Cost
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.
Note
The monthly cost was estimated for a quota size of 2,000, as of this revision. If more quotas are supported by Service Quotas for additional resource types, the quota size would increase and monthly estimated cost could be higher. The costs provided are estimates based on a 6-hour monitoring frequency.
The scalable costs (Amazon SQS and DynamoDB) increase with the number of accounts and Regions.

Note
We calculated cost per month with the following formula: [monthly fixed cost for a hub stack] + [monthly scalable cost for a hub stack] * [number of accounts] * [number of regions] + [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]
