Cost

You are responsible for the cost of the AWS services used while running this solution. As of September 2022, the cost for running this solution with the default settings in the Default AWS Region (US East (N. Virginia) is approximately $555.83 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. We recommend reviewing Amazon Kendra pricing and Amazon Connect pricing, if you choose to integrate these services.

We recommend creating a budget through AWS Cost Explorer to help manage costs. Prices are subject to change. For full details, refer to the pricing web page for each AWS service used in this solution.
