Lambda, SNS, SQS, and CloudWatch usage mainly contribute to infrastructure cost. In
AWS Cost
Explorer, you can sort out those resource costs by using the FSS-Storage-Stack and
FSS-Scanner-Stack tags, which have been tagged on the "Name" key along with All-in-One
CloudFormation template deployment. If there are scanner deployments, storage stack
deployments,
or custom configurations like post-scan action lambda, you can include them in the
estimation
dashboard by creating a "Name" tag.

The cost correlates with the number of scanned files. Here are sample statistics for
one
company's AWS usage for File Storage Security.
