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
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.

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.

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!

⚡ 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.

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!

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.

Cloud Native Scalability for Internal Developer Platforms - Hiroshi Hayakawa, LY Corporation
Tuesday June 17, 2025 12:10 - 12:40 JST
Level 1 | Orion
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.

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.

Mastering Authorization: Integrating Authentication and Authorization Data in Cloud Native Apps - Yoshiyuki Tabata, Hitachi, Ltd.
Tuesday June 17, 2025 14:50 - 15:20 JST
Level 1 | Pegasus B2-C
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.

Reimagining Cloud Native Networks: The Critical Role of DRA - Lionel Jouin, Ericsson Software Technology & Sunyanan Choochotkaew, IBM Research
Tuesday June 17, 2025 15:50 - 16:20 JST
Level 1 | Orion
As AI/ML, high-performance and telecom workloads are progressing in their cloud-native journey, the unique platform requirements inherent to the nature of their functionality are exposing the limitations of existing solutions such as Multus and device plugins. Device Resource Allocation (DRA) offers a fresh approach overcoming these challenges with better resource management for non-homogeneous platforms, topology-aware use cases and beyond! By leveraging the latest Kubernetes features, DRA Drivers are redefining the network interface configuration and enhancing capabilities for multi-network deployments. This talk explores the evolving cloud-native networking landscape and the trade-offs between extending Kubernetes and leveraging add-on components. We will delve into recent advancements including the network device status with KEP-4817, the virtual device allocation with KEP-5075 and the role of the CNI-DRA-Driver in shaping the future of cloud-native networking infrastructure.

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
Level 1 | Pegasus B2-C
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.

Dynamic Provisioning and Capacity-Aware Scheduling for Local Storage - Yuma Ogami, Cybozu, Inc.
Tuesday June 17, 2025 16:30 - 17:00 JST
Level 1 | Orion
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.
