Continuous Availability

In the ideal world you would never have to think about email, data base, BES, name the application ceasing to function.  Equipment would always work, applications would always be seamless and human error would not exist.  CAPEX would have a longer cycle and OPEX would be practically non-existent.  A pleasant fiction.  Where you live, a transparent failover of production applications, data, OS, network and hardware is required.
