Cloud computing supports an online infrastructure where computing resources are provided as a service over the Internet. This paper proposes a new model exploring the concept of sharing a common infrastructure and service by top to bottom level business organizations to increase business opportunity while providing isolation and security to end-users. User identification IP based security and elasticity, i.e., enabling of variable amount of services to be drawn from the cloud are also provided. The proposed model incorporates Software as a Service (SaaS) which is a rapidly growing model for software licensing.
