Here's a suggestion for a big improvement: Pick apart the EC2 pricing page ( http://aws.amazon.com/ec2/pricing/ ) and find the URLs to the JSON (e.g. http://aws.amazon.com/ec2/pricing/ri-light-linux.json ) and build something that's totally dynamic.

Although the URLs and the formats aren't an official AWS API, I think it is pretty safe to count on them for an application like this.

Dear person that works at Amazon Web Services: please just build this for the community. ec2instances.info is a much better resource than the existing pricing page and the calculator is entirely too much for many uses/discussions.

thanks.

Or you can just ask me to make whatever changes you want...

Hi! Since we get to know that you are from Amazon and listening, will tell you about another situation, which will help me a great deal.

I don't think as of now, I can reserve a smaller configuration and if my need changes can just switch to a bigger reserved configuration. And the billing accommodates for the reserved price which I already paid for the smaller one.

(As a real example, I have medium running all the time, but don't reserve it thinking I may have to move to a large one in the near future. )

Or can I already do this, and it is my bad that I have not noticed? If yes, then please point me to the information about that.

If not, then can you take it as a feature request from me please.

Dear downvoter, I realized it was a bit off topic, that's why you sense a polite explanation in my first sentence itself.

And I am not completely off topic, as its partly an interface issue. I am not 100% sure, if such a thing is not possible. Also BTW, if you have asked a question in EC2 forums, then you will know that the answer often is late enough such that, by the time its there you would have already solved your problem.
