Amazon Web Services Price History?

Question

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 EC2 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?

Answer 1

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

I hope this helps.

Answer 2

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.

Answer 3

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

Answer 4

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