Deleting a cluster in ElastiCache - Amazon ElastiCache

Deleting a cluster in ElastiCache

As long as an ElastiCache cluster is in the available state, you are being charged for it, whether or not you are actively using it. To stop incurring charges, delete the cluster.

Warning

When you delete an ElastiCache cluster, your manual snapshots are retained. You can also create a final snapshot before the cluster is deleted. Automatic cache snapshots are not retained.

The following procedure deletes a single cluster from your deployment. To delete multiple clusters, repeat the procedure for each cluster that you want to delete. You do not need to wait for one cluster to finish deleting before starting the procedure to delete another cluster.

To delete a cluster

  1. Sign in to the AWS Management Console and open the Amazon ElastiCache console at https://console.aws.amazon.com/elasticache/.

  2. In the ElastiCache engine dashboard, choose the engine the cluster that you want to delete is running.

    A list of all clusters running that engine appears.

  3. To choose the cluster to delete, choose the cluster's name from the list of clusters.

    Important

    You can only delete one cluster at a time from the ElastiCache console. Choosing multiple clusters disables the delete operation.

  4. For Actions, choose Delete.

  5. In the Delete Cluster confirmation screen, choose Delete to delete the cluster, or choose Cancel to keep the cluster.

    If you chose Delete, the status of the cluster changes to deleting.

As soon as your cluster is no longer listed in the list of clusters, you stop incurring charges for it.

The following code deletes the ElastiCache cache cluster my-cluster.

aws elasticache delete-cache-cluster --cache-cluster-id my-cluster

The delete-cache-cluster CLI action only deletes one cache cluster. To delete multiple cache clusters, call delete-cache-cluster for each cache cluster that you want to delete. You do not need to wait for one cache cluster to finish deleting before deleting another.

For Linux, macOS, or Unix:

aws elasticache delete-cache-cluster \
    --cache-cluster-id my-cluster \
    --region us-east-2

For Windows:

aws elasticache delete-cache-cluster ^
    --cache-cluster-id my-cluster ^
    --region us-east-2

For more information, see the AWS CLI for ElastiCache topic delete-cache-cluster.

The following code deletes the cluster my-cluster.

https://elasticache.us-west-2.amazonaws.com/    
    ?Action=DeleteCacheCluster
    &CacheClusterId=my-cluster
    &Region us-east-2

The DeleteCacheCluster API operation only deletes one cache cluster. To delete multiple cache clusters, call DeleteCacheCluster for each cache cluster that you want to delete. You do not need to wait for one cache cluster to finish deleting before deleting another.
