Reference Architecture and Operation Model for PPP (Public-Private-Partnership) Cloud

Abstract

The cloud has already become the core infrastructure of information systems, and government institutions arerapidly migrating information systems to the cloud. Government institutions in several countries use privateclouds in their closed networks. However, because of the advantages of public clouds over private clouds, thedemand for public clouds is increasing, and government institutions are expected to gradually switch to publicclouds. When all data from government institutions are managed in the public cloud, the biggest concern forgovernment institutions is the leakage of confidential data. The public-private-partnership (PPP) cloud providesa solution to this problem. PPP cloud is a form participation in a public cloud infrastructure and the building ofa closed network data center. The PPP cloud prevents confidential data leakage and leverages the benefits ofthe public cloud to build a cloud quickly and easily maintain the cloud. In this paper, based on the case of thePPP cloud applied to the Korean government, the concept, architecture, operation model, and contract methodof the PPP cloud are presented.
