Yes.

The cloud-node image is useful to allow you to set up a new cloud node 
in short order, 5 minutes or less. If you just run your own small cloud 
and you do not plan on adding another cloud node then building an image 
is overkill.

Having the images also has the advantage that they encapsulate the 
knowledge of how to set up and configure a node (head or cloud). Once 
you have an image and the need for a new node arises you can just 
install the image and do not have to go through the whole configuration 
process again.

KIWI does not need to be installed on the cloud machines at all. KIWI 
just needs to be installed on some machine that can function as your 
image build machine.

HTH,
Robert
