Thanks Alexander for the detail explanation, really very helpful!

What I meant for a windows cluster is actually a windows application, such
as a WebSphere cluster or a hadoop windows cluster.

Seems I can use Cloudbase Init to do the post-deploy actions on windows,
but I cannot do some scale up or scale down for this cluster as currently
there is no cfn-tools for windows, is it correct?

Thanks,

Jay
