The eighth release of the Sovereign Cloud Stack (SCS) has been published. With the update of the reference implementation, administrators can select the version of some central components. As an alternative to Ubuntu 24.04 LTS, it is also possible to run the cloud on the previous version Ubuntu 22.04 LTS. Administrators can also choose between Ceph Reef and Quincy and between OpenStack 2024.1 and 2024.2. In addition, the 20xx.2 release can be skipped in SCS when upgrading OpenStack, so that a direct switch from 2024.1 to 2025.1 is possible, for example.
SCS Cluster Stacks supports multi-stage add-ons
SCS Release 8 also uses the latest versions of Kubernetes and the associated cluster API. The Cluster Stack Provider for OpenStack is no longer part of the reference implementation. Instead, the OpenStack Provider now includes the OpenStack Resource Controller. In addition, the SCS Cluster Stacks now support multi-stage add-ons. In this way, the developers want to ensure that the various components are updated in the correct order during Kubernetes upgrades and that no cluster downtime occurs.
In the eighth release of SCS, administrators can also select between different Kubernetes versions and upgrade their clusters independently. The update also includes new features in the operating tools. The container registry Harbor and container monitoring have been updated to the latest version. Both applications have already been in productive use for several weeks. All changes in the eighth edition of the SCS can be found in the project's release notes.
Between 2021 and 2024, the Federal Ministry for Economic Affairs and Energy funded the SCS project with around 15 million euros. After the funding ended, around 20 companies joined forces to continue the project together with the Open Source Business Alliance and further develop the reference implementation. SCS is also contributing to the European cloud platform Gaia-X and the GovStack initiative, which aims to enable governments to develop sovereign cloud services with a modular system.
