Open Stack

I believe you just described Murano.

Rather then make each OS user have to be a developer and custom deploy every app they want to run, they split the effort in such a way that Developers can provide software through channels that Users that are not skilled Developers can consume and deploy. The "App" culture in the mobile space it the epitome of that at the moment. My grandmother fires up the app store on her phone, clicks install on something interesting, and starts using it.

You have to find the software your interested in, figure out which components your going to consume (nova, magnum, which COE, etc) then use those api's to launch some resource. Then after that resource is up, then you have to switch tools and then use those tools to further launch things, ansible or kubectl or whatever, then further deploy things.

The number of users that could use such an interface, and consume OpenStack resources are several orders of magnitude greater then the numbers that can manually deploy something ala the procedure in the previous paragraph. More of that is good for Users, Developers, and Operators.
