Open Source Summit North America 2025

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.

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.

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.

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.

This session explores the integration of eBPF and OpenTelemetry (OTel) for achieving unparalleled observability and performance in 5G networks. By leveraging the K8s Operator framework, we demonstrate the Kubernetes-native deployment of advanced observability tools, including the bpfman stack for managing eBPF programs and the OpenTelemetry Operator for scalable telemetry pipelines. Participants will gain actionable insights into optimizing 5G Cloud Native Network Functions (CNFs) through precise observability, robust performance metrics, and real-time diagnostics, while ensuring security and multi-tenancy.
