On the account of instance failure, the App along with its floating IP should failover to another running instance. Any best-practices or suggestions will helpful to proceed further.

You want to be running two instances in parallel on separate Compute Nodes. One with the App and floating ip and another running in a passive/inactive mode. If the first instance fails, the floating ip would move over the the already running second instance which is on a separate compute node? If that's the case... maybe there are some things via Heat that could do this? Adding zbitter to comment. If what you're asking is more about failing the whole instance over from one Compute Node to another (if the instance or Compute Node fails), that will also be possible in the near future via our Instance HA feature. Andrew/Fabio can elaborate more on this point. Perry From fdinitto at redhat.com Wed Jun 3 20:04:10 2015 From: fdinitto at redhat.com (Fabio M.

Andrew/Fabio can elaborate more on this point. In case of Instance HA (the whole instance is rebuilt and failover) then the floating IP will also move. Fabio
