I feel that's where you keep missing the whole point. Somehow you're stuck on thinking that an expensive service is not a problem if you can waste time micromanaging and constantly monitoring expenditures to shave off a bit of cost from the invoice. Yet, somehow you don't register in your universe the fact that there are services out there that are both far cheaper and arguably better for this use case.

Therefore, why do you keep insisting on the idea of wasting time and effort micromanaging a deployment like pets to shave off some trimmings off a huge invoice if all you need to do to cut cost to a fraction of AWS's price tag is to.... switch vendor?
