A Study on Architectures and Problems of Hybrid Cloud in Enterprise Information systems

Abstract

It's become common sense to use a cloud computing for an enterprise information system, but they are still confusing on how to use it.
We think Hybrid Cloud is the answer of this question.
Though Cloud Computing consists of IaaS, PaaS and SaaS, most people seem to discuss without thinking which layer they are talking about.
And so we studied a hybrid architecture of each layer and found problems for implementation and operation.
