Cloud based healthcare : Requirements and Challenges Sudarshan Sargur Graduate Student Dept. of ECE University of Arizona, Tucson, AZ Abstract—Cloud computing is a computing paradigm which is gaining popularity and emerging as a cost effective, services rich alternative in a multitude of domains. Adoption of cloud based systems in health care offers an opportunity to make the idea of ubiquitous and timely health care a reality. Health care IT involves handling large amounts of data and sharing them between different health care providers. This involves dealing with large data files such as various medical images, patient records, etc. The cost of sharing these among different health care providers is a time consuming and costly…show more content…
It is therefore a very exciting new paradigm which promises to offer many solutions to businesses which are willing to adopt it, at a very low cost. In the field of healthcare IT, the emergence of cloud based computation plays a major role in new opportunities and applications. There are many advantages of cloud such as the fact that the services are provided and managed by the cloud service provider. Therefore, the IT setup, maintenance and upgrade costs spiral down significantly for all the healthcare providers willing to adopt cloud based systems. Further, having a multi-tenant cloud based system instead of setting up IT infrastructure at every healthcare provider’s premises proves can be an energy conservation method which also drives down the operational costs significantly for healthcare providers. Further, most importantly, cloud works as a pay-as-you-use service wherein the cloud provider offers a vast array of services to his/her customer but the customer has the option to choose which services are needed and pay only for those. Therefore the customer can choose at any time to opt out of a service and pay only for the usage. Such a model is helpful because it helps share infrastructure and service. There are various other healthcare opportunities such as providing a platform for ubiquitous healthcare and patient diagnoses. Therefore with a unified computational
