This service isn't for you. At least not for now. This service right now is for already big companies, probably non-IT ones, looking to outsource their datacenter needs, in a GDPR compliant manner, and looking to do more "digital" in the future. These kinds of players do not look for one-click solutions, they are looking for actual people to discuss their individual requirements.
Maybe latter on this thing will do AWS-style provisioning and services, but right now that doesn't even seem to be a current goal.

I see some media claim their are that, but it doesn't look like they themselves make that claim.
