> I think there's another word missing: "data sovereignty". Depending on your business, your customers might need to keep user PII within their country.

That's assuming a single multi-tenant saas footprint.

There is absolutely nothing preventing you from standing up a footprint in each compliance region and customers are assigned to the region that satisfies their requirements for data location.

You get the benefit of less footprints to manage, while still meeting the requirements necessary to serve your customers.

And if you have a customer that absolutely must have isolated infrastructure, stand one up for them and pass along the increased cost associated.
