To stop a Redis ElastiCache cluster, you'll need to perform the following steps:
Navigate to the AWS Management Console and sign in.
Go to the Amazon ElastiCache service dashboard.
Locate your target Redis cluster under "ElastiCache Clusters."
Select the desired cluster.
Under the "Actions" menu, click on "Delete."
Choose whether you want to take a final backup before deleting the cluster by selecting "Create final snapshot?" (this is optional).
If you choose to create a final snapshot, provide a name for the snapshot.
Click "Delete" to confirm.
Please note that this action is irreversible, and it will permanently delete the selected Redis ElastiCache cluster along with its data. If you want to pause billing or temporarily stop the cluster, consider resizing it to a smaller instance type instead.
Here's an example using AWS CLI to delete the ElastiCache cluster without taking a snapshot:
