Simon, Agree completely, that's why we are working on bringing Zone HA to CloudStack, for both Enterprise Nd Public Cloud use cases - watch this space

Most of our customers are traditional enterprises who who have invested vast sums of money on SAN/NAS environments, and they typically run large VMware farms. Today they are able to implement a DR Solution by using SAN/Hypervisor replication and automation tools such as VMWare SRM. This typically works very well (at a cost), considering some of our customers have over 800 applications in their portfolio. Most, if not all of our customers run very traditional, vertically scaling applications that are central to their business. Assuming they are going to re-write their very complex and expensive application stack so that they can leverage cloud technologies is a flawed argument. The cost of such an exercise may run into the 10^1s of millions for some organisations. In any case, I really hope this feature is developed. Without it, Cloudstack (and other cloud platforms) will make limited headway into risk adverse enterprise accounts who have had this capability for many years. Although I fundamentally agree that to really harness the power of cloud, your applications should be OEcloud native^1, I also think that cloud platforms should be flexible enough to cater for traditional workloads and not doing so it a major inhibitor to cloud adoption for enterprises.

This feature can be on their list all they want, it's _extremely_ unlikely it will happen any time soon. Imagine the amount of efort required to replicate tons of storage and the omnipresent danger of split-brains... this has DISASTER written all over it, not RECOVERY. :-) The application needs to be cloud-aware as you say, in most cases this is actually doable; though of course, some people are stuck with old technology - they can just live with the risk or adapt to a cloud environment.
