A hospital replaces aging infrastructure with cloud services but needs to keep control of patient data. Which deployment model is most suitable?

Hybrid cloud is the most suitable model because it allows the hospital to leverage the scalability and cost-effectiveness of public cloud services for non-sensitive operations while maintaining strict control over sensitive patient data within a private cloud or on-premises infrastructure. This addresses the need for modernization (replacing aging infrastructure) while adhering to regulatory requirements and data privacy concerns. Public cloud would not be suitable due to the strict data sovereignty and compliance requirements for patient data, which might not be fully met by public cloud providers. Private cloud would keep all data secure but might not fully address the desire to replace aging infrastructure with cloud services and benefit from cloud elasticity. Community cloud is designed for specific communities with shared concerns, but it doesn't inherently solve the hybrid need for both control and cloud service adoption for varying data sensitivities.
