I've written a couple of blog entries on my personal blog which are related and which people may find interesting. The first is on some work I was doing over Christmas with CapeDwarf running on Raspberry Pis, with the aim to turn them into a private cloud. The second is about the adoption of hybrid cloud, but also repeats what I've been saying for several years that devices such as the Pi (or smaller) need to become part of the cloud. I'm hoping to say more about this at Summit later this year and maybe we'll have some demos to illustrate.
