Sponsored Keynote: Towards Clouds of AI Clusters - Bill Ren, Huawei Chief Open Source Liaison Officer, Board member of CNCF

Tuesday June 10, 2025 09:36 - 09:41 HKT

AI is quickly becoming the most important workload in our clouds. However, AI is not like other cloud native workloads. Whereas before, clouds could manage elastic resources that easily and cheaply scaled out, AI workloads do not readily support this. AI hardware infrastructure is moving towards large clusters of processors, is not readily scaled out, is not readily available on-demand, and is much more expensive. This requires significant changes to how we build and
manage our clouds, from the operating system up to our cloud native infrastructure. This talk will highlight how this evolution towards clouds of AI clusters is happening through projects such as Linux, Volcano, and Karmada.

Keynote: An Optimized Linux Stack for GenAI Workloads - Michael Yuan, WasmEdge

Tuesday June 10, 2025 09:43 - 09:53 HKT

Keynote Sessions, Emerging + Advanced

Running GenAI workloads on Linux is a challenge due to the complexity of AI runtime toolchains and dependencies of heterogeneous GPU devices. The problem is especially acute in containers where the host and guest OSes must have compatible versions of GPU drivers and application software stacks.

CNCF’s Flatcar Linux project aims to simplify containerized Linux deployment. It has an immutable system that can be optimized for both host and guest systems. Furthermore, it supports cross-platform and cross-GPU Wasm workloads. As Wasm runtimes such as WasmEdge and LlamaEdge support a wide range of AI models, Flatcar Linux has become a good candidate for running GenAI workloads in containers.

In this talk, we will cover the basics of Flatcar and its support for Wasm runtimes. We will also discuss WasmEdge’s support for portable AI models and inference applications. Finally, we will give a demo of a complete GenAI app running in Flatcar across GPUs and CPUs.

From Bottleneck To Breakthrough: Conquering Applications Startup Peaks in Kubernetes - Hexi Guo, Alibaba Cloud & Rentian Zhou & Zhuoqi Liu, CloudPilot AI

Tuesday June 10, 2025 13:45 - 14:15 HKT

Level 19 | Crystal Court II

A variety of applications in Kubernetes typically require higher memory or compute resources during startup—such as Java, .NET, and Node.js applications, as well as those utilizing large data processing frameworks or machine learning models—due to the need to load substantial dependencies and perform complex initialization tasks. To prevent startup failures from resource contention, these applications typically have their resource requests set based on peak startup demands. However, this often leads to resource waste after startup is complete.
To address this challenge, this session presents a queue-based approach using Karpenter. This method allows applications set resource requests based on typical usage instead of peak startup needs. It temporarily spreads applications across multiple smaller nodes during startup, preventing single-node overload. After startup, it smoothly consolidates them onto fewer but larger nodes to optimize resource usage while maintaining service stability.

Keynote: Key Cloud Native Technologies in its Next Decade - Lin Sun, Head of Open Source, Solo.io

Wednesday June 11, 2025 09:24 - 09:34 HKT

When we started CNCF in 2015 to help advance container technology, Kubernetes was the seeding technology to provide a de facto container orchestration platform for all cloud native applications. Almost a decade later, the community has exploded with 200+ open source projects building on top of cloud native technologies. Looking ahead, what challenges will we have in the next decade? What gaps remain for users and contributors? And how do we evolve to meet the demands of an increasingly complex and connected world?

Let us review some of the key CNCF projects today and lay out some possible avenues for where cloud native is going for the next decade, AI, agentic network, sustainability and beyond.

Unified Observability in GRPC: Metrics and Tracing Using OpenTelemetry Plugin - Purnesh Dixit, Google

Wednesday June 11, 2025 11:00 - 11:30 HKT

gRPC’s performance advantages hinge on minimizing latency, but its binary protocol and streaming capabilities make debugging and monitoring inherently opaque. While distributed tracing identifies bottlenecks, metrics like error rates and throughput are critical for holistic insights. Yet, manual instrumentation for these signals in gRPC is complex, error-prone, and lacks standardization.

In this talk, Purnesh Dixit from the gRPC team unveils the new OpenTelemetry plugin for gRPC, developed by the gRPC team at Google, which provides unified metrics and tracing out-of-the-box to monitor retries, diagnose streaming bottlenecks, and optimize performance without invasive code changes.
1) Client-per-call: Track overall RPC lifecycle (e.g., grpc.client.call.duration).

2) Client-per-call-attempt: Analyze individual retries/hedges (e.g., grpc.client.attempt.duration).

3) Server-instruments: Measure concurrency, request queuing, and stream lifetimes (e.g., grpc.server.call.started).

How Bloomberg Creates a Resilient Data Analytics Platform Using Karmada - Michas Szacillo & Ilan Filonenko, Bloomberg

Wednesday June 11, 2025 11:45 - 12:15 HKT

Level 19 | Crystal Court II

Bloomberg’s Data Analytics Platform Engineering team supports a wide-range of real-time streaming, large batch ETL, and data exploration use-cases by using Apache Flink, Apache Spark, and Trino across multi-cluster Kubernetes. However, deploying and managing these workflows at scale efficiently can be challenging due to varying resource requirements and uptime needs. For stateful applications like Apache Flink, ensuring recovery and state conservation after downtime is especially important.

This session will discuss how Bloomberg uses Karmada, a multi-cluster management system, to deploy and manage Apache Flink. We’ll also explore how Karmada’s capabilities can be expanded to handle additional data analytics workloads, including Apache Spark and Trino. The session will cover the unique requirements and real-life use-cases for each, including:

- Resource-aware workload scheduling
- Custom resource requirements and health interpretation
- State conservation during application failover

Kube Intelligence - A Metric Based Insightful Remediation Recommender - Yash Bhatnagar, Google

Wednesday June 11, 2025 11:45 - 12:15 HKT

Level 19 | Crystal Court I

Not everything can be thought about while designing or developing the applications, and as such lot of the design decisions are based on estimates and potential usage patterns.

More often that not, these estimates differ from reality and introduce inefficiencies in the system across several fronts - and if at all visible, it always much later in the lifecycle when you already have several customers & high footprint.

And hence, unless there is a clear sign of performance degradation or unjustified costs, there is often no incentive to invest time & effort for some unknown gains.

In this session Yash will outline a real world case study about how they went about building an internal platform for handling several aspects of post deployment challenges like

1. rightsizing opportunities,
2. architecture migrations like moving to serverless,
3. finding right maintenance windows, etc

by using a wide range of metrics, and how impactful these minor optimizations turned out to be.

Progressive Delivery Made Easy With Argo Rollouts - Kevin Dubois, Red Hat

Wednesday June 11, 2025 13:45 - 14:15 HKT

Level 19 | Crystal Court I

ou might already be using a CI/CD solution, but are you 100% sure things will roll out without a glitch once you go to production? Unfortunately differences between testing/staging and production environments are virtually unavoidable. There’s always a risk for unforeseen issues related to your production environment and/or actual load which can lead to potential disruptions to your users.

Progressive delivery is the next step after Continuous Delivery to roll out your application in a controlled and automated way so you can verify and test your application *in production* before it becomes fully available to all your user bases.

Embrace GitOps and Progressive Delivery with techniques like blue-green, canary release, shadowing traffic, dark launches and automatic metrics-based rollouts to validate the application in production using Kubernetes and tools like Istio, Prometheus, ArgoCD, and Argo Rollouts.

Come to this session to learn about Progressive Delivery in action using Kubernetes.

The Past, the Present, and the Future of Platform Engineering - Mauricio "Salaboy" Salatino, Diagrid & Viktor Farcic, Upbound

Wednesday June 11, 2025 14:30 - 15:00 HKT

Level 19 | Crystal Court I

Do you think platform engineering is too hard? Or is it just a buzzword? Is the CNCF landscape too tricky to visualize? If you’ve been in this industry long enough, you should know that platform engineering has been around for a long time.

Most of us have been trying to build developer platforms for decades, and most of us have failed at that. That begs the questions: “What is different now?” “Why will this time be different?” and “Do we have a chance to succeed?”

We’ll take a look at the past, the present, and the future of platform engineering. We’ll see what we were doing in the past, what we did wrong, and why we failed. Further on, we’ll see what we (the industry as a whole) are doing now and, more importantly, where we might go from here.

Get ready for the hard truths and challenges you will face when trying to build a platform based on Kubernetes. Join us for a pain-infused journey filled with challenges teams will face when building platforms to enable other teams.

Guardians of Multi-Tenancy: Enhanced Authorization To Prevent Lateral Node Escape - Dahu Kuang & Cheng Gao, Alibaba Cloud

Wednesday June 11, 2025 14:30 - 15:00 HKT

Maximizing security in multi-tenant clusters while maintaining cost-effectiveness is crucial for enterprise OPS. Most enterprise clusters deploy multiple daemonsets, which are attractive targets for attackers seeking to escape and move laterally, ultimately taking over the entire cluster.

The SIG community has introduced several advanced security features recently, such as CRD Field Selectors, Field and Label Selector Authorization, validating admission policy (VAP), and Structured Authorization Config. These allow users to define more flexible authorization configurations, addressing filtering and authorization needs for CRDs, kubelet, and other resources in multi-tenant environments.

We will share the lessons learned from the node escape incidents and demonstrate how to implement these new features and show how to use the Common Expression Language (CEL) to configure customized policies in Authorization Webhook and VAP, resulting more node-specific restrictions within clusters.

Policy as Code: Past, Present and Future for Novice - Hoon Jo, Megazone

Wednesday June 11, 2025 15:30 - 16:00 HKT

Policy as Code Past, Present and Future for Novice v1.0.0 pdf

When you're new to Kubernetes, Policy as Code (PaC) can be a very unfamiliar topic. But as you get more familiar with Kubernetes, you'll probably be interested in how you can use it securely, especially since Kubernetes is essentially a declarative system via YAML, so having security also be done in code will help with usability and reducing human error.

In order to make PaC easier to understand, I'll demonstrate the Admission Control part directly in Kubernetes. Until recently, this part was based on webhooks, but since v1.23, the decision to actively embrace the Common Expression Language (CEL) has made it possible to apply it as code directly inside Kubernetes. Validating Admission Policy became GA in v1.30, and Mutating Admission Policy is in Alpha in v1.32.

Based on this outline, I'll talk about how PaC has been applied to Kubernetes in the past, how it works today, and finally, how we can expect it to be integrated into Kubernetes in the future.

See you at the session! 🙂
