Let’s start by acknowledging the elephant in the room: The top three public cloud computing providers are all U.S.-based, so enterprises in the United States, and even in most other countries, are facing a natural U.S.-based monopoly on public cloud computing technology. So, there is a de facto “buy American” cloud provider policy due to the fact that you really can’t do anything else right now.
However, a few evolutions are taking place. First, the rise of cloud providers in China and some European countries has some thinking that commoditization of the public cloud space could open up the U.S. market to public cloud providers based outside the United States. Second, the globalization of enterprises means that many U.S.-based companies have more assets and employees outside of the United States than within.
