Wasm I Right or Wasm I Wrong? a Review of the Wasm Ecosystem - Taylor Thomas, Cosmonic & David Justice, Microsoft

Wednesday April 2, 2025 12:00 - 12:30 BST

Level 3 | ICC Capital Suite 14-16

WebAssembly (Wasm) has long been touted as the next era of compute, with its portability, security, and efficiency. But many people still question if it is ready for production usage. Once rooted in browsers, Wasm has found a home at the edge, in serverless platforms, and in many of the CNCF projects you know and love. Early experiments often meant fumbling with custom ABIs, but the advent of the component model makes interoperability and composability a breeze. In this talk, David and Taylor, two of the Wasm WG chairs, will cover Wasm’s journey from its browser origins to its role as a building block of cloud-native applications. They’ll show how CNCF projects are leveraging Wasm today, from spinning up services to extending existing stacks, all without getting bogged down in bespoke ABIs. Then they’ll finish with a candid discussion about the component model, its strengths and weaknesses, and how you can successfully use it in your projects today.

SIG-Node: Intro and Deep Dive - Sergey Kanzhelev & Dixita Narang, Google; Francesco Romani & Peter Hunt, Red Hat

Wednesday April 2, 2025 15:15 - 15:45 BST

Level 3 | ICC Capital Suite 14-16

This session covers the latest updates in the Kubernetes Node subsystem. SIG Node owns components like Kubelet, Container Runtime Interface (CRI), Node API. SIG Node is responsible for Pod lifecycle from allocation to teardown, shared (“classic”) resource management, topology alignment and device access via device plugins. SIG Node is also a major contributor of the Dynamic Resource Allocation (DRA) which is becoming the bedrock of the new generation or resource management. We work with container runtimes, kernels, networking, storage, and more; anything between the pod and the underlying hardware that runs them is in SIG Node’s purview!

The session will be interesting for end users, seasoned contributors, and people seeking to get involved. Attendees will leave the session with a better understanding of the latest developments like DRA, PSI, pod level resources, in-place VPA and more, as well as understand the roadmap in these days of AI/ML and other workloads adoption.

Kubeflow Ecosystem: What’s Next for Cloud Native AI/ML and LLMOps - Johnu George, Nutanix; Andrey Velichkevich, Apple; Amber Graner, Kubeflow Project; Yuki Iwai, CyberAgent; Yuan Tang, Red Hat

Thursday April 3, 2025 11:00 - 11:30 BST

Level 3 | ICC Capital Suite 14-16

Over the years, Kubeflow has become one of the most widely adopted ML platforms on Kubernetes, managing the entire AI/ML lifecycle, from pipeline orchestration and data processing to distributed training, tuning, and inference. The challenges in the MLOps domain evolved over time with newer ML models and advancements in infrastructure capabilities. With the recent GenAI wave, users want to train and deploy custom LLMs on public clouds or on-premises infrastructure. Unlike traditional ML models, LLMs are massive, requiring significant data processing and computing resources for training and inference. The Kubeflow community has been working hard to provide first-class citizen support to generative models and their core abstractions, focusing more on LLMOps. In this talk, the speakers will discuss the requirements for the next-generation ML platform, its current shortcomings, the roadmap to solving these challenges and how you or your organization can contribute to Kubeflow’s success.

How We Solved TLS at Scale: Self-Service, Multi-Tenant Cert-manager - Erik Godding Boye, Zenior & Tim Ramlot, Venafi, a CyberArk Company

Thursday April 3, 2025 17:30 - 18:00 BST

Level 3 | ICC Capital Suite 14-16

cert-manager is an open-source X.509 certificate controller for Kubernetes, designed to automate certificate management. In this session, we’ll explore how to configure cert-manager and its subprojects for large-scale certificate management.

At the scale of our production setup, managing and requesting certificates cannot be centralized and self-service is required. A self-service multi-tenant setup requires isolation between tenants, must support tenant-specific trust, and must be able to enforce security policies at scale.

We'll make use of key cert-manager subprojects including trust-manager, approver-policy, and csi-driver to simplify these challenges. You’ll walk away knowing how to use cert-manager in multi-tenant setups, leaving you free to focus on your all-important business logic!

Cloud Native AI: Harness the Power of Advanced Scheduling for High-Performance AI/ML Training - William Wang & Xuzheng Chang, Huawei

Friday April 4, 2025 11:45 - 12:15 BST

Level 3 | ICC Capital Suite 14-16

In the era of large models, as models and data are becoming increasingly larger, LLM workloads have extremely high requirements for network throughput and latency.

However, Kubernetes has no awareness of either the parallel models of LLM workloads or the underlying high-speed network communication topology, which leads to a loss in training performance. Meanwhile, many expensive high-performance underlying resources are not utilized more efficiently.

As one of the important projects for Cloud-native AI, Volcano has conducted in-depth research over the past year. It has remodeled the workloads in large model training and inference scenarios as well as the new network topologies, and designed and implemented high-performance scheduling features.

This talk will cover：
1. The complexities related to intelligent scheduling, improving performance and cost-effective
2. Methodology to reconsider the resource model and LLM workload
3. Enhancement to Volcano to optimize training for AI/ML
