Amazon Web Services Price History?

Is there a site that offers price history for various Amazon Web Services such as EC2, Cloudfront, etc? Something like on 1/1/2009 a small on demand ec2 instance in the US East region cost $x.xxxx, on 1/1/2010 it cost $x.xxxx.

I would like to be able to forecast that if something like a small on demand EC开发者_StackOverflow2 instance costs $0.085 per hour today that it will likely half in cost to $0.043 per hour a year from now. Similarly if I have 10GB of files in S3 storage how will the cost be affected over a similar span of time? I can only imagine, that like all technology, the cost will go down.

I cannot seem to find any pricing information aside from this site which lists only the fluctuating cost of spot instances.

And this statement made by Amazon on 8/20/2009 claiming that reserved instance pricing had been reduced by 30%.

http://aws.amazon.com/about-aws/whats-new/2009/08/20/New-Lower-Prices-for-Amazon-EC2-Reserved-Instances/

Any suggestions?

For anyone else looking for this, entering the following phrase in Google should be helpful for changes up through around 2014:

site:aws.typepad.com pricing s3

For more recent changes,

site:aws.amazon.com/blogs/aws/ pricing s3

This searches the AWS blog for pricing s3 which brings up most of their previous price change announcements.

You could also use the "Price Reduction" tag on the AWS Blog : http://aws.typepad.com/aws/price-reduction/

You could always go through archive.org and check the prices on different dates. They have the prices going back to the beta here.

This site offers EC2 spot price histories accessible via an API:

I hope this helps.
