Business leaders expect two things from IT: keep mission-critical applications available and high performing 24×7 and, if something does happen, recover to be back in business quickly and without losing any critical data so there is no impact on revenue stream. Of course, there is a gap between this de facto expectation from nontechnical business leaders and what current technology is actually capable of delivering. For mission-critical workloads, which are most often hosted on databases, organizations may choose to implement high availability (HA) technologies within the database to avoid downtime and data loss.
