2021-07-15: SCS R0 released

With great pleasure, we announce the Release 0 of Sovereign Cloud Stack.

While we officially only got the funding for our project a few days ago, we have already been able to do very useful work with the community that we were able to set up and which engaged in collaboratively developing software.

R0 is the culmination of more than a year of work, all of which can be found on github. SCS heavily relies on OSISM, so we actually are building on top of many years of work there. A lot of the SCS work got integrated back into it. SCS and OSISM of course build on top of thousands of person years of upstream communities' work. We are standing on the shoulders of giants.

We are really proud with what we achieved with our volunteer community! The automation for the lifecycle management of the (containerized) base infrastructure, the operations tooling, IAM and the IaaS layer is rock solid. The first two partners, betacloud and PlusServer are already using this for their productive clouds and more are in the pipeline. We have been monitoring the demonstrator (gx-scs) environment from PlusCloudOpen with openstack-health-monitor and have seen only one slowliness warning in weeks and not a single alarm. This is no small feat.

Thanks to anyone who contributed to this nice release!

R0 focuses on testbed deployments -- we want to make it easy for anyone to use SCS for testing, inspection, contribution, comparison, inspiration, ... at this stage. This in no way should discourage anyone from a production deployment on bare metal -- as mentioned we have two cloud providers already using it. Exploring testbed is typically the first stage though. Get in touch with us if you have made yourself familiar with SCS via testbed already and want to move to the next stage.

We have updated a lot of documents in the last days. Use our github Docs as entry point. There are specific release notes for R0. You can of course also find this from the "Get SCS" page from our web site.

The documents explain how to perform a testbed installation and also how to use the Technical Preview pieces such as the Kubernetes aaS pieces using the k8s-cluster-api. This will be one of the focus areas for R1 which we already plan for September. (Note: We'll have a 6 month release cycle going forward, though the reality is more continuous than this sounds.)

Let us know if you have questions or feedback. We like github issues and PRs, but will try to followup on email as well.
