DATA TRANSFER MODEL FOR CLOUD COMPUTING

Abstract

The evolution of cloud computing is one of the major advances in the computing area as well as in economics of computing technology. As an evolving technology it faces challenges like transferring data securely from the data center to the cloud considering the criticality and sensitivity of the data, performance unpredictability, and cost of data transfer. In this paper we provide a cloud computing model with its convergence with 4G technology as a solution for these challenges. This model is primarily for large companies having branches in geographically proximate regions. The model is intermediate between the cloud computing concept and the private datacenter model. Using 4G the data is transferred from the data center to the cloud and back, 4G offers a wide bandwidth of 2-8 GHz and data rate tariffs promise to be cheaper than 3G having data rates of up to 200Mbps for fixed devices. The proposed IP based network of 4G and the design of the model helps to increase the level of data confidentiality in the network. We also prove mathematically that with convergence of Cloud Computing and 4G, the cost of data transfer to and from data center to cloud reduce and also the data criticality and sensitivity issue is ameliorated.
