Um. You and I apparently work in different clouds.
In my world, the SLAs I have agreed to state, roughly, that uptime is not
guaranteed, nor is data recoverability. They suggest that that sort of
thing is -my- problem to engineer and architect around.
I don't use Rackspace's cloud solution - but I haven't seen anything to
suggest that they advertise their service any differently.
The "cloud" provides flexibility and rapid deployment at the expense of
hands-on control and reliability (and SLAs).
Perhaps you forgot to read the SLA? Or you can show us where someone
defines "Cloud" as "highly available" and "without indefinite downtime" ?
