A hybrid cloud is considered as the integration of multiple clouds that are aligned to the unique characteristics of different system types. IBM® defines a hybrid cloud as a secure
cloud computing environment that uses services from two or more sources, such as a private cloud, public cloud, or traditional IT sources.
A hybrid cloud transforms roles throughout the organization and allows business leaders and developers to innovate efficiently and faster. Applications that are built around a hybrid cloud infrastructure typically revolve around at least one of the following pillars of hybrid integration:
API-centric applications
Data-centric applications
Event-centric applications
