You will find that the Stop RDS Instances and Start RDS Instances action views now have an option to target RDS Instances in Aurora Clusters. This is a huge opportunity for AWS cost optmisation and was a common request from many active members in our GorillaStack community.
Existing users will need to update their GorillaStack cross-account role. Start by navigating to the platforms view, and for the account you wish to target click the drop down and select Update Account Setup. Click the Get Started button and launch the change set. This will update the GorillaStack cross-account role to include the new required DB Cluster IAM permissions.
