Apple also announced plans to invest $10 billion in its iCloud data centers across the U.S. over the next five years. Apple's existing data centers (that mostly house racks of servers, maintained by relatively few actual workers) are located in Maiden, North Carolina; Reno, Nevada; Prineville, Oregon; and Newark, California. The company plans to situate a new facility in Waukee, Iowa.
