Creating CloudFront CDN on AWS

Content Delivery Networks (CDN) are an essential component in delivering content efficiently, quickly, and securely to users around the world. Amazon CloudFront is an AWS service that provides a CDN. Here's how you can set up and configure CloudFront on AWS.

Steps/Explanation

1. Create an origin: An origin is the location of your files, such as an Amazon S3 bucket, an EC2 instance, or an on-premise server. You need to select an option for Origin Domain Name when creating a CloudFront Distribution.

2. Create a CloudFront Distribution: A CloudFront distribution is required to enable CloudFront's caching, security, and other features. Go to the CloudFront console and click on "Create Distribution". Then, select your preferred distribution method, either web or RTMP.

3. Configure the CloudFront Distribution settings: You can set up default cache behaviors, customize error pages, configure security, and add restrictions to control access to the distribution. It's important to set up your CloudFront Distribution optimally.

4. Use CloudFront to serve your content: Create a new CNAME in your domain registry, map it to the CloudFront distribution endpoint. Use the new CNAME to request the resources. CloudFront will serve your content.

Examples and Use Cases

• Example: You're running an e-commerce store with frequently changing product images. You need to set up CloudFront to cache your images and serve them to the customers faster. You can create an Amazon S3 bucket as the origin, create a CloudFront Distribution, and configure caching to optimize the distribution of images.

• Use case: You're developing an application that stores videos on an Amazon S3 bucket. You need to optimize video delivery globally while protecting against content piracy. Using CloudFront, you can set up a secure and reliable content delivery network.
