Yorizon Cloud is a European IaaS cloud for companies and public organisations that need virtual servers, networks and storage, including for compute- and data-intensive workloads such as AI. The service runs on OpenStack with a KVM hypervisor and, according to the provider, offers platform options compatible with the Sovereign Cloud Stack. You manage resources through a central portal with a dashboard, cost overview and reporting, or through the OpenStack API and a Terraform provider. Capacity scales from a single virtual server to a dedicated cluster.
The provider is Yorizon GmbH & Co. KG in Berlin, Germany, with a second postal address in Vienna. According to its website, the cloud is operated in Germany, on decentralised edge data centres (YEXIO) in Germany and Austria, so data stays in the EU. The website does not say who owns Yorizon; ask the provider if the ownership structure matters for your assessment. The service is consumed as a cloud service, not as software you install yourself.
