Amazon to Battle Google With New Cloud Service for AI Software - Bloomberg

"Amazon’s new service will let businesses run different frameworks on its computers, including those created by rivals such as Google, which introduced one called TensorFlow last year, according to the people familiar with the situation.
The service will use a new type of rentable computer from Amazon that has eight graphical processing units from Nvidia Corp., up from four available on Amazon computers today, the people said. GPUs are a common type of semiconductor widely used to run AI programs. The more GPUs, the faster Amazon’s computers can run AI software and crunch related data."
