In which cloud model do users have access only to resources within a specific environment?

The private cloud model provides users with access only to resources within a specific environment, which is dedicated to their organization. This environment is not shared with other organizations, offering enhanced privacy and control over the infrastructure and data. Organizations utilizing a private cloud can tailor their resources to meet unique requirements, enabling more stringent security measures, custom applications, and regulatory compliance.

In contrast, the public cloud services are shared among multiple tenants, leading to potential security and privacy concerns as resources are accessible to various users outside a specific organization. Thus, users do not have exclusive control over the environment in the public cloud. The hybrid cloud combines both public and private clouds, allowing for greater flexibility while still involving shared resources. A multitenant cloud typically refers to a scenario where multiple customers share the same physical resources, which again does not provide exclusive access. Therefore, the private cloud is the model that ensures users have access limited to their specific environment.
