Cloud Deployment Models - XML

Cloud deployment models are classifications defined in NIST SP 800-145 that indicate how cloud computing infrastructure is operated. There are four basic models - Public Cloud, Private Cloud, Community Cloud, and Hybrid Cloud - along with a derivative model called Multi-Cloud. Each model is classified based on differences in infrastructure ownership, users, and operational methods, and is selected according to an organization's security requirements, cost structure, and compliance needs. These models serve as an important foundation for standardizing cloud computing and formulating organizational cloud strategies.
