Billing in Stratus is designed to be simple and predictable. Although Mojo Stratus is built on top of many Amazon services, which each have their own individual pricing schemes, our pricing is reduced to only three values on our autoscaling plans.
A regular monthly payment of a base price depending on the plan.
A small charge per session as measured by Google Analytics is added for sessions in excess of the selected plan. Sessions are not charged on development instances or RBP plans. Production instance session charging begins when your site goes live. Your site is counted as going live when it uses a domain other than its MageMojo provided temporary domain name.
We sample storage used once per day. Storage use includes the primary instance, all associated dev instances and backups. At the end of the billing cycle we average the amount, then subtract your included storage for a final amount.
Sum of daily storage / # of days in billing cycle
2993 / 31 = 96.548 (97G)
Subtract included storage (pro in this example)
97 - 75 = 22G
Multiply times rate (pro in this example)
22 x 0.47 = $10.34
