Which cloud service delivers cloud services over a network that is open for free usage?

The public cloud is characterized by its provision of cloud services over an open network, allowing anyone to access resources without charge. These services are typically owned and managed by third-party cloud providers, who offer a wide range of computing resources, such as storage, applications, and processing power, to the general public.

Public clouds are highly scalable and efficient, making it possible for users to pay only for the resources they consume. They provide a range of services suitable for various needs, from individual developers to large enterprises, which makes them particularly advantageous for projects that can benefit from shared infrastructure.

In contrast, other cloud models, like hybrid, community, and private clouds, do not fit this description. Hybrid clouds combine public and private services, community clouds serve a specific group of organizations with shared concerns, and private clouds are dedicated to a single organization, often involving significantly more overhead costs and restrictions on access.
