Each type of cloud is expected to have a public bucket available into which the
tools are uploaded and are accessible from. In the beginning, there was just EC2
support in Go juju, and at first even Openstack deployments looked into the S3
public bucket. Now, for Openstack, "native" public buckets are supported so if I
deploy to HP Cloud for example, I can specify a HP Cloud URL for a public bucket
which contains the tools. I'm not sure what other providers eg MAAS are doing to
support public buckets but they will need to support them in some fashion.
