A Comparative Analysis of Kueue, Volcano, and YuniKorn - Wei Huang, Apple & Shiming Zhang, DaoCloud

Wednesday April 2, 2025 11:15 - 11:45 BST

Level 1 | Hall Entrance N10 | Room G

Choosing the best solution for running batch workloads on Kubernetes can be frustrating. Kueue, Volcano, and Apache YuniKorn were designed to address similar challenges but differ in how they tackle them. Deciding which is most suitable for a specific use case is often confusing.

Batch workloads like big data, data engineering, HPC, AI, and machine learning share common requirements, especially around batch-scheduling. Managing resource sharing and isolation between tenants while balancing utilization and meeting SLAs presents a significant challenge on Kubernetes.

This session dives into three community-driven solutions: Kueue, Volcano, and Apache YuniKorn. We’ll explore their features, use-case suitability, and design trade-offs, providing a comprehensive comparison. Attendees will leave with the insights needed to answer a crucial question: which solution best addresses the batch-scheduling needs of my workloads?

OSS = Open Source ... Strategy!? Google Is Doubling Down on K8s in the AI Era, and You Should Too! - Jago Macleod, Google

Wednesday April 2, 2025 16:15 - 16:45 BST

Level 1 | Hall Entrance N10 | Room G

Kubernetes is Ten Years Old… Yikes - maybe it’s time to bail and find the next new hotness before it’s too late? Is it Ray? Or wait maybe it’s Spark or Run:ai or WASM or… ? Turns out it’s a trick question - all of these and more will play a role in the next hockey stick growth graph. And Kubernetes has a key role to play too.

I lead Open Source Kubernetes at Google. In this talk I’ll share our open source strategy and how it changed recently. I'll present the strategic framework and supporting pillars. I’ll share where we will focus our energy in the Kubernetes project in the next couple of years, and some concrete goals and risks. And I'll share how we rationalize work in open source in a world of limited resources.

The world has never changed so fast. Fortunately, the Kubernetes community created an extensible platform that is (just about) ready for the next trillion core hours. It’s not time to jump ship - we’re doubling down on Kubernetes and we think you will too.

Why Allyship Matters and Your Role in Creating a More Diverse Cloud Native Community - Catherine Paganini, Buoyant; Milad Vafaeifard, Epam Systems; Sandeep Kanabar, Gen; Anastasiia Gubska, BT Group; Rob Koch, Slalom Build

Wednesday April 2, 2025 17:00 - 17:30 BST

Level 1 | Hall Entrance N10 | Room G

Despite many DEI initiatives, diversity in open source is still lacking. That's not only bad for underrepresented groups, it's also bad for OSS (studies have shown time and again that diverse teams produce better outcomes). While there isn't much you can do about the industry's hiring practices, you can help make a difference!

As companies scale back on DEI efforts, community-driven change becomes essential—and that’s where allies come in. Minorities are, by definition, in the minority, and their advocacy alone has limits. Allies have the power to amplify underrepresented voices, raise awareness among peers, and advocate for change. When allies take a stand for inclusivity, accessibility, and ethical responsibility, they hold the power to influence the industry's values and priorities.

Join this panel with CNCF Deaf and Hard of Hearing WG members to learn how you can drive meaningful change and contribute to a more diverse, inclusive, and innovative open-source community.

Museum of Weird Bugs: Our Favorites From 8 Years of Service Mesh Debugging - Alex Leong, Buoyant

Wednesday April 2, 2025 17:45 - 18:15 BST

Level 1 | Hall Entrance N10 | Room G

Over the past 8 years we've fixed a lot of bugs in Linkerd. Many of these were straightforward, but some of them manifested in strange ways, or only showed up in unique situations, or otherwise surprised us. Some of them were just plain funny. In this talk we run through a couple of our favorites: the most interesting, weird, and memorable bugs we've found and fixed Linkerd. We describe how they originally manifested (usually in someone else's production system), how we went about tackling them (often by educating the reporter on how to construct a useful bug report), and the sometimes long and windy path to finally fixing them.

How To Adopt OpenTelemetry in an Enterprise Where Incumbent Vendor Tools Reign Supreme - Chris Weldon, Wolters Kluwer

Thursday April 3, 2025 14:15 - 14:45 BST

Level 1 | Hall Entrance N10 | Room G

OpenTelemetry isn't just an amazing set of tools and standards for observability - it's a useful ecosystem that's helped Wolters Kluwer to evolve our company from a monitoring strategy based on tool proliferation to an observability strategy with fewer, more purpose-specific tools.

In this session, you'll learn about Wolters Kluwer's 3-year journey to address high mean-time-to-resolution (MTTR) by adopting an observability strategy based on OpenTelemetry. We'll cover the technical tradeoffs for how we transitioned our portfolio of monolith and microservice applications from vendor-locked tools to open standards and a narrowed tool selection. We'll review challenges we encountered along the way, and how our platform-as-a-product mindset is helping to drive adoption of these open standards across the organization and improving our MTTR.

How To Rename Metrics Without Impacting Somebody’s Observability - Bartłomiej Płotka, Google & Arianna Vespri, Independent

Thursday April 3, 2025 15:00 - 15:30 BST

Level 1 | Hall Entrance N10 | Room G

Metrics are a core aspect of modern cloud-native observability and monitoring. With the Prometheus project, it’s easy to create metrics and adopt existing ones from applications or exporters. It's easy to build layers of tools, alerts, dashboards and integrations that depend on specific metrics. Unnoticed, metric names and labels became an API contract between instrumentation and consumers.

However, second-day operations kick in! New standards, naming opinions and software versions force metrics to be changed, causing major downstream breakages. Projects like Kubernetes or OpenTelemetry started frameworks to raise awareness about this problem. Can we do more?

In this talk, Bartek (Prometheus maintainer) and Arianna (Prometheus client_golang maintainer) will explore renaming strategies for Prometheus and OpenTelemetry end users. Finally, they will discuss existing conventions and frameworks for stable metric versioning that could be adopted by the next generation of instrumentation.

Observability Pipeline Query Languages: Present and the Future - Jacek Migdal, Quesma

Thursday April 3, 2025 16:45 - 17:15 BST

Level 1 | Hall Entrance N10 | Room G

Many observability products have created their query languages, starting with Splunk and followed by a parade of incompatible options (Sumo Logic, Coralogix Dataprime, Grafana LogQL, Elastic ES/QL, OpenSearch PPL, to name a few). I’ll admit I’m one of the culprits who contributed to this fragmented landscape. Even PromQL, a well-known open-source option for time-series data, hasn’t reached the universal adoption levels of good old SQL.

Is there a way to untangle this mess and march toward some standardization? In this piece, I’ll dive into a few proposals, including concepts like “pipe SQL” and ideas floating around in CNCF forums, to see if there’s a glimmer of hope for alignment.

The Missing Metrics: Measuring Memory Interference in Cloud Native Systems - Jonathan Perry, PerfPod

Friday April 4, 2025 11:00 - 11:30 BST

Level 1 | Hall Entrance N10 | Room G

Your applications may be suffering from severe performance degradation without you knowing it. Memory bandwidth contention and cache interference between containers can increase tail latency by 4-13x and reduce compute efficiency by 25%, even with CPU and memory limits in place. This effect is particularly insidious as it manifests as high CPU utilization, leading operators to misdiagnose the root cause.

This session presents the latest research on detecting memory interference, including findings from Google, Alibaba, and Meta's production environments. We'll explore how modern CPU performance counters can identify noisy neighbors, examine real-world patterns that trigger interference (like garbage collection and container image decompression), and demonstrate practical approaches to measure these effects in Kubernetes environments.
