failover
Application failover must be achieved within 2-4 hours and proceeds several ways depending on the nature of the failure. Here we discuss fail-over only in the context of lost connectivity to the data center with an uncertain time to restore operations at that datacenter. When there is a configuration change, either at the VM level or at the application level, we clone the entire application and store it offsite (at the city?). Should the datacenter fail badly (fire, etc), we provide carinet with the application, and carinet brings up the application at another location.
