This is Amazon Web Services - their cloud hosting company, not the on-line retailer. This isn't about margin and turnover, its about governments spending money with suppliers who are paying low taxes, probably at a cost to conventional UK data centre services companies who do. Its really about time government procurement took this kind of stuff into account. i.e. UK jobs/taxes being a factor. Everyone else in the EU does it, under the guise of "critical national infrastructure".
