Which of the following is the composition of two or more clouds that remain as unique entities but are bound together?

The correct choice is based on the definition of a hybrid cloud, which describes a cloud computing environment that combines two or more distinct cloud services while allowing them to remain separate entities. This type of cloud architecture provides organizations with flexibility and greater efficiency, as they can use public, private, or community clouds together while maintaining unique features and security protocols for each type of cloud service.

In a hybrid cloud setup, businesses can leverage the scalability and cost-effectiveness of public clouds for non-sensitive tasks while utilizing private clouds for more sensitive operations, ensuring data security and compliance. This amalgamation allows for seamless integration and communication between the different cloud types.

Other options represent different cloud models with distinct characteristics. A community cloud is a shared infrastructure among several organizations with similar interests and requirements. A public cloud offers services over the internet, accessible to anyone, without a unique setup for individual organizations. A private cloud is dedicated solely to a single organization, providing enhanced security and control, but it does not integrate separately managed clouds. Each of these alternatives lacks the defining feature of maintaining unique entity status while being interconnected, which is the hallmark of a hybrid cloud.
