Sovereign Cloud Stack (SCS) is a network of existing and future providers of standardized sovereign cloud and container infrastructure to join forces in defining, implementing and operating a fully open, federated, compatible platform. By joining forces, the platform can support a healthy ecosystem for service and application developers and strengthen the digitalization efforts in Europe without creating large risks to lose control over the technology and the data. Good starting points are the docs repository and the 'How to contribute page' page on the docs website. The SCS Standards are in the standards repository and are easiest to navigate on the aforementioned Docs Website.

You can follow us on Mastodon and LinkedIn or reach out to the community on Matrix.

Please contact the SCS security team at security[at]scs[dot]community to ask security questions or report security issues.

We publish security advisories to our low-volume announcement list announce[at]lists[dot]scs[dot]comunity. Please subscribe on here. Our security advisories are also published as blog posts.

Please see our How to contribute page.

We appreciate contribution to strategy and implementation. Please join our community — or just leave input on the github issues and PRs. We have a public taskboard. Have a look at our contributor guide. We also have defined a Code of Conduct to document the expected behavior of contributors and how we deal with cases where individuals fail to meet the expectation. With its direct leverage on the overall quality test automation and a high level of transparency about the status are very important to us. The status of our Continuous Integration can be viewed on the SCS Zuul and OSISM Zuul status pages. We are happy if you draw our attention to special topics with tickets here.

SCS is build on the shoulders of giants. Without the tremendous work of various open source communities SCS wouldn't be where it is today. What has started in the beginnings of the SCS funding project as "the reference implementation" already turned to the 'turn-key solution' in the last year of the funding project and has evolved to an ecosystem of Open Source Software.

We invite you to take a look at the following projects that play a role in the SCS landscape:

• ARKO - a monitoring stack, partially developed by dNation during the SCS funding project.
• ClusterStacks and the ClusterStackOperator
• OSISM the initial IaaS reference implementation as well as the various projects from OSISM, such as the OpenStack Flavor Manager and the OpenStack Image Manager
• uStack - uStack is a GitOps-based integration layer for OpenStack on Kubernetes using YAOOK, similar to OSISM with OpenStack Kolla-Ansible.
• Yaook - Yaook is a lifecycle management tool and distribution for OpenStack on top of Kubernetes.
