I am getting ready to sign up with Rackspace to host an application I'm about to release. It's an online workflow tool (www.worldwideworkbench.com
) that mainly consists of a php/mysql app that people use to manage projects.
So, it's mainly people looking at forms, filling in or reading data, then clicking to the next similar page. Not unlike a forum in that the site will be very text heavy, and almost all images will be cached by the browser early on, with the exception of the occasional uploaded image.
My question is: How do I determine how much bandwidth I need? Rackspace is a killer once you exceed the 30g limit, and I'm really not sure how this kind of thing goes.
I can guess, but is there any METHOD or metrics for this? It would be great to know how much THIS site uses, for example. If anyone has any busy websites that I can use for comparison, that would be really helpful.
