A public cloud is defined by its accessibility to anyone who wants to use it, making it available for use by the general public. This characteristic distinguishes public clouds from private clouds, which are restricted to a specific organization. In a public cloud, resources such as servers and storage are owned and managed by third-party providers, and multiple users can share these resources, leading to increased scalability and reduced costs for end-users.

The concept of a public cloud inherently involves a model where the infrastructure is not limited to a single organization, allowing a broader group of users to access various services without the need for significant investment in physical hardware or maintenance. This open model emphasizes the principle of shared services, benefiting from economies of scale and flexibility, as users can adjust their resource consumption based on demand.

While other options focus on attributes like limitation to a single organization or requiring physical infrastructure, they do not align with the fundamental nature of a public cloud, which thrives on openness and shared resources.
