OpenStack Ussuri release, OSF events, project updates and more


Spotlight on: OpenStack Ussuri 

Ussuri, the 21st release of OpenStack, includes improvements in core functionality, automation, cross-cell cold migration, containerized applications, and support for new use cases at multiple levels in the stack.

Thank you to the more than 1,000 contributors from more than 50 countries and 188 organizations that contributed to the OpenStack Ussuri release. With these metrics, OpenStack continues to be one of the top three open source projects in the world in terms of active contributions, along with the Linux kernel and Chromium.

Among the many enhancements contributors delivered in Ussuri, three highlights are:

  1. Ongoing improvements to the reliability of the core infrastructure layer
  2. Enhancements to security and encryption capabilities
  3. Extended versatility to deliver support for new and emerging use cases

This year, we are celebrating 10 years of the OpenStack project. Since the software pioneered the concept of open infrastructure ten years ago, it has rapidly become the open infrastructure-as-a-service standard. Recently, new workload demands like AI, ML, edge, and IoT have given rise to the project’s support for new chip architectures, automation at scale down to the bare metal, and integration with myriad open source components. Intelligent open infrastructure—the integration of open source components that are evolving to meet these demands—creates an infrastructure that is self-monitoring, self-replicating, and delivering a versatile set of use cases.

The Ussuri release reinforces what OpenStack is well known for—namely, rock-solid virtual machine, container, and bare metal performance at massive scale. At the same time, Ussuri delivers security improvements via Octavia and Kolla. And, it supports new and emerging use cases with improvements to projects like Zun and Cyborg. 

Users can now use Nova to launch server instances with accelerators managed by Cyborg

OpenStack: Open source software for creating private and public clouds

  • Ghanshyam Mann announced the completion of the Python 3 transition goal. It’s been a long journey since we started to introduce Python 3 support in 2013! OpenStack components and libraries are now Python3-only (except Swift and Storlets which will continue to support Python 2 in Ussuri).
  • Following the recent elections, the OpenStack Technical Committee selected Mohammed Naser as its chair for the Victoria cycle. It also confirmed the removal of the Congress and Tricircle projects in the Victoria release (scheduled for October 2020), and the merge of the LOCI team into the OpenStack-Helm team, due to commonality of scope.
  • Are you ready to take your cloud skills to another level? The updated Certified OpenStack Administrator (COA) exam can help you with that. Check out the OpenStack COA exam and become a Certified OpenStack Administrator

StarlingX: A fully featured cloud for the distributed edge

  • The nomination period for the upcoming TSC elections is starting next week! For details about the process please see the elections website
