Topic 2.1 Computer Networking and Cloud computing

[Saranath]

You would like to develop a web-based application for patient appointments. The application will allow a patient to make doctor appointments online. For making an appointment, a patient must provide information, such as name, citizen ID, Hospital number (if available), clinical signs and symptoms (to send the patient to the appropriate clinic).
This web-based application requires a computer network and server to operate. However, there is only one IT officer in your hospital, mostly working on fixing computers. Your hospital does not have its own server yet. You propose to the executive board that a cloud server should be used for this project. So, you must provide information to the executive board.

– Why would you choose cloud server, rather than physical server?
– What kind of cloud computing service model would be most appropriate (SaaS, PaaS, IaaS)? Why?
