Thanks!  Sonny, Pranav and Brian Federle did the UI screenshots for me. So credits to them.

I'll say this.. I wish the CloudStack UI looked like the marketplace proposal. Very slick!

Thanks Joe for the inputs! My comments inline. Chiradeep, thanks for the names!  You are sure
more creative than I am :)

Probably just as well, some of us aren't using gui mail clients. ;-)

The feature itself - having a way to list a "marketplace" of templates/images for CloudStack
users - sounds great. 

Companies like Citrix that ship a CloudStack can distribution like CloudPlatform populate
a marketplace with templates, etc. from their partners. Providers like Contegix could populate
the marketplace with their own offerings, etc. 

I'm not so sure about turning this feature on by default in ACS, though.
[Jie] I am thinking to turning this on by default in ACS so that it is visible immediately
to CloudStack admins after installation. This is really a way to make sure admins actually
know about the new feature. There will be a global configuration that admin can turn this
feature off entirely.

Separate governance body? I'm guessing what you mean here is a subset of volunteers from the
committers/PPMC, etc.? 
[Jie] Yes.

I think we have our hands full testing Apache CloudStack. Trying to test third party templates
that would run on CloudStack seems like a *lot* of work. 
[Jie] I think we only need to test the listing, but not the actual templates. Otherwise, I
agree it will be too much work. How do we test vendor plugins today?

I'm not sure about whether vendors would need to sign the CLA, but I'm not entirely clear
on *what* it is that we'd be providing, exactly.
[Jie] Can you clarify more for the CLA?  I thought that anyone contributing anything to CloudStack
source code tree needs to sign CLA?  Is that true?
If we package the listing repository in the source code tree and ship with CloudStack distribution,
I assume vendors who puts the listings there needs to sign the CLA.

If I understand correctly, we'd be providing a pointer of some kind to images, etc. hosted
elsewhere? Obviously, we would not be able to host the images themselves given licensing/space
issues. 
[Jie] Yes, for templates/ISOs, vendor will provide a pointer to image hosted elsewhere. We
will not host it in Apache.

Hosted where? How? What format is the listing going to be in? What kind of technical requirements
are we talking about? 
[Jie] That's my question also. Where can we host it if not in the source code tree? Apache
CloudStack website? See wiki for format:

This would also be true of Option 1, yes? 
[Jie] For option 1, we will test the listing itself as part of the Apache CloudStack governance
process we use for the source code, so that we don't need to create a separate governance
process. We can only go as far as testing the listing does not include virus. We cannot test
the templates/ISOs (too time consuming). Should this be similar to vendor plugins?  In the
case of vendor plugins, we can only test the plugins.
Vendors' products can evolve outside of CloudStack and if they put some virus in, there is
no way we can govern that.

>  *         No Apache listing repository

This has my vote so far. 

If I understand the feature correctly, I would say the marketplace should be an optional feature
that can be turned on at compile time
- perhaps with a configuration that lets you point to one (or more) managed marketplaces provided
by third parties. That way if a company or group wants to manage a marketplace, they can publish
the URL it can be found at and users can flip the switch to get that. 
[Jie] You are correct that there is configuration item that lets you point to one (or more)
marketplace repositories. My proposal is to turn the feature on by default as explained above.

> What should be the name of this new component?

Marketplace seems fine to me, seems descriptive enough and doesn't overlap with other names
currently.
