Why AWS and not Google? We had a bunch of AWS credits (thanks, folks!). I was very familiar with AWS. At my previous workplace at Qubole, we used to hammer EC2 and S3 and I was super-impressed by how robust AWS was. Finally, we knew AWS was launching in India soon (and they did). As an aside, AWS seems to be routing credits to early stage startups through events, shared spaces and investors and getting them hooked early — Google really needs to up its sales game.
