To uninstall CloudyCluster take the following steps:
Delete or terminate any HPC Environments you have running by selecting the trash can icon in the upper right corner. This will delete the whole cluster.
All data associated with this cluster will be removed, including any EFS, S3, or Working Storage. Make sure you back up any needed data to a different location.
Proceed to the Administration tab and select "Delete CloudyCluster Instance and Database." This will remove all users, collaborations and anything associated with CloudyCluster. You will not be able to recover from this.
Select "Delete" and the database will be removed and instance shut down and terminated. The web UI will become unavailable.
If you launched through the AWS Marketplace, go to the Cloud Formation console to remove the Stack associated with this CloudyCluster instance.
Select the Stack and choose "Delete Stack." This will remove the IAM role and Policy initially created by the template.
