Destroy/Create is an option for newer applications or services however my concern was more for legacy based services which is more a case of saving the machine moving it or in the better case, live migrating it.
Thanks for the input Pieter On Aug 18, 2014, at 02:25 PM, "Scott C.

Much the same way folks embracing devops would move from dev to test, or from staging to production. That way your app becomes truly portable and much more 'cloudy'... the more you can abstract how you manage your app from the underlying infrastructure, the happier you'll be long term in a cloud environment. Hope that helps! -Scott http://metacloud.com On Mon, Aug 18, 2014 at 7:54 AM, Jyoti Ranjan <jran...@gmail.com> wrote: It depends upon which hypervisor you do use. For e.g. if you are ESX then they have concrete solution to migrate VMs (you can configure your data center like that). But, it we are using KVM hypervisor then something is cooking in direction and migration is not fully automated.

I understand that OpenStack can be split into availability zones and then regions so for example sake a zone is different data-hall's or racks within the same data centre and a region is another country or data centre. Is it possible to live migrate a virtual machine from one zone to another? Same question I suppose could apply to a region but I understand networking could be an issue if the region is a different network?
