[Pacemaker] Article on HA in the IBM cloud using Pacemaker and Heartbeat

[Alan Robertson]

Hi,

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

http://www.ibm.com/developerworks/cloud/library/cl-highavailabilitycloud/

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.

There will be a follow-up article on setting up DRBD in the cloud as 
well...  Probably a month away or so...
