AI Model Distribution Challenges and Best Practices - Wenbo Qi & Xiaoya Xia, Ant Group; Eryu Guan, Aliyun; Wenpeng Li, Alibaba Cloud; Han Jiang, Kuaishou

Tuesday June 10, 2025 11:00 - 11:30 HKT

Level 19 | Crystal Court I

As the demand for scalable AI/ML grows, efficiently distributing AI models in cloud-native infrastructure has become a pivotal challenge for enterprises. The panel dives into the technical and operational strategies for deploying models at scale -- from optimizing model storage and transfer to ensuring consistency across clusters and regions. Experts from different companies and CNCF projects will debate critical questions like: How can Kubernetes-native workflows automate and accelerate model distribution while minimizing latency and bandwidth costs? How to efficiently distribute huge models sizing hundreds of GBs or TBs? What are the challenges proposed by distributed inference and the prefilling-decoding architecture? How are models updated in the reinforcement learning post-training paradigm? What role do standards like OCI artifacts or specialized registries play in streamlining versioned model delivery?

⚡ Lightning Talk: Advanced GPU-Orchestrated Workflows and HPC Integrations on K8s for Distributed AI/ML at Scale - Brandon Kang, Akamai Technologies

Tuesday June 10, 2025 15:37 - 15:42 HKT

Level 16 | Grand Ballroom I

As AI/ML workloads continue to scale in complexity, developers and platform engineers are pushing Kubernetes beyond typical MLOps boundaries.

This talk dives into strategies for orchestrating GPU-accelerated training and inference across large-scale clusters -integrating HPC principles, operator-based scheduling, and novel debugging workflows.

Attendees will learn how to implement fine-grained GPU partitioning, harness ephemeral containers to probe and adjust multi-node training in real time, and adopt eBPF-driven instrumentation for low-overhead kernel-level performance insights. We’ll explore cutting-edge scheduling optimizations—like reinforcement-learning approaches and HPC-inspired batch-queuing orchestration on Kubernetes that dynamically respond to heterogeneous job demands.

Real-world case studies will highlight HPC integration scenarios (RDMA, GPU Direct) for data-parallel workloads and complex training frameworks such as Horovod, Ray, and Spark on Kubernetes.

⚡ Lightning Talk: Stateful Service Federation in Large-Scale Search, Ads, and Recommendation Scenarios at Xiaohongshu - Yang Song & Vec Sun, Xiaohongshu

Tuesday June 10, 2025 16:40 - 16:45 HKT

Level 16 | Grand Ballroom I

Search, advertising, and recommendation services are among the primary business types within Xiaohongshu. Due to the strong dependency of these services on index table, each instance replica needs to maintain its own independent state. As a result, such services are deployed using the stateful workload.
With the rapid growth of Xiaohongshu's business scale, the size limit of a single Kubernetes cluster has made it impossible to further scale stateful services. To address daily traffic and business growth, the only solution was to migrate workloads to idle clusters. However, this migration approach has caused significant inconvenience and risks for developer.
To tackle this challenge, Xiaohongshu leveraged Karmada to implement the federation of stateful services. By designing scheduling and deployment capabilities for stateful services on federated clusters, This approach has seamlessly resolved the scaling limitations caused by single-cluster capacity constraints for stateful services.

Portrait Service: AI-Driven PB-Scale Data Mining for Cost Optimization and Stability Enhancement - Yuji Liu & Zhiheng Sun, Kuaishou

Tuesday June 10, 2025 17:00 - 17:30 HKT

Level 19 | Crystal Court I

Kuaishou's Kubernetes-based platform manages 200,000+ machines and 10M+ Pods, generating 10TB+ daily data. AI-driven intelligent portrait service enhances stability and performance:
● Stability Management: AI analyzes system and workload metrics to generate machine health scores, integrated into Kubernetes scheduling to evict/avoid unhealthy nodes. This reduced pod creation delays from 20 to 0.1 cases/day and boosted service availability from 90% to 99.99%.
● Performance Optimization:
Serving 10,000+ services with diverse resource sensitivities (compute-, cache-, and IO-intensive), we combine AI with microarchitecture data to pinpoint bottlenecks and create application profiles. Optimizing resource allocation (compute, cache, memory bandwidth) has increased average IPC by 20% and reduced LLC miss rates for cache-sensitive services from over 50% to 10%.
Future plans include integrating AI Agent technology to automate anomaly detection and reduce manual operations by 80%.

Tuesday June 10, 2025 17:08 - 17:12 HKT

Level 16 | Grand Ballroom I

What does the future of AI look like when we push the boundaries of cloud-based models and take it to the edge? In this talk, we’ll explore how Wasm and edge computing power AI deployment by providing developers with a fast, lightweight, and secure framework for running machine learning models across devices.

We’ll focus on how Wasm enables AI models to run efficiently on edge devices like NVIDIA GPUs, Mac, etc, driving LLM agents that require low latency and high throughput. This session will demonstrate the scalability of Wasm when integrated into distributed systems for AI processing, showing how the combination of edge computing and Wasm allows for faster, responsive AI applications that don’t rely on centralized cloud resources.

We’ll showcase real life use cases such as AI streamers commenting in real time, video translation agents deployment. Developers will walk away with an understanding of how to combine Wasm with edge infra to build and deploy AI apps that scale seamlessly

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

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

Level 16 | Grand Ballroom I

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! 🙂
