Final Answer:
The type of cloud model in which all the hardware resources owned by a third-party and shared between multiple tenants is a) Public Cloud.
Step-by-step explanation:
In a Public Cloud model, all the hardware resources are owned by a third-party and shared between multiple tenants. This means that the infrastructure, including servers, storage, and networking components, is provided and maintained by a cloud service provider, and multiple users or organizations share these resources.
Public Clouds operate on a scalable and shared model, offering cost-effectiveness and flexibility to users. This contrasts with Private Clouds, where the infrastructure is dedicated to a single organization, and Hybrid Clouds, which combine elements of both public and private models. Community Clouds are designed for specific groups or communities of users who share common concerns.
Public Clouds facilitate on-demand access to computing resources, allowing organizations to scale their operations without the need for significant upfront investments in hardware. The shared nature of the infrastructure allows for efficient resource utilization and cost distribution among multiple tenants.
In summary, the correct answer is a) Public Cloud, where all hardware resources are owned by a third-party and shared among multiple tenants.
