• Intelligent Routing: Achieve optimal global traffic scheduling through edge computing technology.
• Full - Site Acceleration: Provide comprehensive acceleration for the entire website, including static resources and dynamic content.
• Security Protection: Incorporate multiple security mechanisms such as DDoS protection and Web Application Firewall (WAF).

📋 Use Cases

1. Static Resource Acceleration: Offer global acceleration services for static files like images, videos, and JavaScript.
2. Dynamic Content Distribution: Quickly cache and distribute dynamic data such as database query results and API responses.
3. Real - Time Log Analysis: Monitor application performance and user behavior in real - time through the edge logging system.

📈 Product Advantages

• Low Latency: With global node coverage, ensure users access content from nearby nodes, reducing network latency.
• High Availability: The multi - active architecture design guarantees uninterrupted service.
• Flexible Scalability: Automatically scale up or down as needed to adapt to business traffic fluctuations.

🚀 Quick Start

Functional Features

• Edge Computing: Execute computing tasks at edge nodes close to users to improve processing efficiency.
• Caching Strategies: Support operations such as intelligent caching and manual refresh to optimize resource utilization.
• Logging and Monitoring: Provide detailed access logs and real - time monitoring panels for operations analysis.

Product Architecture

Fastly's architecture is based on the following core components:

1. Edge Network: A global network of CDN nodes responsible for content storage and distribution.
2. Control Plane: Unified management of the configuration and policies of all edge nodes.
3. Logging System: Real - time collection and analysis of log data from edge nodes.

Applicable Scenarios

• Web Application Acceleration: Improve website loading speed and enhance the user experience.
• API Acceleration: Optimize API response time and improve service performance.
• Video Streaming: Support high - definition video live streaming and on - demand playback to ensure smooth viewing.

💡 Best Practices

Onboarding Guide

1. Register an Account: Visit the Fastly official website (https://www.fastly.com) to complete the registration process.
2. Get an API Key: Generate an API access key in the console for subsequent automated operations.
3. Configure a Domain Name: Add the domain name to be accelerated and configure the CNAME to point to Fastly's CDN service.
4. Deploy the Application: Host static resources on Fastly or configure dynamic content through reverse proxy.

Advanced Features

Edge Computing

Fastly provides the Compute@Edge service, allowing developers to run custom code on edge nodes to implement functions such as real - time data analysis and geographical location determination. For example:

• User Behavior Analysis: Determine the user's region based on the request header information and optimize resource distribution accordingly.
• Dynamic Content Generation: Generate personalized page content based on real - time data.

Web Application Firewall (WAF)

Fastly's WAF service can effectively defend against common web attacks such as SQL injection and XSS. The configuration steps are as follows:

1. Enable the WAF function in the console.
2. Configure security policies, either by selecting predefined rule sets or customizing protection rules.
3. Apply the policies to the target service and monitor the protection effect in real - time.

A/B Testing

With Fastly's edge computing capabilities, A/B testing can be easily implemented:

1. Write routing logic in Compute@Edge to distribute user traffic proportionally to different versions of the backend services.
2. Monitor the performance indicators of each version in real - time, such as response time and error rate.
3. Decide whether to fully promote a certain version based on the data analysis results.

💻 Usage Examples

Configuring a Domain Name

// Add a new domain name in the Fastly console
const domain = {
  name: 'your-domain.com',
  zone_id: '12345',
  type: 'CNAME',
  ttl: 'automatic'
};
fastly.createDomain(domain);

Enabling Caching

// Configure the default caching policy
const cachingBehavior = {
  name: 'default_cache_behavior',
  ttl: '3600',
  mode: 'cache_only'
};
fastly.updateSettings({ caching_behaviors: [cachingBehavior] });

Edge Computing

// Process request header information at the edge node
function handleRequest(request) {
  const geo = getGeolocation(request);
  if (geo.country === 'US') {
    serveStaticResource();
  } else {
    redirect('/');
  }
}
