# elasticache ## Description Amazon ElastiCache is a web service that makes it easier to set up, operate, and scale a distributed cache in the cloud. With ElastiCache, customers get all of the benefits of a high-performance, in-memory cache with less of the administrative burden involved in launching and managing a distributed cache. The service makes setup, scaling, and cluster failure handling much simpler than in a self-managed cache deployment. In addition, through integration with Amazon CloudWatch, customers get enhanced visibility into the key performance statistics associated with their cache and can receive alarms if a part of their cache runs hot. ## Available Commands * [add-tags-to-resource](add-tags-to-resource.md) * [authorize-cache-security-group-ingress](authorize-cache-security-group-ingress.md) * [batch-apply-update-action](batch-apply-update-action.md) * [batch-stop-update-action](batch-stop-update-action.md) * [complete-migration](complete-migration.md) * [copy-serverless-cache-snapshot](copy-serverless-cache-snapshot.md) * [copy-snapshot](copy-snapshot.md) * [create-cache-cluster](create-cache-cluster.md) * [create-cache-parameter-group](create-cache-parameter-group.md) * [create-cache-security-group](create-cache-security-group.md) * [create-cache-subnet-group](create-cache-subnet-group.md) * [create-global-replication-group](create-global-replication-group.md) * [create-replication-group](create-replication-group.md) * [create-serverless-cache](create-serverless-cache.md) * [create-serverless-cache-snapshot](create-serverless-cache-snapshot.md) * [create-snapshot](create-snapshot.md) * [create-user](create-user.md) * [create-user-group](create-user-group.md) * [decrease-node-groups-in-global-replication-group](decrease-node-groups-in-global-replication-group.md) * [decrease-replica-count](decrease-replica-count.md) * [delete-cache-cluster](delete-cache-cluster.md) * [delete-cache-parameter-group](delete-cache-parameter-group.md) * [delete-cache-security-group](delete-cache-security-group.md) * [delete-cache-subnet-group](delete-cache-subnet-group.md) * [delete-global-replication-group](delete-global-replication-group.md) * [delete-replication-group](delete-replication-group.md) * [delete-serverless-cache](delete-serverless-cache.md) * [delete-serverless-cache-snapshot](delete-serverless-cache-snapshot.md) * [delete-snapshot](delete-snapshot.md) * [delete-user](delete-user.md) * [delete-user-group](delete-user-group.md) * [describe-cache-clusters](describe-cache-clusters.md) * [describe-cache-engine-versions](describe-cache-engine-versions.md) * [describe-cache-parameter-groups](describe-cache-parameter-groups.md) * [describe-cache-parameters](describe-cache-parameters.md) * [describe-cache-security-groups](describe-cache-security-groups.md) * [describe-cache-subnet-groups](describe-cache-subnet-groups.md) * [describe-engine-default-parameters](describe-engine-default-parameters.md) * [describe-events](describe-events.md) * [describe-global-replication-groups](describe-global-replication-groups.md) * [describe-replication-groups](describe-replication-groups.md) * [describe-reserved-cache-nodes](describe-reserved-cache-nodes.md) * [describe-reserved-cache-nodes-offerings](describe-reserved-cache-nodes-offerings.md) * [describe-serverless-cache-snapshots](describe-serverless-cache-snapshots.md) * [describe-serverless-caches](describe-serverless-caches.md) * [describe-service-updates](describe-service-updates.md) * [describe-snapshots](describe-snapshots.md) * [describe-update-actions](describe-update-actions.md) * [describe-user-groups](describe-user-groups.md) * [describe-users](describe-users.md) * [disassociate-global-replication-group](disassociate-global-replication-group.md) * [export-serverless-cache-snapshot](export-serverless-cache-snapshot.md) * [failover-global-replication-group](failover-global-replication-group.md) * [increase-node-groups-in-global-replication-group](increase-node-groups-in-global-replication-group.md) * [increase-replica-count](increase-replica-count.md) * [list-allowed-node-type-modifications](list-allowed-node-type-modifications.md) * [list-tags-for-resource](list-tags-for-resource.md) * [modify-cache-cluster](modify-cache-cluster.md) * [modify-cache-parameter-group](modify-cache-parameter-group.md) * [modify-cache-subnet-group](modify-cache-subnet-group.md) * [modify-global-replication-group](modify-global-replication-group.md) * [modify-replication-group](modify-replication-group.md) * [modify-replication-group-shard-configuration](modify-replication-group-shard-configuration.md) * [modify-serverless-cache](modify-serverless-cache.md) * [modify-user](modify-user.md) * [modify-user-group](modify-user-group.md) * [prepare-migration](prepare-migration.md) * [purchase-reserved-cache-nodes-offering](purchase-reserved-cache-nodes-offering.md) * [rebalance-slots-in-global-replication-group](rebalance-slots-in-global-replication-group.md) * [reboot-cache-cluster](reboot-cache-cluster.md) * [remove-tags-from-resource](remove-tags-from-resource.md) * [reset-cache-parameter-group](reset-cache-parameter-group.md) * [revoke-cache-security-group-ingress](revoke-cache-security-group-ingress.md) * [start-migration](start-migration.md) * [stop-migration](stop-migration.md) * [test-failover](test-failover.md) * [test-migration](test-migration.md) * [wait](wait/index.md)
