Which cloud deployment model exclusively uses dedicated cloud resources for a customer?

  1. Community cloud

  2. Private cloud

  3. Hybrid cloud

  4. Public cloud

The correct answer is: Private cloud

The private cloud deployment model is characterized by its exclusive use of dedicated resources for a single customer or organization. This means that all the cloud infrastructure—servers, storage, networking, and services—is reserved solely for that entity. This model offers the highest level of security and control, as the organization can dictate configurations, security parameters, and compliance to its specific needs without the interference or concerns associated with sharing resources with other entities. In contrast, the community cloud model serves multiple organizations with similar requirements, sharing the infrastructure among a specific group with common concerns. The hybrid cloud model integrates both private and public cloud resources, allowing data and applications to be shared between the two, which does not guarantee dedicated resources. Finally, the public cloud model uses shared resources among many different customers, where infrastructure is not dedicated to a single organization, leading to potential security and privacy concerns. Therefore, the exclusive nature of the private cloud makes it the correct choice for this question.
