## PART 5: FLY.IO RESOURCE OPTIMIZATION

### Memory Optimization for Go

**Problem**: 256MB RAM is tight for Go

**Solutions**:

**1. Optimize Go Binary**:
```bash
# Reduce binary size
go build -ldflags="-s -w" -o app

# Use UPX compression
upx --best --lzma app
```

**2. Use Lightweight Dependencies**:
- ✅ gqlgen (lightweight GraphQL)
- ✅ Echo (lightweight web framework)
- ✅ GORM (lightweight ORM)

**3. Monitor Memory Usage**:
```bash
# Check memory usage
fly ssh console
free -h
```

**4. Scale to Multiple VMs**:
```bash
# Use 2-3 VMs for better performance
fly scale vm shared-cpu-1x --count 2
```

### Storage Optimization

**Problem**: 3GB storage is limited

**Solutions**:

**1. Use Supabase Storage**:
- ✅ File uploads go to Supabase
- ✅ Not stored on Fly.io
- ✅ Unlimited storage (freemium)

**2. Use Upstash for Cache**:
- ✅ Cache stored in Upstash
- ✅ Not stored on Fly.io
- ✅ Unlimited cache (freemium)

**3. Use PostgreSQL on Supabase**:
- ✅ Database on Supabase
- ✅ Not stored on Fly.io
- ✅ 500MB storage (freemium)

# Set environment variables
fly secrets set WORKOS_API_KEY=sk_...
fly secrets set WORKOS_CLIENT_ID=project_...
fly secrets set SUPABASE_URL=https://...
fly secrets set SUPABASE_KEY=...
```

### Step 3: Deploy Go Backend

```bash
# Create Dockerfile
cat > Dockerfile << 'EOF'
FROM golang:1.23-alpine AS builder
WORKDIR /app
COPY . .
RUN go build -ldflags="-s -w" -o app

FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /app/app .
EXPOSE 8080
CMD ["./app"]
EOF

# Deploy
fly deploy
```

### Step 4: Monitor

```bash
# Check logs
fly logs

# Check status
fly status

# Check resources
fly ssh console
free -h
```
