Even apart from the large infrastructure cost for a geographically distributed and reliable network, a lot of the value of AWS/GC/Azure comes from the many built in services that completely change the ops workload. Building out those services is a monumental task requiring loads of experts in their respective fields (databases, storage, networking, etc). I see this as at least as much of a hurdle as the capital expenditure.
