An infrastructure for web services migration in clouds

Considering the features of cloud computing, a new web service migration infrastructure is presented in this paper. The proposed infrastructure takes some essential factors into account, such as server loading, service type, and so on. The work in this paper includes two parts: (1) We introduce an infrastructure for web service migration in cloud. Due to the properties of cloud, we modify and expand the SOA framework. (2) This paper presents an efficient method for establishing a schema of migration decision. The schema is designed to be extensive enough for different providers to determine the tradeoffs on service selection and migration. The application of this infrastructure can minimize the communication cost and improve the service performance when the service providers are widely distributed in clouds.
