Keynote: Platform Alchemy: Transforming Kubernetes Into Generative AI Gold - Alexa Griffith, Bloomberg & Mauricio "Salaboy" Salatino, Diagrid

Monday June 16, 2025 09:52 - 10:02 JST

Keynote Sessions, Platform Engineering

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: From ECS To Kubernetes (and Sometimes Back Again): A Pragmatist's Guide To Migration - Marc Hildenbrand, Canva

Monday June 16, 2025 10:11 - 10:21 JST

Keynote Sessions, Platform Engineering

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.

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

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, CNCF Ambassador & Viktor Farcic, Upbound

Monday June 16, 2025 11:30 - 12:00 JST

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

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, Google & Jack Francis, Microsoft

Monday June 16, 2025 12:10 - 12:40 JST

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

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: Enhanced Service Redirection: eBPF Ensures the High Availability of Node-Local DNS - Weizhou Lan, Daocloud

Monday June 16, 2025 14:17 - 14:22 JST

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

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

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

⚡ Lightning Talks, Data Processing + Storage

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

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

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.

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

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

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

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.

Monday June 16, 2025 17:10 - 17:40 JST

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.

Cloud Native Scalability for Internal Developer Platforms - Hiroshi Hayakawa, LY Corporation

Tuesday June 17, 2025 12:10 - 12:40 JST

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.

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.

How Green Is My OpenTelemetry Collector? - Adriana Villela, Dynatrace & Nancy Chauhan, Student

Tuesday June 17, 2025 14:50 - 15:20 JST

We live in a world heavily dependent on technology, and this comes at an environmental cost. For example, data centres consume 2% of global power. As our systems become more complex, power consumption will only increase. We strive to understand our systems through Observability, and yet making our systems observable contributes to an increasing global tech carbon footprint.

Luckily, tools like Kepler and Kube-Green help us understand our carbon footprint, and take mitigating actions. The Kepler Exporter exposes statistics, including power consumption metrics, from an application running in a Kubernetes (k8s) cluster. Kube-Green is an operator used to reduce the CO2 footprint of k8s clusters.

In this talk, attendees will learn about Kepler & Kube-Green, how to deploy them, and through a demo, how to apply them to deploy the OTel Collector to reduce power consumption and costs. Attendees will walk away with tools and knowledge to deploy greener Collectors and other k8s infrastructure.

Mastering Authorization: Integrating Authentication and Authorization Data in Cloud Native Apps - Yoshiyuki Tabata, Hitachi, Ltd.

Tuesday June 17, 2025 14:50 - 15:20 JST

Authorization is one of the most important considerations for cloud-native applications, as highlighted by the OWASP Top 10. For a long time, there was no clear standard, making authorization a significant challenge for many implementers. The OpenID Foundation AuthZEN WG is now working on standards, focusing on interfaces between PEP (Policy Enforcement Point) and PDP (Policy Decision Point), which provides some hope.
However, managing authorization data remains challenging. Since this data is closely related to authentication data, architects often struggle with how the OP (OpenID Provider) and PDP should manage and integrate it. There are multiple methods, and the best approach varies by use case.
In this session, Yoshiyuki Tabata will explain various methods for managing and integrating authentication and authorization data. He will also describe implementation using Keycloak for OP and Topaz for PDP, providing valuable insights into effective data management.

The Future of Prometheus Exposition Format - Arthur Sens, Grafana Labs

Tuesday June 17, 2025 15:50 - 16:20 JST

OpenMetrics (OM) had a wild journey: it started as a project to standardize the Prometheus exposition format, and it became an entirely separate CNCF Incubating project. Even though the project had high maturity, it struggled for years to find tools to comply with the first version of the spec. Finally, in 2025, it was incorporated back into the Prometheus Github organization so Prometheus developers could lead the efforts for OM 2.0.

In this talk, Arthur, a Prometheus maintainer and OpenMetrics contributor, will walk you through the main challenges that tools like Prometheus and OpenTelemetry face when trying to comply with OpenMetrics 1.0 and how the community plans to address these challenges in OM 2.0.

The audience will also learn how changing an exposition format can make Prometheus and OpenTelemetry-Collector more memory-efficient while making their specifications easier to translate into each other!

Practical Cloud Native Compliance Automation With OSCAL Compass - Chris Butler, Red Hat & Takumi Yanagawa, IBM Research

Tuesday June 17, 2025 15:50 - 16:20 JST

Cloud presents many advantages to users in terms of flexibility, scalability and innovation. Unfortunately compliance has become more complex as standards and regulations are used by end consumers as a proxy for security of underlying platforms whose operations are opaque. Consequently platform providers have ever increasing compliance obligations.

Compliance-as-code encompasses many activities such as automation of system configuration and general DevSecOps approaches. One perpetual challenge is how to provide machine readable workflows which span from standard to audit to allow automation in a way that scales.

OSCAL-Compass, a CNCF sandbox project, provides tooling to manage both the compliance artefacts as code and link those artefacts to executable policies. This talk will provide practical introduction to using OSCAL compass to document and enforce compliance controls using two of its tools: Compliance Trestle and C2P (compliance2policy) in the context of Kubernetes clusters.

From Moon Prism Power To eBPF Super Saiyan: A Guide To Cloud Native Security & Observability - Carla Gaggini, Isovalent at Cisco & Kenta Tada, Toyota Motor Corporation

Tuesday June 17, 2025 16:30 - 17:00 JST

Join us on an anime-powered journey to explore the power of eBPF in cloud native. Inspired by Sailor Moon and Dragon Ball GT, this talk breaks down how eBPF enhances observability, networking, and security, using the Sailor Guardians and Gohan to make eBPF approachable. We’ll break down topics like real-time observability by comparing it to psychic flames.
And just as unchecked power in anime can lead to chaos, eBPF’s immense capabilities need to be used wisely. Drawing from Dragon Ball GT's arc where the Dragon Balls become a threat, we’ll examine best practices for safe deployment of eBPF (e.g., LSM, verifier constraints, Linux Capability restrictions). Spoiler alert: our Sailor Guardians and Gohan will come out victorious, worry not!

By the end, you’ll gain a clear understanding of how to wield eBPF safely and effectively in cloud native environments, no Super Saiyan transformation required!

Dynamic Provisioning and Capacity-Aware Scheduling for Local Storage - Yuma Ogami, Cybozu, Inc.

Tuesday June 17, 2025 16:30 - 17:00 JST

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.

Your SBOM Is Lying To You – Let’s Make It Honest - Justin Cappos & Yuchen Zhang, New York University

Tuesday June 17, 2025 16:30 - 17:00 JST

SBOMs (Software Bills of Material) are essential for improving visibility and security in the software supply chain. As open-source code drives modern development, organizations face growing security risks due to limited transparency in software dependencies. Attacks like SolarWinds (2020) and Kaseya (2021) highlight the urgent need for stronger software supply chain security.
However, SBOMs are often inaccurate. This talk explores why these inaccuracies occur, how attackers exploit them, and how to address these issues. A key challenge is dependency management file analysis (e.g., cargo.toml for Rust), which struggles to track components effectively.
Enter SBOMit, an OpenSSF sandbox project leveraging in-toto attestations to create cryptographically verifiable SBOMs. By capturing supply chain steps as they occur, SBOMit enhances accuracy, mitigates tampering risks, and strengthens security. This talk examines SBOMit’s role in improving SBOM reliability across the CNCF ecosystem.
