Companies are moving more business operations to cloud and hybrid cloud configurations. Others are adding cloud failover instances to their physical server environments for disaster recovery without the cost of building out a disaster recovery site. Yet, misperceptions and concerns about high availability and disaster protection have made decision making difficult for companies moving their mission-critical applications (i.e., SQL Server, Oracle, and SAP) to the cloud, where traditional shared-storage clusters are impractical or impossible. To fully leverage the benefits of cloud and hybrid cloud environments, companies need to separate myths from facts and consider a new approach to HA and DR.
In this slideshow, Jerry Melnick, president and CEO of SIOS Technology, takes a closer look at five common misconceptions surrounding high availability in the cloud and how SANless clusters can help overcome some of the obstacles.
