Kinetica in AWS is deployed as a CloudFormation stack and deleting the stack will remove all associated resources and costs.
To delete the stack through the AWS Console:
Sign into the AWS Console at:
Search for CloudFormation in the console search bar.
Choose the AWS Region where you originally deployed the stack (e.g., us-west-2).
Select the original stack you created (not the nested stacks), and then click Delete.
The process will also delete the nested stacks and will take approximately one hour to complete. At the end of the process, you should see that all of the resources have been successfully been removed.
