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.
