Which cloud deployment model offers shared infrastructure and data access limitations?

1. Hybrid

2. Private

3. Public

4. Dedicated

The correct answer is: Public

The public cloud deployment model is characterized by shared infrastructure, where cloud resources are owned and operated by a third-party cloud service provider and made available to multiple organizations or individuals over the internet. In this model, resources such as servers and storage are shared among various users, which can lead to cost savings due to the economies of scale that the provider can achieve. Data access limitations in a public cloud environment are typically managed through various access controls and security measures implemented by the cloud service provider. Users can configure permissions to ensure that sensitive data is only accessible to the intended parties, despite the shared nature of the underlying infrastructure. In contrast, the other deployment models, such as hybrid cloud, private cloud, and dedicated cloud, do not primarily focus on shared infrastructure. A hybrid cloud combines both public and private resources, providing flexibility but not the exclusive shared nature. A private cloud is used by a single organization, offering higher control and security without sharing infrastructures with other entities. A dedicated cloud model also provides exclusive access to an infrastructure but is reserved for a single customer rather than being shared like a public cloud environment.
