This paper presents the ideas for modeling groups of interdependent virtual machines in the cloud. The authors call these models virtual environments. This abstraction is built on top of virtual appliances and the services they provide. The authors discuss previous attempts in this domain and present the motivations for working on an uncomplicated model for non-expert users of cloud computing such as Web developers and CS students. Visual and internal representations of the model are presented. Early work on a prototype implementation is described. The authors argue that easier to use models such as theirs are needed for today's and tomorrow's distributed applications.
