OSF’s newly confirmed Open Infrastructure Projects celebrate progress in addressing infrastructure needs at scale, made possible by a global network of engaged developers and users embracing open source principles

DENVER — April 29, 2019 — Open Infrastructure Summit — The OpenStack Foundation Board of Directors announced today that former pilot projects Kata Containers and Zuul have been confirmed as top-level Open Infrastructure Projects of the OpenStack Foundation (OSF).

Confirmation conveys recognition of a project’s success in meeting the goals of the pilot process and a commitment from the OpenStack Foundation to continue supporting the project. When evaluating a pilot project for confirmation, the Board of Directors considers, among other factors, whether the project can demonstrate the following:

  • a strategic focus aligned with that of the OpenStack Foundation and its Open Infrastructure mission
  • well-defined governance procedures
  • a commitment to technical best practices and open collaboration, especially as conveyed by the principles of the Four Opens
  • an actively engaged ecosystem of developers and users that demonstrates a growing, healthy, and diverse community

“Kata Containers and Zuul are two exciting, highly useful software projects that are solving real-world problems for users by delivering production infrastructure with open source components,” said Allison Randal, board member, OpenStack Foundation. “In recognizing Kata Containers and Zuul as confirmed Open Infrastructure Projects, we are acknowledging the stability and maturity of these software projects and celebrating the growth and momentum of their respective collaborative communities.”   

“The confirmation of our first two pilot projects represents a significant milestone for the OpenStack Foundation as it pursues a broader mission of helping open source infrastructure communities collaborate and thrive,” added Alan Clark, chairman of the OSF Board of Directors. “Kata Containers and Zuul are the first pilot projects to be ‘incubated’ under the nurturing philosophies and culture of the OSF, which have been honed over the past 9 years as we have guided the OpenStack software project from its infancy to become one of the world’s largest and most engaged open source communities. It’s exciting to see this collective expertise applied to the benefit of new projects and to see our community expand its impact and innovation through collaboration.”  

Kata Containers: The Speed of Containers, the Security of VMs
Kata Containers enables a secure runtime underneath popular container technologies like Kubernetes and Docker, with lightweight virtual machines that feel and perform like containers, but provide stronger workload isolation using hardware virtualization technology as a second layer of defense.  

Kata Containers became an OSF pilot project in December 2017 and was confirmed on April 8, 2019. During this time,

  • The contributor base has expanded considerably, with 4,125 all-time commits from 116 authors representing more than 22 companies. Contributors include 99Cloud, Alibaba, Arm, Atlassian, Baidu, Branch, Cray, Dell, Ebay, Google, Huawei,, IBM, Intel, Interdynamix, Microsoft, Nvidia, Oracle, Orange, Red Hat, SUSE, Tencent, Vexxhost and ZTE.
  • AWS, Google, IBM, Microsoft, PackageCloud, Packet, SUSE and Vexxhost, an OpenStack-powered public cloud, have donated infrastructure resources to make sure that Kata Containers runs properly on different clouds.
  • The Kata Containers community has delivered several software releases and is actively collaborating and delivering cross-community integration with Containerd, Cri-O, Firecracker, Kubernetes, Open Container Initiative and Zun.

Zuul: Stop Merging Broken Code
Zuul uses project gating to automate continuous integration, delivery and deployment of interrelated software projects in a secure manner, while delivering sophisticated project gating, especially in scenarios involving multiple repositories with integrated deliverables. Zuul is built for a world where development, testing and deployment of applications and their dependencies are one continuous process.

Zuul became an OSF pilot project in May 2018 and was confirmed as an Open Infrastructure Project on April 28, 2019. During this period,

  • The community issued 15 releases, delivering features including support for AWS, OpenShift and multiple Ansible versions, speculative container execution, and the ability for jobs to control which child jobs run.
  • Zuul boasts a robust contributor base and user community, including the Ansible community, BMW, GoDaddy, GoodMoney, Leboncoin, OpenLab, OpenStack, Red Hat, SUSE, Tungsten Fabric, and the Wikimedia Foundation. 
  • Six case studies have been published highlighting how organizations like BMW, GoDaddy, Software Factory, Packet Host, leboncoin, and even the OSF run Zuul.
