A hybrid cloud is a cloud computing environment that combines on-premises, private cloud, and public cloud resources. This configuration allows organizations to deploy workloads and data in a way that optimizes performance, security, and cost management.
* Key Characteristics of a Hybrid Cloud:
* Combines private cloud (on-premises or dedicated servers) and public cloud (resources accessed over the internet).
* Allows for the movement of data and applications between private and public clouds.
* Supports scenarios where certain data must remain on-premises for security or compliance reasons, while other workloads utilize the scalability of public cloud resources.
Comparison to Other Options:
* A. Private Cloud: A private cloud is a dedicated environment for a single organization, either on- premises or hosted by a service provider. It does not include any public cloud integration, as seen in a hybrid model.
* C. Community Cloud: This model is shared among several organizations with similar requirements, typically for collaborative projects, and does not blend public and private infrastructure.
* D. Public Cloud: Resources are entirely hosted on a cloud provider's infrastructure and are shared among multiple customers, lacking the private, dedicated resources of a hybrid setup.
