41 Directly Using Public Cloud as a DR Site On-Premises DR to Cloud Methodologies Backup-based DR RMAN Backup to Cloud (Low cost offsite storage with ondemand restores) Extend backups to instantiate database in the cloud for DR, DevOps Replication-based DR Standby in the Cloud using Data Guard Passive DR Standby in the Cloud using Active Data Guard Active DR Active / Active, Bi-directional replication using GoldenGate Cut over to Cloud when you want 41

42 Using Cloud at Customer for HA/DR Oracle Cloud in your Datacenter Cloud at Customer solves Cloud convenience within your firewall Network constraint to go over public network Data sovereignty or compliance requirements You want Oracle to take care of infrastructure Use Oracle Cloud for High Availability or Disaster Recovery Oracle Cloud Machine, Exadata Cloud at Customer Same capabilities as Oracle Cloud Active Data Guard replication from on-premises to Cloud at Customer Cut over to Cloud at Customer or Migrate to public cloud 42
