# Deployment Options for Video Accessibility Platform

## 🏗 Current Docker Setup

Your `docker-compose.yml` serves **both frontend and backend** in **development mode**:

- **Frontend**: Vite dev server on port 5173 (hot reload)
- **Backend**: FastAPI on port 8000 (auto-reload)
- **Database**: MongoDB + Redis
- **Workers**: Celery + Change Stream service

## 🚀 Production Deployment Options

### 1. **All-in-Docker Production** ✅ Recommended

**What it does:**
- Frontend: Built React app served by Nginx (port 80)
- Backend: Production FastAPI (port 8000) 
- Single `docker-compose up` deployment

**Usage:**
```bash
# Production deployment
docker-compose -f docker-compose.prod.yml up -d

# Access:
# Frontend: http://localhost:80
# Backend API: http://localhost:8000
```

**Benefits:**
- ✅ Single command deployment
- ✅ Optimized frontend build
- ✅ Production-ready configuration
- ✅ Built-in health checks
- ✅ Nginx caching and compression

### 2. **Single Domain with Nginx Proxy** ✅ Best UX

**What it does:**
- Everything served from one domain (port 80)
- `/api/*` routes to backend
- `/*` routes to frontend
- WebSocket support included

**Usage:**
```bash
# Uses nginx/nginx.conf for routing
docker-compose -f docker-compose.prod.yml up nginx

# Access everything at: http://localhost
```

**Benefits:**
- ✅ No CORS issues
- ✅ Single domain simplicity
- ✅ Better caching control
- ✅ Rate limiting built-in
- ✅ SSL termination ready

### 3. **Cloud-Native (Google Cloud)** 🌟 Enterprise

**Architecture:**
```
Frontend (Cloud Storage + CDN) → API (Cloud Run) → Database (MongoDB Atlas)
                                      ↓
                               Workers (Cloud Run)
```

**Components:**
- **Frontend**: Build + deploy to Cloud Storage, serve via Cloud CDN
- **Backend**: Deploy to Cloud Run (auto-scaling)
- **Workers**: Separate Cloud Run service for Celery
- **Database**: MongoDB Atlas (managed)
- **Files**: Google Cloud Storage (already integrated)

**Benefits:**
- ✅ Auto-scaling
- ✅ Global CDN
- ✅ Managed services
- ✅ Pay-per-use
- ✅ High availability

## 📊 Comparison Matrix

| Option | Complexity | Cost | Scalability | Maintenance |
|--------|------------|------|-------------|-------------|
| **Dev Docker** | Low | Very Low | Limited | Manual |
| **Prod Docker** | Low | Low | Manual | Medium |
| **Nginx Proxy** | Medium | Low | Manual | Medium |
| **Cloud Native** | High | Variable | Automatic | Low |

## 🚀 Quick Migration Guide

### From Development → Production Docker

1. **Update environment variables:**
   ```bash
   cp .env.example .env.prod
   # Edit .env.prod with production values
   ```

2. **Deploy:**
   ```bash
   docker-compose -f docker-compose.prod.yml up -d
   ```

3. **Verify:**
   ```bash
   # Frontend (optimized build)
   curl http://localhost:80
   
   # Backend API
   curl http://localhost:8000/health
   ```

### From Docker → Cloud Native

1. **Build frontend:**
   ```bash
   cd frontend && npm run build
   gsutil -m rsync -r -d dist/ gs://your-bucket/
   ```

2. **Deploy backend:**
   ```bash
   gcloud run deploy video-api --source=./backend --region=us-central1
   ```

3. **Deploy workers:**
   ```bash
   gcloud run deploy video-workers --source=./backend --region=us-central1
   ```

## 🔧 Configuration Files Created

### `docker-compose.prod.yml`
- Production-ready Docker setup
- Nginx serving frontend
- Optimized environment variables
- Health checks included

### `nginx/nginx.conf`
- Single-domain routing configuration
- API proxy with rate limiting
- WebSocket support
- Static file caching
- Security headers

## 🎯 Recommendations by Use Case

### **Small Team / MVP**
→ Use **Production Docker** (`docker-compose.prod.yml`)

### **Growing Business**
→ Use **Nginx Proxy** setup for better performance

### **Enterprise / Scale**
→ Go **Cloud Native** with Google Cloud Run + CDN

## 🔍 Current Status

✅ **Development**: Already working with `docker-compose up`  
✅ **Production Docker**: Ready with `docker-compose.prod.yml`  
✅ **Nginx Proxy**: Configured and ready to deploy  
⚠️ **Cloud Native**: Requires GCP setup and configuration  

Your current Docker setup is **development-optimized**. For production, use the new `docker-compose.prod.yml` which properly builds and serves the React app through Nginx while keeping the backend API separate but coordinated.
