# Phoenix MVP Control Plane Specification

**Minimum Viable Product (MVP) Definition for Phoenix Operating Model**

This document defines the MVP scope for the Phoenix operating model, including required APIs, data model extensions, implementation priorities, and sovereign government MVP requirements.

---

## Executive Summary

The Phoenix MVP Control Plane provides the minimum set of capabilities required to support sovereign government deployments with the five control planes (Commercial, Tenancy, Subscription, Environment, Content & DevOps). The MVP focuses on core functionality while maintaining the separation of concerns and enabling future expansion.

**MVP Principles:**
- **Core Functionality First**: Essential features for sovereign government deployments
- **Separation of Concerns**: All five control planes included in MVP
- **Sovereign Capabilities**: Support for sovereign, regulated, and air-gapped environments
- **Multi-Region Ready**: Foundation for multi-region deployments
- **Integration Ready**: Integration with existing infrastructure (Proxmox, Kubernetes, Keycloak)
