Which OpenStack module serves as a policy management framework?

The module that serves as a policy management framework in OpenStack is Congress. Congress is specifically designed to provide a centralized way to manage policy across different OpenStack services. It allows organizations to define and enforce policies that can control aspects like resource usage, access control, and compliance. By using Congress, administrators can create complex rules that govern how resources are allocated and utilized, ensuring that the cloud infrastructure meets specific requirements and governance standards.

In contrast, Neutron primarily deals with networking as a service for OpenStack, managing networks and IP addresses. Ironic focuses on bare metal provisioning, allowing users to manage physical machines instead of virtual instances. Heat is another OpenStack project that provides orchestration services, enabling users to define and manage cloud applications through templates, but it does not specifically address policy management. Thus, Congress stands out as the authoritative module for handling policies within the OpenStack ecosystem.
