Quick Start Guide

Welcome to Sundun CDN. This guide walks you through the essential steps to accelerate your content globally in under 10 minutes.

Prerequisites

Before you begin, ensure you have:

• An active Sundun account
• Access to your domain's DNS settings
• Basic understanding of DNS records (CNAME, A records)
• Your origin server information (IP address or domain)

Step 1: Create Your First Distribution

1. Log in to the Sundun console at dashboard.Sundun.com
2. Navigate to Distributions > Create Distribution
3. Select your content type:

- Static Content: For websites, images, and assets

- Live Video: For HLS/DASH streaming

- Dynamic Content: For applications with origin authentication

Step 2: Configure Your Origin

In the distribution settings, specify where Sundun should pull content from:

Origin Domain: your-api.example.com Origin Protocol: HTTPS (recommended) Origin Port: 443 Host Header: your-api.example.com

For optimal performance:

• Use HTTPS origins for enhanced security
• Enable Origin Shield for additional caching layer
• Set appropriate origin timeouts (30-60 seconds)

Step 3: Update Your DNS Records

Sundun provides a CNAME record for your domain:

1. Copy the provided CNAME target from your distribution settings
2. Log in to your domain registrar
3. Add a CNAME record:

- Name: cdn.yourdomain.com

- Value: [your-distribution-id].cdn.Sundun.com

- TTL: 3600

Wait for DNS propagation (usually 5-30 minutes).

Step 4: Verify Your Setup

Test the connectivity:

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

Expected response:

HTTP/2 200 x-Sundun-cache: HIT x-Sundun-edge: sg-01

Next Steps

• Configure HTTPS/SSL: Set up custom certificates or use auto-provisioned HTTPS
• Set Cache Rules: Define TTL policies based on content type
• Enable Security: Configure DDoS protection and WAF rules
• Monitor Performance: Review analytics in the Sundun console
