According to NIST, which cloud computing deployment model supports data and application portability?

The hybrid cloud model is recognized for allowing data and application portability between different environments, which is a critical aspect of modern cloud computing strategies. This model combines elements of both private and public clouds, providing the flexibility to move workloads and data between on-premises resources and public cloud services.

By enabling this kind of interoperability, hybrid clouds facilitate a more adaptable infrastructure where organizations can manage their workloads based on varying requirements, such as security needs, traffic spikes, or cost considerations. This model supports seamless integration and movement of applications and data, making it easier for businesses to optimize their operations and respond to changing demands.

In contrast, private and public clouds typically do not offer the same level of portability because they are bound to their own environments. Community clouds also have specific restrictions as they are designed for shared infrastructures among particular communities that may limit mobility across other cloud models. Thus, the hybrid cloud deployment model stands out for its strong emphasis on portability, matching NIST's guidelines for cloud computing.
