Short-term need informing long-term design: Landscape integration

[Gary Poster]

Hi Alejandra, Nick and everyone.

The GUI devs should be starting work on Landscape integration very soon.
 I currently suspect it will be the week after next.

Short-term, that will involve adding some links and visual indicators to
the current interface, and we'd like your advice and guidance with that.
 Longer term, you'll want to incorporate these stories into the revised
UX that you are working on now.

I currently have a list of the technical changes we've been requested to
make.  I'd like to reverse engineer those into user stories we want to
tell, and then plan the GUI changes from those stories.

So, to put the cart before the horse, here are the technical changes we
have.  To be clear, a "Landscape link" means a link to the Landscape
application.

* We have a Landscape link to view/manage the machines that represent
the current environment.

* We have a Landscape link to view/manage the set of machines that
represent a given service.

* We have a Landscape link to view/manage a single machine that is
running a given service unit.

* We have information about whether a unit is on a machine that needs
security updates from Landscape.

* We have information about whether a unit is on a machine that needs a
reboot from Landscape.

Example user stories (Emmanuel is our SA persona):

Emmanuel wants to use the GUI to monitor the health of his juju
environment.  He goes to the GUI environment and looks at his services.
 He sees that there are no markers indicating a problem, and so he goes
off and does something else.  He comes back later and sees an indication
that the mediawiki service has some machines that need a security
update. He gets an option to go to Landscape and resolve the problem,
which he takes.  The browser opens Landscape, replacing the GUI.  He
does not need to login, because he was using it recently.  He sees a
list of all the machines that need a security update in the environment,
and confirms that he wants the update to happen.  He then sees an option
to return to the GUI, which he takes.  He does not need to log in (devs:
Kapil wants to use http://code.google.com/p/sessionstorage/), and
returns to approximately the same view he was on before.

Emmanuel is looking at the GUI, and wants to check the more detailed
status of the environment's machines in Landscape.  He takes an option
to go to Landscape.  This moves the browser from the GUI to Landscape.
He logs in.  He investigates a bit, makes some changes, and then is
finished.  He then decides to return to the GUI.  He does not need to
log in again to the GUI.

Emmanuel is looking at the GUI and sees there is a Juju error in the
mediawiki service.  Investigating, he sees that only one of the units
has a problem.  He decides to look at the unit's machine in Landscape to
see if he can get more information to diagnose or fix the problem.  He
takes an option to go to Landscape.  This moves the browser from the GUI
to Landscape to look at that machine.  Emmanuel investigates and
resolves the issue.  He returns to the GUI from Landscape and marks the
unit as resolved.

Thanks
