Spotlight on the Open Infrastructure Summit Denver

The global community gathered recently in Denver for the Open Infrastructure Summit followed by the Project Teams Gathering (PTG). This was the first edition under the new name, which was changed to better reflect the diversity of open-source communities collaborating at the Summit. With the co-location of the PTG, the week had more collaborative sessions than ever and attendees had the opportunity to collaborate throughout the week with presentations, workshops, and collaborative sessions covering the development, integration and deployment of more than 30 open-source projects.

The theme of the week was “Collaboration without Boundaries,” a call to the community shared by Jonathan Bryce in his Monday morning keynote. Collaboration was exemplified throughout the week from the developers, operators and vendors attending the event:

  • Developers from the Kata Containers and Firecracker projects highlighted the progress around community collaboration and project integration. They also discussed Rust-VMM, a cross-project collaborative initiative to develop container-specific hypervisors.
  • Operators from Baidu, Blizzard Entertainment, CERN, Box, Adobe Advertising Cloud and more presented their open infrastructure use cases, highlighting the integration of multiple technologies including Ceph, Kata Containers, Kubernetes, and OpenStack among 30+ other projects.
  • 5G was front and center at the Denver Summit. In a demonstration of open collaboration, Ericsson partnered with AT&T to host a 5G Lounge where attendees could test the latency of network speeds while playing a virtual reality game, Strike a Light. Users like China Mobile and AT&T presented about their 5G deployments. At AT&T, 5G is powered by an Airship-based containerized OpenStack cloud.
  • The NIST Public Working Group on Federated Cloud and The Open Research Cloud Alliance discussed possible federation deployment and governance models that embody the key concepts and design principles being developed in the NIST/IEEE Joint working group and ORCA. They want to encourage developers, users and cloud operators to provide use cases and feedback as they move forward in these efforts.

OpenStack Foundation news

  • At the Open Infrastructure Summit, the OpenStack Board of Directors confirmed Zuul as a top-level Open Infrastructure project, joining OpenStack and recently confirmed Kata Containers.
  • The OSF launched the OpenStack Ironic Bare Metal Program in Denver, highlighting the commercial ecosystem for Ironic, at-scale deployments of Ironic, and evolution of OpenStack beyond virtual machines. Case studies by CERN and Platform9 were published along with the announcement

OpenStack Foundation project news


  • The Airship team delivered its first release at the Open Infrastructure Summit Denver. Airship 1.0 delivers a wide range of enhancements to security, resiliency, continuous integration and documentation, as well as upgrades to the platform, deployment and tooling features.

Kata Containers

  • The community delivered several talks during the Open Infrastructure Summit in Denver that you can check out among the videos from the event.
  • Kata Containers continues to provide improvements around performance, stability and security.  Expected this week, the 1.7 release of Kata Containers includes experimental support for virtio-fs in the NEMU VMM. For workloads which require host to guest sharing, virtio-fs provides improved performance and compatibility compared to 9pfs. This release adjusts the guest kernel in order to facilitate Docker-in-Kata use cases, and adds support for the latest version of Firecracker.



  • There were five sessions dedicated to the project at the Open Infrastructure Summit in Denver, check out the videos here.
  • Participants packed room for a hands-on workshop to try out the StarlingX platform on  hardware donated by If you missed this one, keep an eye out for similar workshops at community upcoming industry events.
  • The team had great discussions during Forum sessions as well as at the PTG to deep dive into the details of processes, testing and roadmap planning for the upcoming two releases.


  • The community delivered several talks during the Open Infrastructure Summit in Denver that you can check out among the videos from the event.
  • Zuul 3.8.1 was released, fixing a memory leak introduced in the previous 3.8.0 release. Users should update to at least 3.8.0 to fix this bug. More info can be found in the release notes.
  • Nodepool 3.6.0 was released. This release improves API rate limiting against OpenStack clouds and statsd metric gathering performed by the builder process. Find more info in the release notes.
