No. You're paying so much because (a) they make a lot of money ($20bn yearly profit) and (b) they have an extremely large headcount which are building the large number of services they provide.

Never heard of them running on other providers though.

Surely that would a problem for all of the compliance e.g. HIPAA, FIPS ?

Both A and B are true. But that doesn't preclude them from still charging a heavy premium over other providers in the market. Which is exactly what is happening, the raw COGS of operating a provider are dramatically lower than the prices they charge.
