Hi,
I recently co-authored an article on HA in the IBM cloud using Pacemaker
and Heartbeat.

The cool thing is that the IBM cloud supports virtual IPs. With most of
the other clouds you have to do DNS failover - which is sub-optimal
;-). Of course, they added this after we harangued them ;-) - but still
it's very nice to have.
It uses Heartbeat rather than Corosync because (for good reason) clouds
don't support multicast or broadcast.
Corosync works in non broadcast/multicast modes. (the transport is
called udpu).
Thanks for the correction! It's always better to have ones facts
(unlike how I did here).
