• Set billing alerts (optional but recommended)
• Configure spending limits

Creating Your First Distribution

Distribution Types

Static Content Distribution (Recommended for beginners)

• Ideal for: Websites, images, downloads, static assets
• Features: Simple configuration, automatic caching
• Cache TTL: Default 86400 seconds (24 hours)

Video Streaming Distribution

• Ideal for: HLS/DASH live streaming, VOD
• Features: Adaptive bitrate support, low-latency optimization
• Protocols: HLS, DASH, MP4, WebM

Dynamic Content Distribution

• Ideal for: API responses, personalized content
• Features: Origin authentication, custom headers
• Cache: Typically shorter TTL or no-cache

Configuration Steps

1. Click New Distribution
2. Select content type
3. Enter origin information:

- Origin Address: your-server.example.com

- Origin Protocol: HTTP or HTTPS

- Connection: Keep-alive (recommended)

1. Configure cache settings:

- Default TTL: 3600 seconds (1 hour)

- Browser Cache: 300 seconds

- Cache Key: Include query strings (configurable)

1. Review and create

DNS Configuration

CNAME Setup

Once your distribution is created:

1. Copy your CNAME target: xyz123.cdn.Sundun.com
2. Log in to your domain provider
3. Create CNAME record:

- Type: CNAME

- Name: cdn (for cdn.yourdomain.com)

- Value: xyz123.cdn.Sundun.com

- TTL: 3600

DNS Propagation

DNS changes propagate within minutes to hours:

• Check status: nslookup cdn.yourdomain.com
• Full propagation: Up to 48 hours
• Sundun shows status in dashboard

Testing & Verification

Health Check

After DNS propagation, verify:

curl -I https://cdn.yourdomain.com/index.html

Look for:

• HTTP 200 status
• x-Sundun-cache: HIT header (after first request)
• x-Sundun-edge: XX-XX showing edge location

Performance Monitoring

1. Go to Analytics > Performance
2. Check:

- Cache Hit Ratio: Target >80%

- Response Time: Compare vs. origin

- Data Transferred: Confirm bandwidth savings

- Edge Locations: See top performing regions

Optimization Best Practices

Cache Optimization

• Set appropriate TTLs per content type
• Use cache headers from origin: Cache-Control, ETag
• Enable compression for text content
• Purge cache when content changes

Security Setup

• Enable DDoS Protection (default: on)
• Configure WAF Rules: SQL injection, XSS protection
• Set Rate Limiting: 1000 req/sec (default)
• Enable HTTPS: Recommended for all traffic

Monitoring

• Set up email alerts for:

- High error rates (>1% 5xx)

- Traffic spikes

- Cache hit ratio drops

Common Issues

Distribution shows "Pending"

• Creation in progress, usually <5 minutes
• Refresh dashboard

No cache hits (Cache: MISS)

• DNS not propagated yet
• Check CNAME configuration
• Origin headers may prevent caching

Requests timing out

• Verify origin is accessible
• Check firewall/security groups
• Increase timeout setting in distribution
