To be honest, this is all the domain of your AWS service advisor. At any type of scale(eg, when you move to invoiced billing because CC billing would be absurd), you should be overwhelmed by phone calls from that individual. While half of their job is to upsell you, the other half is to help you save costs to garner goodwill(and your future business).

If you've been dodging these calls in the past, it might be worth picking up the phone.
