A healthcare cloud is used by healthcare service providers for storing, maintaining, and backing up personal health information along with structured management of the health data across multiple healthcare providers. On a daily basis, healthcare services deal with different kinds of digital information ranging from structured to unstructured. The widespread adoption of electronic health records have resulted in an improved patient health and safety as well as significant savings in healthcare costs. Moreover, deploying healthcare records over cloud environment will enable access of critical patient’s information at any time and from anywhere. But many enterprises are facing a major research challenge due to the unavailability of suitable cloud architecture for design, development, and deployment of healthcare services. In this paper, a flexible architecture for SaaS-based healthcare services has been proposed specifically for healthcare applications, which is capable of semi-structured healthcare data management and storing compatible with Health Level Seven (HL7) standard (Hennessy et al. in A framework and ontology for mobile sensor platforms in home health management, 2013; Liu et al. in iSMART: ontology-based semantic query of CDA documents AMIA annual symposium, pp. 375-379, 2009) [6, 7]. HL7 specifies the structure and semantics of “clinical documents” for the purpose of sharing; therefore, data can be easily shared among the applications. © Springer India 2015.
