Getting a product to be ready is fine but when you have a thousand users using your website at the same time going to be an issue
The basic reason we are into rails and product development is to that one day we can have a product that gets a million users at the same time
Should we be ready for that
So how do you start achitecting so tht scalling is done from the start.
By using different instances? One for database, one for application server? Is this approach the best?
