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.
