Which of the following describes a public cloud?

A public cloud refers to a computing service that is offered by third-party providers and is accessible over the public internet. This model is characterized by shared resources, scalability, and pay-per-use pricing. Public cloud services are designed to serve multiple customers, enabling businesses to leverage vast computing resources without the need to invest in and maintain physical hardware.

The platform is typically managed by an external vendor, which handles the underlying infrastructure, such as servers and storage, along with safety and maintenance tasks. Users can access these services anytime and anywhere, as long as they have internet connectivity. This form of cloud computing is especially beneficial for small to medium-sized enterprises that need to optimize costs while accessing state-of-the-art technology and resources without maintaining a large IT infrastructure.

In contrast, a cloud service restricted to specific organizations refers to a private cloud, and a computing service provided over an internal network pertains to on-premises solutions, while resource sharing based on private regulations describes a hybrid model rather than a public cloud.
