This article is based on the excellent and informative presentation that Mark Pollans, HPE Sr. Worldwide Product Manager, gave at the 2017 Connect Technical Boot Camp on how to design and build advanced business continuity (BC) architectures, a rather important topic to Gravic. It is not a question of IF a disaster will occur; it is a matter of WHEN. A thoroughly planned and tested BC strategy helps assure companies that their applications can survive a disaster. BC is about minimizing or completely mitigating the impact of a catastrophe on business applications. A business impact analysis and overall BC strategies should be reviewed at least every two years to confirm that applications meet mission-critical or business-critical requirements. What was not mission-critical yesterday could be mission-critical today. This article also discusses the Critical Application Continuum, recovery time/point objectives (RTO/RPO), costs and durations of outages, and three fundamental data replication architectures: active/passive (classic disaster recovery), active/almost active (sizzling-hot-takeover), and active/active (continuous availability). HPE Shadowbase solutions are instrumental in assisting customers in deploying and leveraging these advanced BC architectures.
