DefinitionHybrid cloud (ハイブリッドクラウド) is a model that links environments of different kinds, such as a public cloud and a private cloud (or in-house equipment), and uses each for the purposes it suits.
ExplanationFor example, customer information that must not leave the company is kept in the dedicated environment, while a sales site whose traffic swings sharply with the seasons runs in the shared one. The aim is to get both confidentiality and easy scaling. However, the mechanisms and management for moving data between the environments tend to become complicated.
AnalogyChoosing between a meeting room only your staff can enter and a lounge shared by every tenant in the building, depending on the topic. Confidential talks go to the private room; casual catch-ups happen in the lounge.
Memory hookA hybrid car combines two different power sources, an engine and a motor. Mixing things of different kinds is the clue behind "hybrid."
