Which cloud model involves using both private and public cloud resources in combination?

• A. Community Cloud
• B. Public Cloud
• C. Private Cloud
• D. Hybrid Cloud

Answer: (D)

The ability to use both private and public cloud resources together is what defines a hybrid cloud. It lets an organization keep sensitive data and critical applications in a private cloud while drawing on the scalability and breadth of services available from a public cloud when needed. This flexible mix allows for scaling workloads up or down, optimizing costs, and applying governance and security controls across environments. A private cloud is dedicated to a single organization with tighter control over security and compliance, a public cloud provides widely available, on-demand resources shared among many users, and a community cloud is shared among a group with common concerns. The combination of these two types of resources in one strategy is the hallmark of a hybrid cloud.
