Kubeflow Ecosystem: Unleash the Power of Cloud Native AI - Andrey Velichkevich & Luciano Resende, Apple; Yuki Iwai, CyberAgent, Inc; Valentina Rodriguez Sosa, Red Hat

Tuesday June 17, 2025 11:30 - 12:00 JST

Level 1 | Appollon

Since 2017, the Kubeflow community has embraced Kubernetes as the foundation technology for AI/ML workloads. Over the years, Kubeflow and Kubernetes communities have worked closely to make cloud native tools more accessible for AI/ML.

Today, Kubeflow ecosystem of projects covers entire AI/ML lifecycle - from data processing and feature engineering to large-scale LLM fine-tuning, optimization, and serving.

Its modular, microservice-based architecture gives organizations the flexibility to adopt specific tools or deploy the full Kubeflow distribution as a comprehensive ML platform.

In this session, speakers will share key updates from the latest Kubeflow 1.10 release, including new additions to the Kubeflow ecosystem, like Feast and community-driven initiatives to enhance the GenAI on Kubernetes with ML Experience working group, Kubeflow SDK, and LLM fine-tuning blueprints. Join us to see how the Kubeflow community continues to drive innovation in cloud native AI and LLMOps.

WG-Batch Updates: What’s New and What Is Next? - Michał Woźniak, Google & Yuki Iwai, CyberAgent, Inc

Tuesday June 17, 2025 12:10 - 12:40 JST

Level 1 | Appollon

Join WG Batch maintainers for an in-depth look at the latest improvements in the Kubernetes ecosystem for HPC, AI/ML, and large-scale data analytics.

Yuki and Michał will present Kueue, a Kubernetes subproject enabling multi-tenant workload scheduling and advanced resource management, highlighting the new enhancements such as Topology-Aware Scheduling, Multi-Cluster Job dispatching, and Fair Sharing. They will also share updates on the Kubernetes Job API, as well as the JobSet API which is going to be the foundation for the Kubeflow Trainer v2. Additionally they present the new CLI tools, kjob and kueuectl, to make it easier for ML researchers to iterate running their workloads using Kubernetes with Kueue.

The WG Batch was created in 2022 to address the rapidly growing need for the first-class support of batch workloads in Kubernetes. It unites experts from multiple SIGs and diverse communities with the objective to define roadmaps and to collaborate on designs and implementations.

What's New in Open Source Kubernetes? - Kaslin Fields, Google

Tuesday June 17, 2025 14:10 - 14:40 JST

Level 1 | Appollon

Kubernetes moves fast. With 3 releases per year, it's hard to keep up with what's new in open source - not to mention whatever distributions or managed services you may use on top of it. This session will explore some of the most exciting changes to Kubernetes over the last couple of years including:
* New features to support AI workloads
* The introduction of a native way to implement the Sidecar Pattern
* Removal of "In-Tree" Cloud & Storage Provider code
* The deprecation of Pod Security Policies (PSPs) and introduction of Pod Security Admission
* The transition of image registry from k8s.gcr.io to registry.k8s.io
and more!
