[one-users] Load balancing in hybrid cloud

[Ruben S. Montero]

Hi Tom,

OpenNebula's placement algorithm (match-making by default) only works
at allocation time. You can specify if a VM can be placed in a local
(private) or remote (public) cloud, you can even specify a rank to
different clouds or hosts [1], but OpenNebula does not balance the
VMs. A load balancer could be easily implemented with the OCA API, you
can check our JAVA[2] and Ruby[3] bindings...

Cheers and good luck

Ruben
