# Cloud Infrastructure Management Platform
|
||
## Software Design Specification (SDS)
|
||
**Version: 1.0 (V1 – Enterprise Foundation)**
|
||
|
||
---
|
||
|
||
## 1. Architectural Overview
|
||
|
||
The platform adopts a Control Plane and Data Plane architecture.
|
||
|
||
- Control Plane manages APIs, identity, orchestration, policy, and state.
|
||
- Data Plane executes infrastructure operations via agents and providers.
|
||
|
||
---
|
||
|
||
## 2. High-Level Components
|
||
|
||
### 2.1 Management Layer
|
||
- Tenant Management Console
|
||
- Provider / Operations Console
|
||
|
||
In Version 1, both consoles MAY be implemented as a single UI with strict role-based access control.
|
||
|
||
---
|
||
|
||
### 2.2 API Gateway
|
||
Responsibilities:
|
||
- Authentication and authorization
|
||
- API namespace separation
|
||
- Request validation and rate limiting
|
||
- Centralized audit logging hook
|
||
|
||
---
|
||
|
||
### 2.3 Core Services
|
||
|
||
| Service | Responsibility |
|
||
|-------|----------------|
|
||
| Identity Service | Users, roles, RBAC |
|
||
| Resource Manager | Projects, quotas, metadata |
|
||
| Compute Service | Virtual machine lifecycle |
|
||
| Network Service | Virtual network management |
|
||
| Storage Service | Volume or object storage |
|
||
| Job Service | Workflow orchestration and retries |
|
||
| Audit Service | Append-only audit logging |
|
||
| Metering Service | Usage aggregation |
|
||
|
||
---
|
||
|
||
## 3. Data Model Overview
|
||
|
||
### Core Entities
|
||
- Organization
|
||
- Project
|
||
- User
|
||
- Role
|
||
- Role Binding
|
||
- Virtual Machine
|
||
- Network
|
||
- Volume / Bucket
|
||
- Job
|
||
- Audit Event
|
||
- Quota
|
||
- Provider
|
||
|
||
### Common Resource Attributes
|
||
```
|
||
id
|
||
organization_id
|
||
project_id
|
||
name
|
||
status
|
||
labels
|
||
provider_reference
|
||
created_at
|
||
updated_at
|
||
```
|
||
|
||

|
||
|
||
## 4. API Design Principles
|
||
|
||
- REST-based APIs
|
||
- Versioned endpoints
|
||
- Clear separation between tenant and provider APIs
|
||
|
||
### Namespace Examples
|
||
- /api/tenant/v1/*
|
||
- /api/ops/v1/*
|
||
- /api/common/v1/*
|
||
|

|
||
|
||
## 5. Job & Workflow Design
|
||
|
||
### Job Lifecycle States
|
||
- PENDING
|
||
- RUNNING
|
||
- SUCCEEDED
|
||
- FAILED
|
||
- RETRYING
|
||
|
||
### Design Characteristics
|
||
- Idempotent create operations
|
||
- Retry for transient failures only
|
||
- Persistent job state storage
|
||
|
||

|
||
|
||
## 6. Provider & Agent Architecture
|
||
|
||
### Provider Interfaces
|
||
- Compute Provider
|
||
- Network Provider
|
||
- Storage Provider
|
||
|
||
### Agent Responsibilities
|
||
- Execute infrastructure-level operations
|
||
- Report actual state to the control plane
|
||
- Emit audit and telemetry data
|
||
|
||
---
|
||
|
||
## 7. Reconciliation Mechanism
|
||
|
||
- Periodic reconciliation loop
|
||
- Desired state vs actual state comparison
|
||
- Drift handling via:
|
||
- Automated correction
|
||
- Operator alert and incident escalation
|
||
|
||
---
|
||
|
||
## 8. Security Architecture
|
||
|
||
- Token-based authentication
|
||
- RBAC enforcement across services
|
||
- Encrypted secret storage
|
||
- Distributed request tracing
|
||
|
||
---
|
||
|
||
## 9. Deployment Model (V1)
|
||
|
||
- Stateless API services
|
||
- PostgreSQL as primary datastore
|
||
- Message queue for job distribution
|
||
- Agent deployment per infrastructure cluster
|
||
|
||
---
|
||
|
||
## 10. Future Evolution
|
||
|
||
- Multi-cluster federation
|
||
- Kubernetes services
|
||
- Policy-as-Code
|
||
- Billing and invoicing
|
||
- Application marketplace
