Sponsored Session: Following the Golden Image Road: Best Practices and Pitfalls - Natalie Somersall, Chainguard
Tuesday June 24, 2025 11:55am - 12:35pm MDT
The rise and increased prevalence of software supply chain attacks, the strengthened security requirements of compliance frameworks, and the speed and complexity of automated software development and build processes have all driven the need for open source standardization, often called Golden Image or Base Image programs.

But while DevOps and security teams recognize how critical open source standardization is, few feel comfortable tackling a large and fragmented challenge like open source software delivery, especially across diverse and disparate developer needs.

Join Chainguard’s Natalie Somersall to learn about best practices and common pitfalls that you
should be on the lookout for when taking on a golden image program.

Audience members will walk away with a clear understanding of the right change management milestones to keep in mind, the critical implementation criteria, and the most compelling use cases to make developers more productive and deliver secure open source software from the
start.

Sponsored Panel Discussion: Architecting for the Long Haul: Technical Strategies for Sustainable Open-Source Support Models - Andrew Sullivan & Mark Asselstine, Wind River; Megan Knight, Arm; Katherine Druckman, Intel
Tuesday June 24, 2025 2:10pm - 2:50pm MDT
Open-source project contributors bring diverse motivations to their work—from the joy of building something meaningful to the pride of seeing their code actively used. Users of open-source software look to benefit from projects that provide compelling solutions, drive standardization, and have supportive communities.
This raises a critical question: How can open-source projects remain sustainable over time while meeting the diverse support needs of users?
In this panel discussion, open-source advocates and representatives from commercial organizations, both contributors and users of open-source software, will explore the complex dynamics of long-term sustainability in the open-source ecosystem. The conversation will address:
  • Sustainable support models in open-source communities
  • Aligning commercial and community interests
  • Success stories and lessons learned the hard way
  • Funding strategies: who pays, and how?
Join us to gain valuable insights from multiple perspectives and take part in a live Q&A session to have your questions answered by the experts.

Tuesday June 24, 2025 3:05pm - 3:45pm MDT
 In 2014 the Angular team at Google decided to deprecate AngularJS while the replacement wouldn't ready for another 2 years. 10 years later with a lot more hindsight, Stephen will share the lessons learned so that you can more successfully drive adoption, evolve your ecosystem, stay fresh and relevant, and even support the developers you leave behind.

Sponsored Session: Unifying Observability at DoorDash using Open Standards - Owen Zhang, DoorDash & Victor Soares, Chronosphere
Tuesday June 24, 2025 4:20pm - 5:00pm MDT
If mobile observability leaves you hungry for answers, learn how DoorDash cooked up a scalable, open-source recipe — delivering OpenTelemetry metrics backed by community collaboration to bring it to everyone’s table.
While backend services benefit from mature observability tooling, mobile has long been underserved. DoorDash engineers faced this firsthand: messy metric semantics, inconsistent formats, and unclear signals that blurred real issues with telemetry artifacts.
Before, mobile health metrics were generated with an expensive, ETL-like system that was never meant for real-time monitoring and alerting. The team migrated to a unified, cloud-native observability platform powered by OpenTelemetry and Chronosphere, bringing mobile telemetry up to par with backend systems. After migrating, DoorDash achieved significant improvements, including reduced data volume, decreased costs, and improved alert reliability.

This talk shares lessons from that journey and provides practical guidance for anyone integrating OpenTelemetry metrics with Prometheus, especially when delta metrics are involved.
