IaaS layer is used for providing the primary services to the customers. This is also called providing the primary infrastructure which is the provision of hardware components as well as related software i.e.., network, services, Os etc.The customers who uses this delivery model has a small control over the infrastructure of the cloud as payment depends on the usage of services.

Private cloud provides improved security constraints for the cloud users to provide protection for the data during the times of natural diaster.Because of this reason many users whose interest in adoption of private cloud mechanisms. It enhances the separation levels between the services and infra of the cloud. Although it is beneficiary there is several issues like unbalanced resource utilization which needs to be taken into the consideration. For isolating the private cloud there is a solution of using the OS over a VPN. One of the examples of the private cloud is eucalyptus systems. The organisation adapted this type of cloud type usually controls the unauthorized users for accessing the data (B, Vangie, n.d.)(Data Security Issues and Challenges in Cloud Computing, Nov
