Cloud computing is an emerging computing paradigm.
It aims to share data, calculations, and services transparently among
users of a massive grid.
Although the industry has started selling cloud-computing products,
research challenges in various areas, such as UI design, task
decomposition, task distribution, and task coordination, are still unclear.
Therefore, we study the methods to reason and model cloud computing
as a step toward identifying fundamental research questions in this paradigm.
In this paper, we compare cloud computing with service computing and
Both the industry and research community have actively examined these
three computing paradigms.
We draw a qualitative comparison among them based on the classic model
of computer architecture.
We finally evaluate the comparison results and draw up a series of
research questions in cloud computing for future exploration.
