Enhancing Security of Multi-cloud Architecture using combination of approaches

In Public cloud when it is used for the practical application which is outside the User’s premises, there are several security issues are arising. These can be overcome by the use multi cloud architecture there they are using four kinds of approach like replication of application, partition application system into tiers ,partition of application logic into fragments , partition of data into fragments. In each every approach there are benefits and pitfalls. In the proposed paper we are initiating the idea of combining more than one approach so as to reach security features like integrity, confidentiality, availability, applicability, ease of use and compliance.
