Cost
You are responsible for the cost of the AWS services used while
running the Quota Monitor for AWS solution. We recommend creating a budget through
AWS Cost Explorer
The following tables provide a sample cost breakdown for deploying this solution with the default parameters in the US East (N. Virginia) Region for one month. There are additional minimal costs for a hub stack and a spoke stack.
Monthly cost by number of accounts
| Deployment size | Number of accounts | Number of AWS Regions | Cost per month [USD] |
|---|---|---|---|
| Small | 10 | 25 | $12.25 + 10*$0.01 + 250*0.16 = $52.35 |
| Medium | 100 | 25 | $12.25 + 100*$0.01 + 2,500*0.16 = $413.25 |
| Large | 1000 | 25 | $12.25 + 1,000*$0.01 + 25,000*0.16 = $4,022.25 |
Note
We calculated cost per month with the following formula:
[monthly cost for a hub stack]
+ [monthly cost for a Trusted Advisor spoke stack] * [number of accounts]
+ [monthly cost for a Service Quotas spoke stack] * [number of accounts] * [number of Regions]
