You may have a customer with multiple different statutory legal compliance criteria and you may also have a customer with highly specific contractual hosting & data sovereignty NFRs. The latter often comes from the sales guy abandoning the normal contract template on any fear of losing their commission and promising any physical hosting model that the customer could imagine. The sales guy has not brushed up on his data sovereignty & EU safe harbour law and the customer is nervous about externalising any data. So it’s no surprise that you the architect are left to figure out this mess while maintaining some sanity by not spawning stovepipe after stovepipe in any customer territory.
If this keeps happening in your company then no TOGAF enterprise continuum will help you find and train a sales team led organisation on the variances of data sovereignty & safe harbour regulation.
