Public cloud, as it offers the highest level of scalability and cost-effectiveness, with built-in security features that can be customized to meet regulatory requirements. However, it may not provide the same level of data control as other models.

Private cloud, as it provides the highest level of security and control over data, making it ideal for sensitive data and compliance with regulatory requirements. However, it may involve higher costs and limited scalability compared to public cloud options.

Hybrid cloud, as it combines the scalability and cost-effectiveness of the public cloud with the security and control of the private cloud, offering the flexibility to place sensitive data in the private cloud while utilizing the public cloud for scalable resources during peak times.

Multi-cloud, as it allows the institution to use multiple cloud services from different providers, offering the best features of each. However, it may complicate compliance and data security due to the varied environments.
