Load balance between datacenters

[Jesus arteche <chechu.linux@gmail.com>]

Hey guys,

I am trying to create a ha infrastructure. I would like to have my infrastructure in a cloud/vps provider in europe and a replica in USA. I will create load balancers in a HA mode. My problem comes up when I think how to share the floating ip. I mean in a datacenter with the same range of IP is not a problem...but when the datacenters are in different ranges of ip's ...it shouldn't work...

Any ideas about how to do it?

I'm using HAproxy and keepalive...

Thanks in advance
