# Cloud Infrastructure Management Platform
## Software Requirements Specification (SRS)
**Version: 1.0 (V1 – Enterprise Foundation)**

---

## 1. Purpose & Vision

This document defines the Software Requirements Specification (SRS) for the Cloud Infrastructure Management Platform (CIMP).

The platform is designed to deliver enterprise-grade, IaaS-like cloud capabilities inspired by AWS, GCP, and Azure, primarily targeting private and managed cloud environments.

Version 1 focuses on strong architectural foundations, governance, and security, while maintaining a controlled and achievable feature scope.

## 2. Target Users & Roles

### 2.1 Tenant Roles
- Tenant Owner
- Project Admin
- Project Operator
- Project Viewer

### 2.2 Provider / Operator Roles
- Cloud Operator
- Infrastructure Administrator
- Security / Audit Administrator
- Break-glass Super Administrator

---

## 3. Scope Definition

### 3.1 In Scope (V1)
- Multi-tenant and multi-project architecture
- Identity and Access Management (RBAC)
- Compute service (Virtual Machine lifecycle)
- Basic virtual networking
- Basic storage service (block or object)
- Asynchronous job execution
- Audit logging (append-only)
- Usage metering and reporting
- Provider / operations management console

### 3.2 Out of Scope (V1)
- Public cloud federation
- Auto-scaling and elasticity
- Kubernetes and container orchestration
- Application marketplace
- Billing or payment gateway
- Advanced SDN automation (BGP / EVPN)

---

## 4. Functional Requirements

### 4.1 Identity & Access Management
- The system SHALL support Organizations (Tenants), Projects, Users, Roles, and Role Bindings.
- The system SHALL enforce strict separation between tenant and provider scopes.
- The system SHALL use token-based API authentication.
- The system SHOULD be extensible to support external Identity Providers (OIDC).

---

### 4.2 Project & Resource Management
- Tenants SHALL be able to create and manage projects.
- Projects SHALL support quota assignment.
- Every resource SHALL belong to exactly one project.
- All resources SHALL include ownership and lifecycle metadata.

---

### 4.3 Compute Service
- Tenants SHALL be able to create Virtual Machines from predefined images.
- The system SHALL support start, stop, reboot, and delete operations.
- VM provisioning SHALL be asynchronous.
- VM lifecycle states SHALL be exposed through the API.

---

### 4.4 Network Service
- Tenants SHALL be able to create virtual networks per project.
- Virtual networks SHALL enforce isolation between projects.
- Virtual machines SHALL be attachable to one or more virtual networks.

---

### 4.5 Storage Service
- Tenants SHALL be able to create storage volumes or object buckets.
- Storage resources SHALL be attachable to compute resources where applicable.
- Snapshot functionality MAY be supported depending on backend capability.

---

### 4.6 Job & Workflow Management
- All infrastructure-impacting operations SHALL be executed via an asynchronous job system.
- Each job SHALL return a job identifier.
- Job execution status SHALL be queryable.

---

### 4.7 Audit Logging
- The system SHALL record all control-plane actions.
- Audit logs SHALL include actor, action, target resource, timestamp, and result.
- Audit logs SHALL be immutable and append-only.

---

### 4.8 Metering & Reporting
- The system SHALL collect usage metrics for compute, network, and storage.
- Usage reports SHALL be generated per project and tenant.
- Billing integration is out of scope for V1.

---

### 4.9 Provider / Operations Management
- Operators SHALL be able to onboard infrastructure clusters.
- Operators SHALL be able to define global policies and catalogs.
- Operators SHALL have visibility into tenant activities for auditing and troubleshooting.

---

## 5. Non-Functional Requirements

### 5.1 Security
- RBAC enforcement at the API layer.
- Encryption for sensitive data at rest.
- Full auditability of administrative actions.

### 5.2 Availability
- Control plane services SHALL be stateless.
- The system SHALL tolerate service restarts without data loss.

### 5.3 Scalability
- Horizontal scalability for API services.
- Asynchronous processing for long-running tasks.

### 5.4 Maintainability
- Modular service architecture.
- Clear separation between control plane and data plane.
