Which of the following best describes a Public Cloud?

A public cloud is characterized by multi-tenant services that are accessible to all users via the internet. This model allows multiple organizations or individuals to share the same infrastructure and services, which can lead to cost savings and greater scalability. Public cloud offerings are typically provided by third-party providers, enabling users to leverage resources and applications without the need to invest significantly in physical hardware or maintenance.

The essence of a public cloud lies in its open access, where resources can be provisioned on-demand, promoting flexibility and efficiency for businesses of all sizes. This model is particularly beneficial for organizations seeking to avoid the complexities and costs associated with maintaining their own data centers.

In contrast, dedicated services for a single organization point towards a private cloud model, which does not align with the definition of a public cloud. The notion of security for sensitive data predominantly ties into the distinctions between public and private clouds but does not define public clouds themselves. Additionally, requiring a private network connection contrasts with the essence of public clouds, which are accessible via the public internet without the need for dedicated connections. Thus, option B accurately encapsulates the defining traits of a public cloud environment.
