Subject RE: DRaaS based on ACS
Date Wed, 10 Sep 2014 14:34:18 GMT
Hi Ilya,

No - I'm referring to DRaaS - nothing to do with DR for ACS itself. The
Double-Take CP&R is software we can install within the Cloudstack
environment to offer DR and replication services to clients that are not
running ACS. Just wondering if anyone else had other options that they've
tried/installed.

Thanks for the reply anyway.

Adrian

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

regards
ilya
