There are three common ways an organisation can build a cloud environment: public, private, hybrid (and multicloud, which is the combination of the three).
Vendors often have different views on what hybrid cloud means. Some analysts define hybrid cloud as simply the use of one or more cloud types within the enterprise.
This can be used to extend the in-house cloud infrastructure with offsite resources. It can also be a combination of different cloud solutions, for example, virtual servers from one provider paired with cloud storage from another. Hybrid cloud environments work well for organisations that need to move data quickly.
