Solution

A Public Cloud is a cloud computing environment that is owned and operated by a third-party cloud provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. These cloud services are made available to the general public or a large industry group and provide resources such as compute power, storage, and networking. The infrastructure is shared among multiple customers, and resources are dynamically allocated based on demand. Public clouds are cost-effective and scalable but may lack the level of control and customization offered by private clouds. Option A (Only accessible to authorized users): This is incorrect. Public clouds are accessible to anyone who subscribes to the cloud provider's services. Option B (Private ownership and operation): This is incorrect. Private clouds are owned and operated by a specific organization for its internal use, not a public cloud. Option D (Full control over hardware): This is incorrect. Public cloud customers do not have direct control over the data center hardware. They only manage the virtual resources they are using. Option E (Primarily for storing data): This is incorrect. Public clouds provide a wide range of services, including computation, networking, and storage, not just data storage.
