Preface
Cloud computing is the latest computing paradigm which brings entirely new innovations to the Information Technology (IT) industry. Gartner estimated the demand in 2009 for cloud computing at $46 billion, rising to $150 billion by 2013.1 According to Microsoft, cloud computing can help their customers to save up to 80% on the cost of their IT infrastructure.2 Workflow systems have been widely used as software tools to support process automation, and also as middleware services for distributed high performance computing infrastructures such as cluster, peer-to-peer, and grid computing. In the upcoming few years, given the enormous market of cloud computing, there will be a rapid growth of software as a service (SaaS), and we can envisage that cloud workflow system can be one of the competitive software platforms to support the design, development and running of cloud based software applications. Cloud computing has many unique characteristics such
