Oracle on AWS - EBS mirroring
Question RAID and EBS Raid 1 - Does AWS EBS provide recovery from an EBS volume since the data is automatically mirrored by AWS?
Response: It depends on whether you want control over the recovery for mirroring. Using the built in mirroring means you do not control the mirroring and therefore when recovery happens. Other options include using Oracle Standby DB/DataGuard, GoldenGate or even EBS snapshots.
