In the Mist architecture, an organization is a higher-level entity that can contain multiple sites.

A. A site is contained within an organization:Each site operates under the umbrella of an organization, allowing centralized management and policy enforcement.

B. Multiple sites may be contained within a single organization:This structure enables organizations to manage and monitor different geographical locations or different business units within a single centralized framework.

This hierarchical structure facilitates scalable and organized network management.
