Abstract
Traditionally healthcare services are deployed on dedicated physical systems and the functionalities are limited to the local network. Mostly, dedicated physical systems are either under-provisioned or over-provisioned. Cloud Computing technology addresses these limitations by dynamically allocating required resources to applications being hosted on such cloud platforms. In this paper, we study the viability of hosting a telemedicine service over Amazon Elastic Compute Cloud (EC2); a public cloud architecture. In particular, we study the performance of our telemedicine service under linearly increasing workloads by using multiple hosting options available in Amazon EC2. The performance analysis of our telemedicine service is based on fulfilling the specific number of requests per seconds under constraint response times. We find that dynamic resource provisioning on the web tier using medium type instances gives better results compared to static allocation using large and xlarge type instances without incurring any bottleneck issues, thereby, making it a feasible solution for telemedicine service providers.
