Pinterest had 17.8 million monthly unique visitors as February came to a close

Among other things, the Pinterest pinboard uses Amazon's S3 object storage to keep the photos and videos that its millions of users have uploaded. Between August last year and February this year, Pinterest has grown its capacity on S3 by a factor of 10, and server capacity on the EC2 compute cloud is up by nearly a factor of three, according to Park, from about 75,000 instance-hours to around 220,000

The hourly costs are surprisingly , IMO, small ..they were $52.00 per hour to $15.00 per hour, and with ELB watched over by their own service, they have reached "max" hourly cost of $35.00 per hour..which at 17 million visitors per month is "interesting"..
