I run a European cloud service, 80% of our customers are basically looking for a European alternative to the big clouds. The market is huge and in my opinion underserved. What makes it very exciting is that there not too much innovation required to compete
Open Telekom Cloud has at least a great part of the functionality you expect when talking about a cloud provider: VMs (even GPU ones), VPCs, managed databases, block storage, Logging, IAM, API Gateway, Container Engine etc. https://www.open-telekom-cloud.com/
Deutsche Telekom used Huaweis OpenStack implementation.
I haven't found any information that this changed, so I assume it is still running completely on Huawei. At least they made sure that they still get chips from the US despite sanctions. ;-)
