SEATTLE: DefinedCrowd, a Seattle software startup, had a choice to make when it was developing its first product last year: build on the cloud-computing foundation offered by the dominant Amazon, or Microsoft's upstart competitor?
For founder Daniela Braga, the competing services seemed about even in terms of features. On price, Amazon's tools were a bit cheaper than Microsoft's. And more developers were comfortable working with Amazon Web Services, or AWS, the cloud-computing pioneer and now the market's largest player.
