Akshat,
Just to chip in some of my thoughts on this since we (disclosure, I'm a
researcher at Lenovo) have had extensive discussions on a similar use
case and consequently come down to the same challenge as you are
currently looking at.
1. Juju CLI allows user to select controller, which essentially leads to
a particular cloud/provider (these two are 1-1 mapping). Therefore, in
practice it already supports multi-cloud scenario (last time I counted
12 clouds out of box including local LXD and manual). The catch is, of
course, the manual step of selecting the proper controller.
2. There are two schools of thought -- whether to have Juju being more
intelligent so to handle multiple clouds `automatically` (for example,
in bundle YAML specify which cloud a charm should be deployed to, which
is one step further than OS series), or using Juju as-is and utilize
something else as a wrapper to facilitate such mixed-cloud automation.
The former option minimize tech stack so there is one set of technology
to learn and manage; the latter gives flexibility, mitigate vendor lock
in... I think the theme is not new, so it's really a matter of design
preference
Juju team has done 90% of the heavy liftings. The former will require
more in-depth of Juju knowledge, the latter requires less. I think the
requirements, however, is clear, that there is a higher level of
abstraction required above the current Juju existence so to drive this.

Thank you Feng,
As I understand for now there is no way to use multiple providers with
juju either with a GUI or command line.
My goal is to be able to allow users to deploy charms (mostly
wordpress/drupal/ghost) on a cloud of their choice. Anything that
allows me to do this is acceptable. The only requirement is maximum
cloud coverage. So for a multi cloud setup what options do I have?
- Should I go for one controller per cloud setup?
- Can juju api <https://godoc.org/github.com/juju/juju/api> help me
write some custom code that'll allow me to do what I want? If so what
should I be looking for in the documentation?
- Since juju runs in an lxc would it be a good idea to create clone
containers that can switch the cloud environment on demand? Or would
this cause more problems that it'll solve?
Thank you once more for being patient with the questions and for all
the answers! Much appreciated
Best,
Akshat

Hi Akshat,
Juju controller does not support multiple cloud/provider. It's
like a switch board, juju can only talk to one controller at a time.
However, I do think there are use case of supporting multiple
clouds with one orchestrator. I'm not sure whether juju team has
sth like that on its roadmap, or maybe using some other tools for
the purpose?

Is there a way I can configure multiple providers using the
Juju-GUI? Also is there a way I can configure cloud providers
based on user access roles? For example a user with access to a
particular model can deploy only to a specific cloud provider.
If one controller can manage multiple clouds and one controller
can have many users then what is the mapping of the relationship
between the users and the clouds?
Thanks,
Akshat
