A hybrid is a mixture of two different things, resulting in something that has a little bit of both. Like the rare zeedonk, a hybrid of a donkey and a zebra. Hybrid refers to many areas of life biology, electrical power generation, electronics, film, games and sport, music, literature, vehicles. Other examples of the use of hybrids

• Hybrid security, a type of economic instrument,
• Hybrid word, a word derived from more than one language,
• Hybrid market, a system allowing stock trades to be completed either electronically or manually,
• Hybrid organization, an organization that mixes elements of various sectors of society

The world around us is a hybrid and it is no longer just a state of transition. This also applies to Cloud Computing. Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Business requires a flexible IT infrastructure that can scale on demand. A hybrid cloud gives organizations the best of both worlds, so company can take advantage of external resources when it makes sense from business perspective. Varied use cases for hybrid cloud composition exist. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service. This example of hybrid cloud extends the capabilities of the enterprise to deliver a specific business service through the addition of externally available public cloud services. Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses. Another example of hybrid cloud is one where IT organizations use public cloud computing resources to meet temporary capacity needs that cannot be met by the private cloud. This capability enables hybrid clouds to employ cloud bursting for scaling across clouds. Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and „bursts” to a public cloud when the demand for computing capacity increases.
