elastic dynamodb #14

one benefit that you buy into when switching to "serverless" cloud architecture is elasticity i.e. just show us the money, and we scale your infrastructure anyway you need. Wrong!

DynamoDB read/write capacity can only be scaled manually, and you pay for the idle capacity. The mismatch should be corrected by using the capacity as a maximum (i.e. I don't want to pay more than X USD for this dynamodb table being used this month), and you only pay for the used capacity.
