Cloud computing is an "emerging paradigm" in the field of Information Technology for scalable, internet based, real time applications and resources to satisfy end users' needs. This state-of-the-art technology is utilized in vital healthcare services to incorporate emerging applications such as remote patient monitoring, electronic health record and collaborative consultation. In this paper we plan to propose the architecture of a cloud-based healthcare application intending to serve patients in emergency conditions. A centralized cloud database would hold individual's medical history in a single summarized document. In case of any accident or emergency situation, the patient's previous medical history can be retrieved from the cloud database before starting any crucial operation. This system can also be integrated with state owned unique identification number systems. © Research India Publications.
