Which of the following best describes a computing environment that connects an organization's on-premises private cloud and a third-party public cloud?

A hybrid computing environment is characterized by the integration of both on-premises private clouds and third-party public clouds. This setup allows organizations to benefit from the unique advantages of each type of cloud. By utilizing a hybrid model, companies can maintain sensitive data in their private cloud while leveraging the scalability and additional resources of a public cloud for fluctuating workloads and less sensitive operations.

This flexibility ensures that organizations can optimize their cloud usage, making it easier to move workloads and applications between the private and public environments as needed. This adaptability not only enhances efficiency but also provides a path for organizations to innovate and respond quickly to changing business demands.

In contrast, a public cloud solely refers to services offered over the internet to multiple customers, while a private cloud is dedicated to a single organization, often requiring significant control over security and compliance. A community cloud serves a specific community with shared concerns, but it does not encompass the broader utilization of both public and private environments that defines a hybrid cloud model. Therefore, the hybrid cloud is the most accurate description for a combined on-premises and public cloud setup.
