Health data can reside within your hospital's network. Government data within your government's network. Etc,...
I think the point is that your doctor or civil servant or local sushi shop shouldn't have to reach to AWS/GCP/Oracle each time they want to look up an MRI or building permit or loyalty points card status.
The data should reside exactly where they’re needed and nowhere else. For the UK NHS that’s probably in a UK data centre run by a UK company. Not AWS.
The fundamental problem with SaaS and pure server side applications is we do not know where the data are. With local first we can verify data locality.
Unfortunately the American companies are using their monopolies to price out everyone else. You're now in a situation where it's harder and harder to find people in the UK that can operate data centre services at the speed and quality of the cloud providers. The UK/EU needs it's own GCP/AWS/Azure alternatives. Unfortunately there's not really anyone close.
Sure! I'm just talking about data residence. They can transfer data over the internet (or some inter-hospital network) no problem. It's just a matter of "local-first".
