Message from the WMSC2012 Workshop Chairs

The 4th International Workshop on Workflow Management in Service and Cloud Computing (WMSC2012) was co-located with the International Conference on Cloud and Green Computing (CGC2012) held on November 1-3, 2012, Xiangtan, Hunan, China. As emerging paradigms, service and cloud computing enable resources 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 WMSC2011 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. WMSC2012 contains 3 papers. Each of them was peer reviewed by at least three program committee members. The workshop covers a broad range of topics in the field of Workflow Management in Service and Cloud Computing such as Service Delivery and Composition, Service Level Agreements (SLAs) Negotiation, Automation and Orchestration, Quality of Services for Workflow Execution, Workflow Verification and Validation, Services Repository and Registry, Service Security, Privacy and Trust for Workflow Modelling and Execution, Novel architectural models for cloud computing in support of workflow execution, Cloud Workflow Architecture, Cloud Resource Management, Scientific computing in the cloud, Programming models for cloud computing, Access control and authorisation for workflow execution, Workflow scheduling in cloud computing, Utility models and service pricing, Service enabled workflow applications and Cloud workflow applications.
