What type of cloud allows users to access resources across public networks?

The correct choice is a Public Cloud. This type of cloud computing is characterized by its accessibility over public networks, allowing users to access and utilize a variety of resources—such as servers, storage, and applications—through the internet. Public clouds are operated by third-party service providers, which manage and maintain the infrastructure, enabling organizations to scale their resources based on demand without needing to invest in physical hardware or dedicate in-house IT resources.

Public clouds typically offer a variety of services on a pay-as-you-go basis, making them a cost-effective solution for individuals and businesses that need to access scalable computing power. They are widely used for a range of applications, such as web hosting, data storage, and software as a service (SaaS).

In contrast, private clouds are designed for a single organization and are not shared with others, typically providing better security and control. Hybrid clouds combine elements of both public and private clouds, allowing data and applications to be shared between them, while community clouds are shared among several organizations with common concerns.
