A cloud computing based framework of group-enterprise service integration and sharing

The emerging cloud computing technology provides high reliable, low cost, diverse public cloud services to enterprises. When the group-enterprise carries out the private cloud computing framework in their intra information system, a large number of redundant IT resources which are used to ensure information system reliability in tradition system architecture are released. In order to help group-enterprise use public cloud service tentatively and safely, and efficiently utilize the released redundant IT resources, this paper proposes the cloud computing based service integration and sharing (SIS) framework for group-enterprise. This framework aims at realizing services integration and sharing for subsidiaries inside the sub-domain, services sharing among different subdomains, utilization of public cloud service by subsidiaries.
