Original article from Hibernate for cost savings for Advanced Cluster Management Provisioned Clusters with Subscriptions

OpenShift 4 has the ability to suspend and resume clusters on Cloud Providers. Red Hat Advanced Cluster Management extends this capability through its Cluster Lifecycle Management (Hive), where you can have a policy to hibernate the clusters to save the cost saving in non-working hours (ex. 16 hours in a day is 16/24 = 66% saving)
