The correct way to think about this problem, is how to architect your software such that an instance failing becomes "not important", causes no data loss or service interruption Regards </div> -- Ubuntu-cloud mailing list <a href="mailto:Ubuntu-cloud@lists.ubuntu.com">Ubuntu-cloud@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-cloud" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-cloud</a> </blockquote></div> Ahmed, Thanks for your reply. It's my first attempt with private cloud. I've worked with virtualization (ESXi & Oracle VM) and the disaster recover in case of node failure is what I am trying to know in case of private cloud. I would be grateful if you can brief about how to define disaster recovers practices in a private cloud. I don't architect all the applications I do use so I am looking for he disaster recovery practices in the cloud architecture. thanks -- Mustafa Qasim <img src="http://www.google.com/sync/images/gmail.png" alt="" height="16" width="18"> <a href="mailto:mustu@linux.com" target="_blank">mustu@linux.com</a> <img style="vertical-align: baseline;" src="http://www.copywriting.com/pix/icon-blog.gif" alt="" height="18" width="18"> <a href="http://blog.mustu.info/" target="_blank">http://blog.mustu.info</a> <a href="https://www.linuxfoundation.org/about/join/individual?lftrkr=MEMWIDGETb300x100_2010" target="_blank"><img src="https://widgets.linuxfoundation.org/badge.php?size=300x100&lfu=NWU0ZmQ0ZjZjZWM4ZmFkZWFkMWZlNTMyZmQ2MmFkZTg6bXVzdHU="></a>
