Cost

You are responsible for the cost of the AWS services used while running this solution. As of this latest revision, the cost for running the default basic implementation of this solution in the US East (N. Virginia) Region is approximately $547.33 per month.

Note

Amazon Kendra and Amazon Connect are not part of the default solution implementation, but the solution does provide the capability to integrate with them. Because the solution does not create resources for Amazon Kendra or Amazon Connect automatically, they are not included in the example cost table. If you intend to integrate Amazon Kendra and Amazon Connect, review the Amazon Kendra pricing and Amazon Connect pricing to adjust your cost estimate accordingly.

We recommend creating a budget through AWS Cost Explorer to help manage costs. Prices are subject to change. For full details, see the pricing webpage for each AWS service used in this solution. For additional information, see Creating a cost budget in the AWS Cost Management User Guide.
