You cannot stop an Elasticache cluster. Currently, there is a provision only to Delete it or Recreate one more. But you can do something which will give you a similar result as stopping an Elasticache cluster.
- Take a Snapshot of your cluster
- Delete your cluster
- Use the created snapshot to create a new cluster with the same data as the deleted one
When you create with the snapshot of a cluster, It will have the cluster id, region and the aws account id. So, when you create a cluster using the snapshot, your cluster will have the same endpoint.
