AWS was not implemented by an offshore team. The link you pasted implies that EC2 was implemented by an offshore team - which is not correct either. EC2 had two teams, one of which was in Cape Town. The other team was in Seattle - and larger than the one in Cape Town. The rest of AWS at the time (2007) consisted of S3, SQS, DevPay, CDN, SimpleDB (AWS' own DB implementation at the time) etc... These teams were all in Seattle (in the red brick building by I5).
