An Optimal Web Services Migration Framework in the Cloud Computing

In the traditional SOA architecture, large-scale number of services access and execution may result in the poor performance due to the overload of some nodes, which will seriously affect the quality of services. Therefore, how to establish high quality and reliable Web Services platform has become a research hotspot, especially in the Cloud computing. After analysis of the existing framework in the performance on load balance, the paper proposed an overall optimal framework of Web Services migration for load balance in the Cloud systems. In the proposed framework, two strategies of Web services migration are provided, one is services replication, and the other is services transfer. Under the different situations, the system will dynamically adopt the appropriate services migration strategy based on the nodes´ workload. The experiments results show that the proposed Web Services migration framework and the corresponding strategies can obtain better performance on the load balancing.
