Cloud computing in the present scenario is a developing and fast growing technology that is widely being adopted around the world. This is quite flexible, mutual, scalable and lucrative computational approach that has entered in various public domains. Cloud computing utilizes the Internet-based computing power and here the information, data, and other resources are provided to the user via a computer or device on-demand and is being charged on the basis of its consumption. This paper categorizes, presents the refined study of recently published articles on cloud computing, especially in the health care sector. It demonstrates an outline of the prime issues and challenges explores resources and discusses practical techniques and tools practiced in this context. It also provides an insight of various cloud computing applications in several scenarios, current enhancements and describes the possible future directions for a deeper understanding of cloud computing in healthcare. It proposes the recent state of the art used in cloud computing for healthcare.
