While signing up, almost all the cloud hosting providers(Amazon, Rackspace, etc) ask you to provide the amount of resources your site will consume so that they will bill you accordingly.<p>But the problem is how to measure the site usage upfront? If you are already running a site and migrating it to cloud, you would have some metrics in hand. But for a startup, how to estimate these metrics? Guesstimate?<p>Is there any tools that can be used to profile the app usage locally and then convert the metrics to cloud?
