Which cloud model involves sharing resources among multiple customers?

The public cloud model is characterized by the provision of services and resources over the internet, which are made available to multiple customers at the same time. In this model, cloud service providers own and manage the infrastructure, and customers access these resources on a pay-as-you-go basis. The key aspect of the public cloud is that the underlying hardware and software are shared among various organizations, leading to cost efficiency and scalability, as resources can be easily allocated and adjusted based on demand.

In addition, public clouds typically allow for greater flexibility, as customers can quickly scale their services up or down depending on their needs, without the burden of management often associated with private cloud environments. This sharing of resources not only optimizes costs but also enhances collaborative possibilities, as businesses from different sectors can leverage the same infrastructure to innovate and grow.
