On-demand self-service, broad network access, resource pooling, rapid elasticity, and measured services describe what according to NIST?

The correct answer is identified as the essential cloud characteristics defined by the National Institute of Standards and Technology (NIST). These characteristics represent fundamental aspects that define cloud computing and differentiate it from traditional IT solutions.

On-demand self-service allows users to provision computing resources as needed without requiring human interaction with the service provider. Broad network access signifies that services can be accessed through various networked devices. Resource pooling refers to the provider's ability to serve multiple consumers using a multi-tenant model, where resources are dynamically assigned and reassigned. Rapid elasticity indicates that resources can be scaled up or down quickly to match demand, and measured services allow for monitoring, control, and reporting of cloud usage, ensuring transparency and billing accuracy.

These characteristics are integral to understanding what constitutes a cloud computing environment and help define the services and processes that cloud providers offer. They work together to create an efficient, scalable, and user-friendly computing model, which is at the heart of modern cloud solutions.

In contrast, core cloud services refer to the specific functionalities, such as computing, storage, and networking capabilities, provided by cloud solutions. Deployment models classify the way cloud services are delivered to users but do not focus on the inherent characteristics of those services. Security measures pertain to safeguards put
