Architecture for Inter-cloud Services Using IPsec VPN

Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Cloud platform services, delivers a computing platform and/or solution stack as service, often consuming cloud infrastructure and sustaining cloud applications. In future cloud computing architecture enables many cloud services to connect to each other freely. Using IPsec VPN it will increase the complexity in terms of security policies along with the evolving cloud architecture. In this paper, we discuss how we can introduce IPsec VPN in inter-cloud computing architecture.
