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
