As far as I’m concerned, people cannot agree on what a framework really is, much less what cloud is. I believe the Wikipedia “Category:Cloud platforms” [1] conforms most closely to Infrastructure-as-a-Service (IaaS) and/or Platform-as-a-Service (PaaS) . Myself I am most Interested in cloud middleware, but have only found a few visual IDEs; see my recent survey of “Artificial Intelligence Middleware” [2]. You may also be interested in my survey of “Application Programming Interfaces” [3].
