The next version of Juju should support using the same Juju server
("bootstrap") for many environments. So, on a single Juju server you can
have many environments. So you only need one Juju server, or you might
want one Juju server per customer.

The other thing to consider is high availability. Juju supports HA
today, which means you can tell it to use 3 servers and if one fails
everything keeps running, with a spare just in case.

So, a typical high-end configuration will be 3xHA Juju systems per
customer, which will serve all their environments.

Yes, we do this quite a lot for dense OpenStack deployments. The Juju
server itself is not very busy for a single environment of typical scale.

Yes, but don't walk out the door with it on your laptop :)
