Key points:

• AWS CloudFront is a Content Distribution Network (CDN) service that accelerates web content delivery, enhances user experience, and provides security and scalability. It adopts a paid-on-demand pricing model, which is economical.
• Setting up CloudFront distributions requires creating an AWS account and an S3 bucket, and then configuring distribution settings, source settings, default cache behavior settings, and DNS records (if required). Once created, be sure to test, monitor and optimize distribution.
• Common pitfalls when using CloudFront include caching issues, SSL certificate management, access control, and source configuration. To avoid these problems, make sure to properly cache control headers, properly manage SSL certificates, properly restrict access, and properly configure your source.

Introduction to AWS CloudFront

AWS CloudFront is a content distribution network (CDN) service provided by Amazon Web Services (AWS). It aims to accelerate the delivery of Web content by caching content such as images, videos, and static files at the global edge location. This reduces latency and improves the overall user experience.

Advantages of AWS CloudFront

Some of the main advantages of using AWS CloudFront include:

• Faster content delivery. CloudFront caches content at the edge, reducing the time it takes for users to access your content.
• Global coverage. With its massive edge location network, CloudFront can deliver content to users around the world with low latency.
• Scalability. CloudFront automatically scales to handle traffic spikes to ensure consistent performance.
• Safety. CloudFront integrates with AWS security services such as AWS Shield and AWS WAF to protect your content from DDoS attacks and other threats.
• Cost and efficient. CloudFront offers a pay-as-you-can-eat pricing model, allowing you to pay for only the data you use.

Set CloudFront Distribution

You need to set two things before you start using CloudFront:

• A AWS account. If you don't have one, please sign up for a free account.
• A S3 bucket containing your website or application files. If you don't have one, follow this guide to create an S3 bucket.

After completing these operations, you can set up CloudFront distribution.

Common Traps

• Caching issues. Make sure you have set up the appropriate cache control header on the S3 object to control how long CloudFront caches content. If you need to update content, create an invalid request to delete cached content from CloudFront edge location.
• SSL Certificate Management. If you want to use a custom domain with CloudFront, you need to configure an SSL certificate. You can use AWS Certificate Manager (ACM) to create free SSL certificates or import existing certificates from third-party providers.
• Access control. To restrict access to your content, you can use a signed URL or a signature cookie. Make sure to configure the appropriate settings in your CloudFront distribution and generate the required keys.
• Source configuration. Make sure your source is configured correctly in the CloudFront distribution. If you are using an S3 bucket as a source, make sure to use the correct bucket domain name and source access ID.

Configuration options for Amazon CloudFront

When setting up CloudFront distribution, you need to consider some important configuration options:

• Caching behavior. Configure cache behavior to control how CloudFront caches and serves content based on request URLs. You can create multiple cache behaviors with different settings for different URL patterns.
• Custom error page. You can configure custom error pages for specific HTTP status codes. This allows you to provide a better user experience when errors occur.
• Geographical restrictions. If you want to restrict access to your content based on your user's geographic location, you can configure geo-restrictions settings in your CloudFront distribution.
• Lambda@Edge. You can use Lambda@Edge to run AWS Lambda functions at CloudFront edge locations. This allows you to customize content delivery and execute serverless functions on servers closer to users.
• Log records. Enable access logs to collect detailed information about each request made to the CloudFront distribution. You can store these logs in an S3 bucket for further analysis.

Conclusion

AWS CloudFront is a powerful CDN service that helps you deliver content to users around the world faster and safer. By following this tutorial and learning about the various configuration options, you can set up a CloudFront distribution that meets your specific needs and improves the overall user experience.
