Microsoft will invest another $700 million to expand its Iowa data center campus near Des Moines, marking the third major server farm for the state this year. Facebook recently announced a new data center in Altoona. The same day, Google said it would put another $400 million into its facility in Council Bluffs. Why Iowa? Aggressive tax incentives and a central location to bridge the distance between these companies' east and west coast server footprints."
