If I understand this correctly, he’s not talking about a public cloud, but rather about Google-developed solutions for an air-gapped internal platform. Google have had several public job listings for “sovereign cloud” teams.
There are a few other companies that offer something similar in the enterprise space (e.g. VMware/Broadcom for the platform part), and a lot of them are from the US as well.
Would it be better to buy European? Certainly from an autonomy point of view. But that’s not the only factor in purchasing decisions and Google probably still have better access to talent.
