Cloud computing is a broadly used technology which serves users with resources on specific demand enhancing manageability, minimizing the data management and operational cost. Basically, cloud allows users to store their valuable data on the cloud storage so the security of the data center and easy access are considered as focusable parts in cloud computing. In the study we spot light to a new approach of cloud computing where mobile storage is used to build the data center of cloud and easy access having a preferable security. We deliberate that it is possible to lower the cost if the data center is built using user's mobile storage so a 3-tier technology is proposed. Firstly, a layer is user's mobile devices, second layer is server with different virtual machines and last layer is again the user's mobile device which is used to build the data center of cloud (mobile-server-mobile). A mobile app implements the initial security and management issues. Users can oscillate data between first layer and third layer with the help of virtual machines that ensure secure transaction of data, reduction of power consumption, maintenance cost, bandwidth consumption and fast data sharing.
