This page shows the options: http://aws.amazon.com/ec2/instance-types/ This the pricing: http://aws.amazon.com/ec2/pricing/ I guess the easiest thing to do is add some metrics, start small, and see where the beast bogs down? kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself."

To start with, use some program like apache bench (ab).

Generally from my experience with web servers 50-100 requests per second per CPU core is doable.

I believe the traditional approach to such questions is called "measurement"

Anyway, your cherished wysiwyg math editor is on the way, thx to jsMath. Thx for the reference! That library and its successor has a great author. And qooxdoo is brilliant, too. Add Lisp and Cells and I should soon rule the world. kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself." Macworld |
