What is the minimum number of nodes for an Ubuntu Cloud?

Question

What is the minimum number of nodes required to setup a functioning cloud as described in this tutorial:

I just want to run some tests and I don't have 10 computers lying around to do so. Is it possible to use 2-3 nodes(+1 for the MAAS server)?

Each time juju deploy is called it starts a new machine. Also, juju bootstrap reserves a machine to start up zookeeper.

So it looks like that example needs about 9 nodes.

Since you don't have 10 machines, you could do the simple example here.

That link to the simple example is ... well not quite dead but not exactly leading to any example :-) – guntbert Jan 17 at 19:42

You can use juju-jitsu to set the same in 6 machines.

In this case, glance and dashboard goes on same machine as keystone and rabbitmq-server goes along with mysql server. Thus you save 3 machines.
