What is a hybrid cloud?

A hybrid cloud is defined as a combination of public and private cloud services, facilitating the sharing of data and applications between the two environments. This setup allows organizations to take advantage of the scalability and cost-effectiveness of public clouds while maintaining sensitive data or critical operations in a private cloud.

By using a hybrid cloud model, businesses can achieve greater flexibility and optimize their infrastructure usage, allowing them to move workloads between private and public clouds as needs change and costs fluctuate. This characteristic of hybrid clouds supports a dynamic approach to cloud computing, enabling organizations to leverage the best of both worlds in a tailored manner that meets their specific requirements.

The other choices do not accurately capture the essence of a hybrid cloud. An environment entirely based on private cloud services refers solely to private clouds, while a cloud setup dedicated exclusively to community sharing describes a community cloud model. Lastly, the notion of a type of cloud requiring isolated infrastructure implies a more rigid structure that does not reflect the integrative and flexible nature of hybrid cloud solutions.
