The web-based application for patient appointments on cloud server is more cost-effective than purchasing and maintaining physical server hardware. Since the usage of a healthcare application for patient appointments may fluctuate, cloud servers easily scale up or down based on the application’s demand. Some leading cloud providers offer high levels of reliability and uptime for 24/7 available healthcare services. Their security measures for infrastructure are more likely to be more robust than what a small IT department in a hospital can provide. Also, cloud servers allow the IT officer to focus on application development rather than server management.
PaaS (Platform as a Service) cloud server would be most suitable for the web-based application for patient appointments with the limited IT resources in the hospital and specific requirements of app features. It provides more ease of infrastructure management with more flexible customization than SaaS and IaaS. Thus, the IT officer requires less learning curve for app development training and is able to focus on building the application rather than maintaining the server.
