Walrus will need a public IP since it needs to be accessible from both the
NC (to gather the images) and from clients (to upload images and use the
buckets in general), so co-locating it with the NC may not be the best
situation for you. I would put all the components but the NC on the
front-end machine, and the NC only on its own.
