# On-Prem deployment

> Managing development, staging, and production environments

## Multi-Environment Support

Valmi Value supports multiple environments for development, staging, and production.

## Environment Types

### Development

* **Purpose**: Local development and testing
* **Data**: Test data only
* **Keys**: Development API keys
* **Isolation**: Separate from production

### Staging

* **Purpose**: Pre-production testing
* **Data**: Production-like test data
* **Keys**: Staging API keys
* **Isolation**: Separate from production

### Production

* **Purpose**: Live customer-facing environment
* **Data**: Real customer data
* **Keys**: Production API keys
* **Isolation**: Fully isolated

## Environment Configuration

### Separate Accounts

Use separate Valmi Value accounts for each environment:

* **Development Account**: For development
* **Staging Account**: For staging
* **Production Account**: For production

### Separate API Keys

Use different API keys per environment:

```python theme={null}
import os

# Get key from environment variable
api_key = os.getenv("VALMI_API_KEY")

# Development: VALMI_API_KEY=sk_test_dev_abc123
# Staging: VALMI_API_KEY=sk_test_staging_xyz789
# Production: VALMI_API_KEY=sk_live_prod_def456

value = ValueClient(api_key=api_key)
```

### Separate Agent Keys

Use different agent keys per environment:

```python theme={null}
# Development
agent_key = os.getenv("VALMI_AGENT_KEY_DEV", "agent_dev_abc123")

# Staging
agent_key = os.getenv("VALMI_AGENT_KEY_STAGING", "agent_staging_xyz789")

# Production
agent_key = os.getenv("VALMI_AGENT_KEY_PROD", "agent_prod_def456")

value.send_action(agent_key=agent_key, ...)
```

## Environment Variables

Use environment variables for configuration:

```bash theme={null}
# Development
export VALMI_API_KEY="sk_test_dev_abc123"
export VALMI_AGENT_KEY="agent_dev_abc123"
export VALMI_ENV="development"

# Staging
export VALMI_API_KEY="sk_test_staging_xyz789"
export VALMI_AGENT_KEY="agent_staging_xyz789"
export VALMI_ENV="staging"

# Production
export VALMI_API_KEY="sk_live_prod_def456"
export VALMI_AGENT_KEY="agent_prod_def456"
export VALMI_ENV="production"
```

## Environment Isolation

Environments are fully isolated:

* **Data Isolation**: No data sharing between environments
* **Key Isolation**: Keys only work in their environment
* **Configuration Isolation**: Separate configuration per environment

## Best Practices

* **Separate Accounts**: Use separate accounts for each environment
* **Different Keys**: Use different keys per environment
* **Environment Variables**: Use environment variables for configuration
* **No Production Data in Dev**: Never use production data in development
* **Test in Staging**: Always test in staging before production
* **Document Configuration**: Document environment configuration

## Deployment Workflow

1. **Development**: Develop and test locally
2. **Staging**: Deploy to staging for integration testing
3. **Production**: Deploy to production after staging validation

## Environment Management

Manage environments:

* **Create Environments**: Set up new environments as needed
* **Sync Configuration**: Keep configuration in sync (where appropriate)
* **Monitor Separately**: Monitor each environment independently
* **Rotate Keys**: Rotate keys per environment
