The Power of Consolidation: A Unified Stack for Business Intelligence, Security, and Observability - Josh Lee, Altinity, Inc. & Mya Jaye, C8 Labs

Monday June 23, 2025 11:20am - 12:00pm MDT

Bluebird Ballroom 2G

Imagine you’re responding to a production incident, and you’re trying to answer simple questions about it. How many systems do you need to consult when assessing the impact of events at your company? Do you manage different technology stacks for observability, security, and business intelligence?

What if we told you, you could create a unified stack capable of serving all stakeholders simultaneously? In this talk, Mya and Josh explore how open source technologies like ClickHouse, OpenTelemetry, and Grafana enable complex business use cases using modern tooling and practices.

Regardless of your function, you will leave with a deeper understanding of how consolidating these concerns into a unified stack reduces technical complexity and provides a common language for everyone to use - from engineers building new features and product managers evaluating their success, to operators keeping the lights on and C suite’s birds-eye view of the company.

Whether you’re working with a data lake, or more of a data pond, we offer practical architectures and solutions to streamline your operations and bring your stakeholders together, all while using fewer resources.

Gopher Meets Crab: A Rust Journey in Cloud Native - Phil Estes, AWS

Monday June 23, 2025 1:30pm - 2:10pm MDT

Bluebird Ballroom 2G

If you've been around the container and cloud native ecosystem for any length of time, you know most major components are written in Go: from Docker to runc and from Kubernetes to etcd! This means that many of the common constructs, for example the OCI specs, or Kubernetes API resources, are easy to use from other Go programs, but not quite as easy when you step outside of the Go ecosystem.

In this talk we'll dive into the experience of trying to use containers from a Rust-written client and delve into existing work from early adopters of Rust. There are quite a few crates that help us along the way, providing some level of parity for Rust developers in the cloud native ecosystem. There are still complexities and hurdles as well, and we'll share our experience navigating this as a long-time Go programmer and Rust newbie.

Attendees will take away some quick tips as well as gotchas for working in the container and cloud native ecosystem as a Rust developer and, who knows, maybe soon the Gopher and the Crab will be the best of friends.

EdgeLake: Extending the Cloud To the Edge – an LF Edge Project - Moshe Shadmon, AnyLog

Monday June 23, 2025 2:25pm - 3:05pm MDT

Bluebird Ballroom 2G

As data volumes grow and real-time processing becomes essential, traditional cloud architectures face limitations in cost, latency, and security. The traditional approach moves all edge data to where the queries are executed—in the cloud—leading to inefficiencies and high costs. EdgeLake (https://lfedge.org/projects/edgelake/), an LF Edge project, takes the opposite approach by bringing queries to the source data at the edge, enabling decentralized data management and local AI/ML processing.

In this talk, we’ll explore how EdgeLake eliminates cloud dependencies, optimizes data infrastructure, and reduces operational costs while ensuring real-time decision-making at the edge. We’ll discuss key use cases (and show a live demo) across industrial automation, smart cities, energy, and telecom, demonstrating how organizations can leverage EdgeLake to unlock the full potential of edge computing.

Join us to learn how EdgeLake is reshaping the future of distributed data architectures and making edge intelligence more accessible.

A Brief History of Kubernetes Fleet Controllers & Essential Features - Mickael Alliel, Komodor

Monday June 23, 2025 3:35pm - 4:15pm MDT

Bluebird Ballroom 2G

Managing a few Kubernetes clusters may be feasible, but scaling up to hundreds or thousands introduces unique challenges. At a 100:1 cluster to engineer ratio, standardization, observability, security, and access control become pressing issues. This is when DevOps must shift from "infrastructure engineers" to "platform engineering," where infrastructure needs are fully automated and self-service.

As K8s adoption grows in large organizations, demand for "massive multi-cluster fleet management" support has intensified. This talk examines essential features for Kubernetes fleet controllers, offering a fast-paced review of five open-source tools: Clusternet, Karmada, Crossplane, ClusterAPI, and Rancher. Each tool's unique strengths in provisioning, management, and application support will be covered, showing how each addresses multi-cluster management challenges.

This approach will provide a replicable framework to evaluate & choose the right tools based on specific organizational needs.

Towards Confidential AI for the Masses! - Julian Stephen & Michael Le, IBM

Tuesday June 24, 2025 11:00am - 11:40am MDT

Bluebird Ballroom 2G

Confidential AI leveraging GPUs can bring AI to the masses without sacrificing the privacy of end users. Individual open source technologies already exist to configure, deploy, and manage confidential TEEs. However, clobbering a multitude of components into a coherent, secure, and efficient solution is challenging with many pitfalls. For example, depending on use cases and involved parties (cloud/model/service owners), attestation and key management methodology can vary drastically. In addition, for TEEs with confidential GPUs, complexity extends to increased load times, affecting services that serve multiple models.

This talk will go through key components and design decisions needed to enable confidential AI. Specifically: i) implications of different trust models on the solution and (ii) performance tradeoff considerations. To concretize the discussion, we will present a detailed end-to-end 'how to', for deploying an inference service on Nvidia H100 GPUs and AMD-based TEE with a focus on protecting the model and the user input. The audience will be able to appreciate why there can be no one size fit all confidential AI solution and understand what design works for them.

Cross-cloud App Splitting With WebAssembly Components - Matt Butcher, Fermyon

Tuesday June 24, 2025 11:55am - 12:35pm MDT

Bluebird Ballroom 2G

Take one single application compiled to WebAssembly and split it into pieces at deployment time. Run these pieces in different Kubernetes deployments, different clouds, or even split across edge and cloud.

This code-forward talk will show how to write an application using Wasm components and a combination of Rust and TypeScript. We'll show how to use the CNCF project Spin for developing apps, and then use Kubernetes, Helm, SpinKube, and other open source tools to deploy this application in multiple locations.

Conceptually, we'll tie this new development pattern to microservice architecture and distributed systems to show how WebAssembly's Component Model is paving the way for a new class of application.

Let’s Farm Out Our Image Builds! - Urvashi Mohnani, Red Hat

Tuesday June 24, 2025 2:10pm - 2:50pm MDT

Bluebird Ballroom 2G

As the fast-paced AI-driven landscape of computing continues to diversify, the importance of multi-arch container images cannot be overstated. Applications are no longer confined to data centers but extend across multiple platforms, devices, and appliances.

Wouldn’t it be great if we could build images for every architecture from just one machine? It would be even more amazing if we could do that without the slowness of emulation! This is where Podman farm comes in. Podman farm is a new feature that allows you to 'farm' out builds to groups of machines you have access to, enabling you to easily build multi-architecture images with a single command. In this talk, we will highlight the challenges of multi-architecture builds and demonstrate how Podman farm addresses them, keeping performance and usability in mind.

Container images that run seamlessly across different architectures ensure consistency, reduce complexity, and accelerate the development cycle. This session will empower attendees to develop on one architecture and deploy confidently on another.

Noisy Neighbor Detection: A New OSS Collector - Jonathan Perry, Unvariance

Tuesday June 24, 2025 3:05pm - 3:45pm MDT

Bluebird Ballroom 2G

Why do some requests take so much longer than others? A major contributor, memory-related contention between containers, was shown to increase latency by 4-13x. It can be triggered by garbage collection, and existing observability cannot even detect it! Current collectors just show high CPU utilization, and the standard mitigation is to scale out and run at low utilization: expensive, and does not solve the response time problem.

We set out to build a new detector, but found that measuring every few seconds (current practice for collectors) is inadequate. Servers quickly jump between intense resource competition and under-utilization, so averaging over seconds does not show any contention. We needed measurements at millisecond frequency.

This session first examines real-world patterns that trigger interference and surveys methods for detecting memory interference, including findings from Google, Alibaba, and Meta's production environments. We'll then discuss the design of the OSS collector, and how it combines CPU performance counters, eBPF and high-resolution timers to identify noisy neighbors. We close with future directions and opportunities to get involved.

Unveiling Arm Confidential Computing Architecture Software Stack - Kevin Zhao, Linaro

Tuesday June 24, 2025 4:20pm - 5:00pm MDT

Bluebird Ballroom 2G

As confidential virtual machines become mainstream in confidential computing, the Arm Confidential Computing Architecture (CCA) was introduced as a key innovation of Arm v9 in 2021. Linaro has been deeply involved in integrating CCA into open-source projects over the past years.
In this presentation, we'll share the progress of our open-source enablement efforts. This includes the current status of fundamental software support and the next-stage plan for projects such as TF - A, Kernel, and Qemu. We'll also talk about container runtime adoption in Kata containers and Confidential containers. For instance, we'll detail the work on supporting CCA in Kata container runtimes with Qemu backend, like in kata-deploy. The support for guest-components and Trustee in Confidential containers will be covered too.
Remote attestation is another crucial aspect that can't be overlooked. To reduce solution fragmentation in open-source projects for production, Arm and Linaro are collaborating on an end-to-end experimental attestation platform using Veraison project components. We'll present a case study from the Confidential Containers project to show the practical adoption of these technologies.

FoundationDB, the Black Knight - Peter Boros, Tigris Data

Wednesday June 25, 2025 11:55am - 12:35pm MDT

Bluebird Ballroom 2G

Monty Python’s Black Knight is the opponent that couldn’t lose. Even after all of his limbs were cut off, he offered a draw: “it’s just a scratch.”

FoundationDB (FDB) is a distributed transactional key-value store that is very difficult to defeat just like the Black Knight. Open-sourced in 2018 after an acquisition by Apple, FDB was designed to be a common layer: almost all databases have a backing key-value store. Many have built on top of it including Snowflake, Adobe, & Datadog.

FDB got it right: transactions, distributed by default, and extreme reliability. Kyle Kingsbury (aphyr) the author of Jepsen series on distributed systems correctness, said: "haven't tested foundation in part because their testing appears to be waaaay more rigorous than mine."

We demo a live FDB cluster and try to disrupt its operations. Our attempts are informed by real world experience supporting a metadata service for billions of objects globally.

When we finally succeed, we show how backups and disaster recovery resurrect FDB. We’ll learn about highly resilient design patterns and operations. We have battle scars, and want to help others!

How To Put Swift in a Box: Container Images From Scratch With Swift Container Plugin - Euan Harris, Apple, Inc.

Wednesday June 25, 2025 3:05pm - 3:45pm MDT

Bluebird Ballroom 2G

Containers have changed how we build and run services. The days of FTPing a binary up to a server are gone, because our platforms expect to run containers. We build container images at every stage of development, whenever we want to test our services, and when we deploy them.

If container images are what we need, could our development tools help us build them? Yes, they can! In this talk, we'll take a container image apart, see what makes it tick, then put it back together again from first principles - all using Swift!

Swift is a high performance, memory-safe language which is ideal for server-side development. We will:

* download a container image, take it apart by hand and explore what’s inside;
* cross-compile a Swift service effortlessly to different Linux distributions, on x86 or ARM, statically or dynamically linked, from development environments on macOS or Linux;
* use Swift's pluggable build system to produce container images efficiently and automatically for every build;
* test the image.

Containers are a universal building block of modern services. Even if you're not yet using Swift, these ideas and principles also underpin your current build and deployment workflow.

Beyond Parent-Child: Enhancing Context Propagation With Span Links in Complex Distributed Systems - Haardik Dharma, NYU & Ekansh Gupta, SigNoz

Wednesday June 25, 2025 4:20pm - 5:00pm MDT

Bluebird Ballroom 2G

Context propagation is the cornerstone of observability in distributed systems, but traditional approaches often falter in non-linear workflows like message queues, event-driven architectures, state transitions, or shared resources. Span links powered by OpenTelemetry, bridge this gap by enabling connections between spans across unrelated execution contexts.

This session explores a practical use case where span links augment context propagation in an event-driven microservices system. We'll demonstrate how to track a single user's transaction across services that communicate asynchronously. Using tools like OpenTelemetry and compatible backends, we'll show how span links resolve visibility challenges, uncover hidden latencies, and maintain trace continuity even when the standard parent-child relationships break.
