an immediate action if it is known that the Python application being run does not execute `git` commands.

VEX (Vulnerability-Exploitability eXchange) formats such as OpenVEX can be used to suppress such false alarms.
However, VEX is still not widely adopted due to the difficulty of manual analysis and classification of vulnerabilities.

This presentation introduces VexLLM, a tool that helps writing VEX by leveraging LLMs. VexLLM is available as a plugin for Trivy.

The Grand Adventure of Production Apps: Build, Break, and Survive! ~ A Kawaii Manga Journey Through - Aoi Takahashi, Independent
Monday June 16, 2025 15:50 - 16:20 JST
Level 1 | Pegasus B2-C
"I've started to understand the basics of Kubernetes, but when it comes to running it in production, I can't quite imagine what kind of issues might arise..."
To ease these concerns, this session will use original characters, illustrations, and animations in a “cute manga” style to visually demonstrate how production applications can break and how to troubleshoot them.
In our story, the main application as a character takes center stage as the hero, venturing out on a grand journey—only to be "suddenly attacked by a monster" at the most inopportune moment. By following this storyline, you will learn both how applications fail and how to fix them. Additionally, just as an adventurer equips better armor to prepare for future battles, we will explore common issues and explain how to prevent them from happening in the first place.
Join us on an exciting adventure in "manga-style troubleshooting" and gain the confidence to tackle production Kubernetes challenges head-on!

Optimizing Data Locality and GPU Utilization for Training Workloads in Kubernetes - Bin Fan, Alluxio
Monday June 16, 2025 16:30 - 17:00 JST
Level 1 | Pegasus A-B1
As organizations scale their model training workloads in cloud-native environments, they face significant data processing and storage challenges: managing massive training datasets across distributed storage systems while ensuring optimal I/O performance. While Kubernetes excels at compute orchestration, the increasing distribution of data across multiple storage backends creates bottlenecks that impact training performance and infrastructure costs.

This presentation introduces a Kubernetes-native distributed caching system that utilizes NVMe storage to overcome data locality challenges. Haoyuan Li will also share real-world, large-scale production use cases to show how this architecture lowers data infrastructure costs, increases GPU utilization, and enables workload portability to navigate GPU scarcity challenges.

Breaking Limits: Highly-Isolated and Low-Overhead Wasm Container - Soichiro Ueda, Kyoto University & Ai Nozaki, The University of Tokyo
Monday June 16, 2025 16:30 - 17:00 JST
Level 1 | Pegasus B2-C
Wasm is touted as the next generation of containers, offering a smaller, more secure, and more portable application format. However, challenges remain, particularly in achieving enough isolation for public clouds where multi-tenancy exists. This is because Wasm shares the host kernel between workloads like containers. To take full advantage of Wasm, there is still insufficient discussion on this problem.

To address the issue, we've developed a new Wasm runtime, Mewz. It runs a single Wasm module within a dedicated VM while also having a lightweight and specialized kernel (unikernel). This revolutionary execution model enables more secure and low-overhead Wasm containers. We've open-sourced the implementation, and Mewz is listed in the CNCF cloud native landscape! In this session, we'll explain the architecture of Mewz and why it's more isolated and low-overhead than ordinary Wasm runtimes. Building on this presentation, let’s discuss the future of cloud workloads powered by Wasm!

Exploring Tenant-centric Strategies To Simplify Multi-cluster and Multi-cloud Complexities - Wei Huang & Fan Yang, Apple
Monday June 16, 2025 16:30 - 17:00 JST
Level 1 | Orion
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.

2-Node Kubernetes: A Reliable and Compatible Solution - Xin Zhang & Guang Hu, Microsoft
Monday June 16, 2025 17:10 - 17:40 JST
Level 1 | Pegasus B2-C
High availability in Kubernetes typically requires a 3-node setup to support etcd's Raft algorithm. But what if you could achieve HA with only 2 nodes, slashing infrastructure costs by over 30% without sacrificing reliability? This is a game-changer, especially for deployments in retail and manufacturing scaling across hundreds or thousands of locations.
Join us to explore a groundbreaking 2-node HA Kubernetes solution, built by evolving the Raft algorithm for etcd. Unlike alternatives that compromise on compatibility, our approach delivers etcd-based HA, which can tolerate both node failures and network partitioning like a traditional 3-node cluster. You can seamlessly transit between 3-node and 2-node cluster utilizing standard tools like kubeadm or CAPI. This approach requires only a simple shared storage witness.
In this session, we will unpack the mechanics of this innovation, demonstrate 2-node cluster provisioning, and showcase its resilience under real-world failure scenarios.

Addons Need Love Too: Maintaining Addons for Better Cluster Security - Stevie Caldwell & Andy Suderman, Fairwinds
Monday June 16, 2025 17:10 - 17:40 JST
Level 1 | Pegasus A-B1
Projects both within and outside of the CNCF ecosystem provide additional capabilities for Kubernetes clusters. These "addons" become integral to the functioning of our clusters, but we don't often talk about their impact as a whole or managing them holistically as first-class citizens.

We know there are barriers to keeping things like addons up-to-date and that it can be difficult to get buy-in for allocating the time and resources for updating something that is working just fine (for now), especially if you’re multiple major versions behind. In this session we will help you understand and articulate the benefits of catching up and keeping addons updated and how to be proactive moving forward. You will walk away with some tools and strategies for navigating the complexity of the addon ecosystem and make the process as painless as possible. You will be able to create an action plan for improving the stability and security of your clusters and share that with stakeholders.
