Abstract
In this chapter, we will present an overview about the background of cloud computing and workflow systems. Specifically, Sect. 1.1 introduces the novel cloud computing paradigm. Section 1.2 reviews the workflow systems, especially in the distributed computing environments. Section 1.3 introduces the cloud workflow systems. In Sect. 1.4, we demonstrate two motivating examples, one for large-scale data and computation intensive e-science application in Astrophysics and one for instance intensive e-business application in the stock market. Finally, Sect. 1.5 points out the key issue in the design of cloud workflow systems.
