Microsoft and Amazon struck a brilliant partnership to take on Google in the next big thing for cloud computing (GOOG, AMZN, MSFT)

Microsoft and Amazon announced a surprise partnership on Thursday in which they were jointly releasing for free a new software tool for developers called Gluon.
Gluon makes it easier for developers to build AI/machine learning systems, aka apps that can learn. 
But there's another, more important reason this partnership is interesting: it challenges Google in its one big area of dominance.
Microsoft and Amazon have joined forces to help spread artificial intelligence across apps.
