As emerging paradigms, service and cloud computing enable resource to be employed in utility-based fashion. Workflow automating business and scientific processing in step by step can be executed in service and cloud computing environments in the benefit of deploying resources for execution in that fashion. This workshop following its successful edition of WMSC2012 aims to provide a forum for researchers, practitioners and developers from different background areas such as service computing, cloud computing and workflow area to exchange the latest experience, research ideas and synergic research and development on fundamental issues and applications about workflow management in service and cloud computing environments. The workshop solicits high quality research results in all related areas.
