# Enterprise Features

Raxol provides comprehensive enterprise features for building production-ready applications that can scale from small teams to large organizations.

## Overview

Raxol's enterprise features enable you to:
- Deploy secure, authenticated applications
- Monitor and track application performance
- Scale horizontally across multiple nodes
- Integrate with existing enterprise infrastructure

## Quick Start

### Basic Enterprise Setup

```elixir
# config/config.exs
config :raxol,
  # Enable enterprise features
  enterprise: true,
  
  # Authentication
  auth: [
    provider: :database,  # or :ldap, :oauth2, :saml
    session_timeout: 3600,
    mfa_enabled: true
  ],
  
  # Monitoring
  telemetry: [
    backend: :prometheus,
    metrics_port: 9090
  ],
  
  # Security
  security: [
    encrypt_at_rest: true,
    audit_logging: true,
    rate_limiting: true
  ]
```

### Minimal Authentication Example

```elixir
defmodule MyApp.SecureTerminal do
  use Raxol.Enterprise.AuthenticatedApp
  
  @impl true
  def authenticate(credentials) do
    # Your authentication logic
    case MyApp.Auth.verify_user(credentials) do
      {:ok, user} -> {:ok, user}
      {:error, _} -> {:error, :unauthorized}
    end
  end
  
  @impl true
  def authorize(user, resource, action) do
    # Your authorization logic
    MyApp.Auth.can?(user, action, resource)
  end
  
  @impl true
  def render(assigns) do
    # Only authenticated users can see this
    {:box, [border: :double],
      [
        {:text, [], "Welcome #{assigns.current_user.name}!"},
        {:text, [], "Role: #{assigns.current_user.role}"}
      ]
    }
  end
end
```

## Integration Examples

### LDAP Authentication

```elixir
config :raxol, :auth,
  provider: :ldap,
  ldap: [
    host: "ldap.company.com",
    port: 636,
    ssl: true,
    base_dn: "dc=company,dc=com",
    bind_dn: "cn=admin,dc=company,dc=com",
    bind_password: {:system, "LDAP_BIND_PASSWORD"}
  ]
```

### Prometheus Metrics

```elixir
# Automatic metrics collection
defmodule MyApp.Metrics do
  use Raxol.Enterprise.Metrics
  
  def custom_metrics do
    [
      counter("terminal_sessions_total"),
      histogram("command_execution_time"),
      gauge("active_users")
    ]
  end
end
```

### Kubernetes Deployment

```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: raxol-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: raxol
  template:
    metadata:
      labels:
        app: raxol
    spec:
      containers:
      - name: raxol
        image: myapp/raxol:latest
        ports:
        - containerPort: 4000
        env:
        - name: RELEASE_COOKIE
          valueFrom:
            secretKeyRef:
              name: raxol-secrets
              key: cookie
```

## Best Practices

1. **Start Small**: Begin with basic auth and gradually add features
2. **Monitor Early**: Set up metrics from day one
3. **Security First**: Enable audit logging and encryption
4. **Plan for Scale**: Design with horizontal scaling in mind
5. **Automate Deployment**: Use CI/CD pipelines
