There's an awful lot of European whining about their lack of data sovereignty. But, despite the fact that the solution is stupidly simple - European company's or socialist governments build European hyperscalers - no one seems to be actually attempting to address the issue.
Chinese companies built Chinese hyperscalers early and quickly. Why doesn't Europe have it's own hyperscalers? It seems to me that OVH could possibly do it with OVHCloud, and there is Exoscale. The Europeans could switch to these and build them out. But, all I hear is whining about America bad.
So, unless the Europeans are going to actually try to do something about it I really don't want to hear them whining about it. And, for the record, switching to a file syncing NAS and Libre Office is nothing at all like building a hyperscaler.
That's probably what is at least in part going to happen, but it's not as easy as it seems.
China has no issue in pouring whatever state aid they want to whatever company they want and have a much greater motivation to not rely on US infrastructure due to the hostility between the countries. The EU or EU State Members on the other side cannot just decide to e.g. "go with Exoscale" or whatever domestic provider because state aid in the EU is pretty strictly regulated: other companies would have the opportunity to sue such decision as Governments are not supposed to "pick winners", at least in normal circumstances.
What would need to happen first is for the EU to designate hyperscalers as a strategic industry, thus allowing an exception to the "state aid" regulations. I think there is broad consensus that the reliance on US infrastructure is an issue, but until recent times not that it's something that needs to be addressed urgently due to the relatively friendly relationship between US and EU and the existence of alternative measures that can mitigate and control risk.
In more recent times that "friendly relationship" seem to have gone south, so it's perfectly possible the EU will accelerate towards a strategy of independence in the future including putting into practice a coordinated EU-level strategic industry designation and investments in domestic providers.
