Which cloud model includes two or more private, public, or community clouds, remaining separate while linked by technology?

The hybrid cloud model is characterized by its combination of two or more cloud environments—private, public, or community clouds—that remain distinct yet are interconnected through standardized technologies. This structure allows organizations to leverage the benefits and features of multiple types of clouds. For instance, businesses can utilize a private cloud for sensitive data and critical applications while engaging public cloud resources for less sensitive tasks or to scale resources on-demand.

In a hybrid cloud setup, the separation of environments enables organizations to maintain security and compliance with regulations while also enjoying the cost-effectiveness and scalability that public clouds offer. Interconnectivity facilitates seamless movement of data and applications between the different cloud environments, thereby optimizing operational flexibility and efficiency.

The other options represent distinct cloud models without the specific combination aspect inherent in a hybrid cloud. A private cloud is solely dedicated to a single organization, a community cloud serves a specific community with shared concerns, and a multi-cloud strategy involves the use of multiple cloud services from various providers without necessarily being interconnected as required in a hybrid cloud model.
