 You can configure Elasticsearch to make copies of the shards, called _replicas_. Elasticsearch also spreads these replicas across
 the Elasticsearch nodes. The *ClusterLogging* Custom Resource allows you to specify the replication policy in the Custom Resource Definition (CRD) to provide data redundancy and resilience to failure.

 The Cluster Logging Operator and companion Elasticsearch Operator ensure that each Elasticsearch node is deployed using a unique Deployment that includes its own storage volume.
 You can use a Cluster Logging Custom Resource (CR) to increase the number of Elasticsearch nodes.
