As any networking professional knows, downtime costs money. However, few know exactly how much money downtime costs. Estimates, calculations, and incidentals are all open to interpretation. This creates a lot of uncertainty.
Cloud computing is a good tool to use here. Many IT pros are turning to cloud-based technologies to mitigate the cost of downtime. However, is the viability of a cloud migration backed by facts or based on suppositions?
The assumption that cloud services can reduce downtime is founded on the belief that third-party providers deploy all sorts of continuity technology that all but guarantees uptime. That belief, coupled with service-level agreements (SLAs) that make promises about limiting unscheduled interruptions in service, can give you a sense of security. The real question becomes whether that sense of security is false or justified — and, more importantly, whether a value can be assigned to it.
