Which cloud type provides services over a network that is open for free usage?

The public cloud is characterized by the provision of services over the internet that are accessible to anyone, often free of charge or with a pay-as-you-go model. This type of cloud infrastructure allows users to leverage computing resources, storage, and various applications without having to invest in physical hardware or software. Public clouds are typically owned and operated by third-party cloud service providers and are designed to serve multiple customers, often referred to as tenants.

In a public cloud setup, users can take advantage of shared resources while maintaining the flexibility and scalability that cloud computing offers. This openness fosters innovation and collaboration, as users can easily access and utilize the services provided. Many widely-known platforms, such as Google Cloud, Amazon Web Services, and Microsoft Azure, represent the public cloud model by allowing individuals and organizations to access their resources without any upfront infrastructure costs.

The other cloud types, such as hybrid, community, and private clouds, cater to specific needs and require more controlled access or tailored deployment, which goes against the notion of free access that defines the public cloud.
