- Compression status
- Encryption status
- Validation status
- Retention period
- Storage location

**Validation Rules**:
- All archives must be encrypted

- Must include database consistency checks

### Monitoring Metric

**Description**: Performance and health data points collected from all infrastructure components  
**Key Attributes**:
- Metric ID (unique identifier)

- Alert status
- Aggregation rules

**Validation Rules**:
- All services must expose health metrics
- Critical metrics must have alert thresholds
- Data retention: 90 days detailed, 1 year aggregated
- Metrics must include CPU, memory, disk, network

### Security Policy

**Description**: Container hardening rules and compliance requirements for all deployments  
**Key Attributes**:
- Policy ID (unique identifier)
- Policy type (user, capabilities, filesystem)
- Rule definitions
- Applicable services
- Compliance status
- Violation tracking
- Remediation procedures

**Validation Rules**:
- All containers must run with non-root users
- All containers must drop unnecessary capabilities
- All containers must use read-only filesystems where possible
- All containers must have security options defined

### Deployment Environment

**Description**: Isolated runtime spaces with consistent configurations  
**Key Attributes**:
- Environment ID (unique identifier)
- Environment type (blue/green)
- Service instances
- Network configuration
- Storage configuration
- Access controls
- Deployment status
- Health status

**Validation Rules**:
- Blue and green environments must be identical
- Network isolation between environments
- Consistent configuration across environments
- Automated health checks required
- Traffic switching must be atomic

### Alert Rule

**Description**: Threshold-based conditions that trigger notifications when system metrics exceed limits  
**Key Attributes**:
- Rule ID (unique identifier)
- Metric source
- Threshold conditions
- Severity levels
- Notification channels
- Escalation rules
- Suppression rules
- Acknowledgment status

**Validation Rules**:
- All critical services must have alert rules
- Alert response time must be < 30 seconds
- Must include escalation paths
- Must define recovery procedures
- Regular alert testing required

### Secret Configuration

**Description**: Sensitive information managed outside version control  
**Key Attributes**:
- Secret ID (unique identifier)
- Secret type (password, key, certificate)
- Usage context
- Access controls
- Rotation schedule
- Expiration date
- Compliance requirements

**Validation Rules**:
- No secrets in version control
- All secrets must be encrypted at rest
- Access must be role-based
- Regular rotation required
- Audit trail for all access

### Service Instance

**Description**: Running container with specific configuration and health status  
**Key Attributes**:
- Instance ID (unique identifier)
- Service name and version
- Container configuration
- Resource allocation
- Health status
- Start time
- Network endpoints
- Log configuration

**Validation Rules**:
- All instances must have health checks
- Resource limits must be enforced
- Restart policies must be defined
- Log aggregation must be configured
- Performance monitoring required

### Infrastructure Change

**Description**: Version-controlled modification to system configuration or deployment  
**Key Attributes**:
- Change ID (unique identifier)
- Change type (configuration, deployment, security)
- Description and rationale
- Approval status
- Implementation status
- Rollback plan
- Impact assessment
- Compliance validation

**Validation Rules**:
- All changes must be version-controlled
- Changes require approval before production
- Rollback plans must be tested
- Impact assessment required
- Compliance validation mandatory

### Recovery Point

**Description**: Validated backup state that can be restored for disaster recovery  
**Key Attributes**:
- Recovery point ID (unique identifier)
- Archive reference
- Validation status
- Recovery time objective
- Recovery procedures
- Test results
- Dependencies

**Validation Rules**:
- All recovery points must be tested
- RTO must be < 4 hours
- Recovery procedures must be documented
- Regular testing required
- Success rate must be > 95%

## State Transitions

### Deployment Lifecycle
```
Planned -> In Progress -> Testing -> Live -> Decommissioned
```

### Backup Lifecycle
```
Scheduled -> In Progress -> Completed -> Validated -> Expired
```

### Alert Lifecycle
```
Triggered -> Acknowledged -> Resolved -> Closed
```

### Change Management
```
Requested -> Approved -> Implemented -> Validated -> Closed
```

## Relationships

- **Environment** contains many **Service Instances**
- **Service Instance** generates **Monitoring Metrics**
- **Backup Archive** contains data from **Service Instances**
- **Alert Rule** monitors **Monitoring Metrics**
- **Security Policy** applies to **Service Instances**
- **Infrastructure Change** modifies **Deployment Environments**
- **Recovery Point** references **Backup Archive**
- **Secret Configuration** used by **Service Instances**

## Data Integrity Constraints

- All entities must have unique identifiers
- All timestamps must be UTC
- All audit fields must be immutable
- Foreign key relationships must be validated
- All sensitive data must be encrypted
- All changes must be auditable
