A hospital is planning how to deploy its digital services and must balance scalability, cost, and protection of sensitive patient data. They are considering three options: Option A: Keep all patient records, billing systems, and internal medical applications on infrastructure owned and managed by the hospital in its own secure data center. Option B: Move all applications, including patient records, appointment booking, and the hospital website, to a large cloud provider’s infrastructure that is shared with other customers. Option C: Keep patient records and billing systems on hospital-owned infrastructure, but host the public website and appointment-booking application on a large cloud provider. The two environments are securely connected. a) For each option (A, B, C), identify whether it corresponds to a private cloud, public cloud, or hybrid cloud deployment model, and justify your choice in one or two sentences. b) Which option offers the best trade-off between data security, scalability, cost, and administrative complexity? Mention one possible drawback of your chosen option.
