OpenStack Version 24: Old Code and New Network Cards

OpenStack version 24 is ready. The new version of the open source software is called Xena and is now available for download. The Open Infrastructure Foundation, under whose patronage the software is being developed, emphasizes the size of the community behind the project: within 25 weeks, over 680 developers from over 125 different organizations have contributed almost 15,000 changes to the new version.

OpenStack is the basis for many public and internal cloud infrastructures. The software manages virtualization, networks and storage space and provides an API via which resources in an OpenStack environment can be ordered and managed.

In Germany, among others, Deutsche Telekom uses OpenStack as the basis for their public Open Telekom Cloud, as does the French hoster OVH. As an internal cloud platform, OpenStack runs at CERN. The Open Infrastructure Foundation has counted it once and comes up with 25,000,000 CPU cores that are operated with OpenStack. According to the organization, over 100 new environments have been added in the last 18 months.

The focus of the new version is less on new functions and more on shedding old braids. The Foundation speaks of “technical debts”: The old API version 2 in the block storage component Cinder has been thrown out. Cyborg, the component that takes care of all accelerator hardware (such as GPUs and ASICs), has received revised documentation. The Ansible integration has also been updated, now ansible-core 2.11 is used. Ansible can now also be used to control backups in OpenStacks backup and restore components (freezers).

Three OpenStack components had to be screwed on at the same time in order to integrate so-called SmartNICs, programmable network adapters: The compute component Nova, the accelerator component Cyborg and the network component Neutron will work together in the future to integrate such SmartNICs via PCI.

In view of the influx of wealthy and well-staffed companies, the Open Infrastructure Foundation looks positively into the future. More than 70 companies are already participating in the organization, most recently Microsoft also joined – although the company has so far gone its own way with its Azure cloud beyond OpenStack.
