The correct answer is 'Hybrid cloud'. This model is designed to allow organizations to combine the benefits of both private and public clouds. It provides the flexibility to use the public cloud for scalable, less sensitive workloads while keeping more sensitive workloads secure in a private cloud or on-premises. The hybrid approach allows for data and applications to interoperate across boundaries (public and private environment), which is particularly beneficial for companies with dynamic or changing workload demands, or with legal and regulatory compliance requirements that prevent them from storing data in a public cloud. 'Private cloud' is incorrect because it refers to cloud resources used exclusively by one business or organization, and 'Public cloud' is not suitable for sensitive data due to compliance concerns. 'Community cloud' is a shared infrastructure for a specific community and does not address the need for both private on-premises and scalable public cloud resources.
