The OpenStack community has released a new version: Zed can collect logs centrally, gets a fresh frontend and supports new hardware.


The 26th edition of the open source cloud software OpenStack is ready. It’s called Zed, fulfills numerous wishes from the community and is now available for download. The Open Infrastructure Foundation, which oversees OpenStack, also has a new user record to report.


According to developer figures, OpenStack is already running on over 40 million cores, and 180 public cloud data centers use the software as the foundation for their cloud infrastructure. Just a year ago, the mark of 25 million cores was cracked. In Germany, among others, Deutsche Telekom uses OpenStack for its public Open Telekom Cloud, in France the hoster OVH.

15,500 changes from 710 developers from over 140 organizations have flowed into Version Zed, the development of the semi-annual release took 27 weeks – it also marks the end of an epoch: In March 2023 the next semi-annual version will be released, whose name starts with A again and is called Antilope becomes. With this, OpenStack is also changing its release cycle: If you want to continue using new functions every six months in the future, you will continue to install the spring version (called SLURP) and the autumn version. If you want to skip the features in the fall, update directly from one spring version to the next.

Zed learned something new by supporting additional hardware. The Cinder block storage module now talks to Dell PowerStore NFS and NVMe-TCP and Yadro Tatlin Unified iSCSI systems.

The accelerator module Cyborg (previously called Nomad) and special hardware such as ASICs, GPUs and FPGAs connects learns support for FPGA hardware from Xilinx. Also new is support for Multi-Instance GPU (MIG) based on NVIDIA Ampere, a technique for splitting GPUs.

As a new project, OpenStack Venus appears together with Zed. The software collects logs from OpenStack instances and is primarily aimed at operators of large environments who need a better overview of their environment. Venus compiles reports and visualizations for this and can generate alarms in the event of problems.

The OpenStack Skyline project provides a new web interface based on React. It has not yet been released for productive use, according to the developers it is still a developing pre-release. In order for such up-and-coming projects from the environment to continue to be part of OpenStack in the future, the technical committee has established guidelines for identifying such projects.

Anyone who wants to help shape OpenStack will have the opportunity to discuss further development at a virtual event organized by the Open Infrastructure Foundation in mid-October. At the “OpenInfra Project Teams Gathering”, which will take place from October 17th to 21st, 2022, the steps for the next six months. Participation is free.
