Adrian,
If i understand the task correctly, you are trying to have replica sets
across datacenters with ACS functional.
I can think of a solution that does not require heavy investment.
1) you replicate the VM disk content across to datacenter X
2) you replicate db content from cloudstack, you can just fetch the
content from ACS via APIs and re-load the content into secondary ACS.
Alena from Citrix explained how she did it @ CCNA14 in Denver.
3) needless to say, you IP between datacenters will change, so VMs
should know how to handle that change

Hi All,
We’re currently looking into the possibility of creating a DR as a service
offering for our customers based on ACS. I’m assuming that trying to create
a fully open source solution is not feasible and am looking to evaluate
Vision Solutions’ Double-Take Cloud Protection and Recovery product. I’m
wondering if anyone knows of any other solutions that would work nicely
with ACS (i.e. client self-service, handling the import of a VM into ACS,
WAN ‘optimised’ communications etc).
From what I can tell, the main problem with most commercial solutions is
that they assume that they have direct control of the hypervisors,
bypassing ACS completely, and as such would result in creating a VM that
ACS would then not be able to see or therefore manage. They also seem to
assume that there’s a private network between the source and target systems
which can be an issue with multi-tenancy and overlapping IPs between
tenants. I’m initially looking for Xenserver support as well which seems to
be the ugly duckling when it comes to backup and replication – most of the
commercial solutions concentrate on VMware and then Hyper-V.
Does anyone have any experience with either the Double-Take or any other
solutions that they’d care to share? Anyone know of any yet-to-be-released
solutions that might fit the bill?
Many thanks,
Adrian
