In a hybrid cloud environment, the component clouds are combined with open or proprietary technology, interoperable standards, architectures, protocols, data formats; application programming interfaces (APIs), and so on. **Figure 4** illustrates a hybrid cloud that is composed of an on-premise private cloud deployed by an enterprise and a public cloud serving enterprise and individual consumers.
