Keynote: Platform Alchemy: Transforming Kubernetes Into Generative AI Gold - Alexa Griffith, Bloomberg & Mauricio "Salaboy" Salatino, Diagrid
Monday June 16, 2025 09:42 - 09:52 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 09:54 - 09:59 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 10:01 - 10:11 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 10:13 - 10:18 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.

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.

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!

⚡ 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.

Monday June 16, 2025 14:17 - 14:22 JST
Level 1 | Pegasus A-B1
While typical web applications do not require large amounts of resources constantly, there are cases where specific processes consume significant CPU and memory.
In this session, we will introduce an architecture that offloads such resource-intensive processes to Kubernetes Jobs.
We will explain specific methods for Job management, how to integrate web applications (Next.js, @kubernetes/client-node) with the Kubernetes API, methods for data integration between Jobs and web applications, and real-time tracking of Job progress in the UI, all while sharing practical examples. Furthermore, we will provide a detailed introduction to a pattern where Kubernetes Job definitions generated from applications are managed using ConfigMaps, enabling quick configuration switching between environments, and offer hints to optimize your applications in terms of cost, performance, and management.

⚡ 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: Enhanced Service Redirection: eBPF Ensures the High Availability of Node-Local DNS - Weizhou Lan, Daocloud
Monday June 16, 2025 14:31 - 14:36 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: 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.

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.

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.

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.

Keynote: Engineering Without Limits: A Decade of Kubernetes Powering PlayStation’s Evolution - Chris McEniry & Swathi Somanchi, Sony
Tuesday June 17, 2025 09:56 - 10:01 JST
Level 1 | Pegasus A-B1
8 year ago, we started to release Playstation products powered on top of Kubernetes. At the time, it was focused on accelerating our time to market. Little did we know that it would also provide the rallying flag for bringing together multiple parts of the organization to work in a consistent manner. With common features available to all application teams, they could focus on improving the game and game developer experience, instead of re-inventing toiling wheels.

As we look to the future, we're once again able to use the Kubernetes ecosystem as a rallying point. It's enabling us to expand our availability and capabilities into new hosting environments. We're moving up the value chain by replacing once novel but now bespoke components with modern and now commodity logic.

In this talk, we'll summarize our experience bringing a common platform to Sony Interactive Entertainment, what the future holds, and how the past, present and future help Playstation to continue to provide a gaming world where Play has no Limit.

Green OpenTelemetry: Have Your Cake and Eat It Too - Adriana Villela, Dynatrace
Tuesday June 17, 2025 14:50 - 15:20 JST
Level 1 | Pegasus A-B1
It’s a not-so-dirty little secret that the technology that we so heavily rely on comes at an environmental cost. As technology becomes more complex, we need Observability to better understand it, and yet this too contributes to an increasing global tech carbon footprint.

Luckily, we have tools at our disposal that can help us understand our carbon footprint, and take mitigating actions. Tools like Kepler, Kube-Green, and green reviews.

In this talk, attendees will learn about Kepler, Kube-Green and green reviews. They will learn how to use these tools to make tweaks to their OpenTelemetry Collectors and other Kubernetes infrastructure. This will therefore keep systems observable while keeping the environment in mind.

The Future of Prometheus Exposition Format - Arthur Sens, Grafana Labs
Tuesday June 17, 2025 15:50 - 16:20 JST
Level 1 | Pegasus A-B1
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!

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
Level 1 | Pegasus A-B1
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!
