Agreed, but you're talking about HA at a different layer - within the applications that will sit on top of the cloud infrastructure. Whilst that's absolutely valid, and a message that needs to be spread more amongst those designing apps for the cloud, it's not addressing the concerns of the OP. We still need to be thinking about HA of the cloud infrastructure components themselves, so that there are less failures for the app designers to have to tolerate in the first place. Darren
