Public Cloud: A public cloud is a cloud computing model where the cloud infrastructure and services are provided by a third-party cloud service provider and made available to the general public over the internet. In a public cloud, multiple users share the same resources, such as servers, storage, and network infrastructure. Users can access the resources they need on a pay-as-you-go basis, and the cloud service provider is responsible for managing and maintaining the infrastructure.
Public cloud services are typically designed to be highly scalable, flexible, and cost-effective. Examples of public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
