Amazon recently introduced a free tier for its cloud offering. I signed up for AWS and while signing up for the free tier of S3, i found thisAs part of AWS Free Usage Tier, you  can get started with Amazon S3 for  free. Upon sign-up, new AWS customers  receive 5 GB of Amazon S3 storage,  20,000 Get Requests, 2,000 Put Requests,  15GB of bandwidth in and  15GB of bandwidth out each month for  one year.source:aws.amazon.com , emphasis mine.20,000 GET requests & 2000 puts mean , 20,000 page views(max) and 2000 file uploads per month.Isn't that lower than what App Engine offers 43,200,000 requests per day.Am I missing some thing, please help.

YesGoogle Apps engine costs less. So if you can live with the restrictions (programming model!) of app engine, it is the by far more cost effective solution.
