Empirical Study of Research Issues and Challenges in Cloud Computing for E-Health Systems-A Review

Cloud Computing could be a hot research area among the researchers in today's world. It is an internet-based pool of heterogeneous resources. Cloud is much more reliable to make availability of resources when required for online users. Resources are provided as a service on demand with pay-on-usage basis. Computing is done on clouds for less cost and maximum utilization of resources. The cloud computing during this paper has been explored the variety of mechanism for providing data security in order that it would be widely accepted by the variety of many users. The aim of the paper is to present cloud computing service models, service providers, deployment models along with research issues and challenges in cloud computing for e-health systems.
