AWS doesn't need to do anything innovative and the enterprises still come. Every product AWS sells has a similar offering from a competitor. But businesses stick with amazon because its all in one. They get bills from one company, trust their security with one company, ect. The only thing that matters to AWS is its reputation.
This works up to a point. I'm extremely familiar with AWS, but we simply _can't_ use it to train our models because it costs 2-3 times more than their competitors. All while requiring us to basically bring up all the infrastructure around maintaining the training cluster ourselves.
