Amazon Web Services, the Amazon store, retail and Amazon Publishing (KDP) are all various names used for one of the largest companies on the planet, started by Jeff Bezos. One of Mr. Bezo's many dreams was to provide books to the world and as part of that, in the mid-2000's, he bought a company called Createspace, and started providing Author and Publisher services to self-publishign authors. To this day, "KDP" is the largest self-publishing entity in the world. Some 7,000 (seven thousand) books per day are estimated to be published via KDP.
