A hybrid cloud is a computing platform built from both private and public cloud components. A public cloud is what usually comes to mind when we talk about cloud computing: storage and compute resources offered by a vendor to customers who pay on a metered basis and don’t have to worry about provisioning and managing the underlying infrastructure.
One drawback to using public cloud resources is that they often run in virtualized environments, and customers share hardware and other resources. As an alternative, a customer could set up a private cloud themselves on their own infrastructure, offering the same sort of flexible access to compute resources to internal users.
