Custom Origins and S3 Bucket Origins
CloudFront allows users to specify the origins from where it fetches content. These origins can be either custom origins or Amazon S3 bucket origins. A custom origin is an HTTP server, which could be an Amazon EC2 instance, an Elastic Load Balancer, or any other HTTP server hosted outside AWS. S3 bucket origins refer to Amazon S3 buckets that store the content. CloudFront has native integration with Amazon S3, enabling users to configure access, caching behavior and other settings specific to S3. Users can also use multiple origin types within the same distribution, allowing them to serve various types of content from different sources.
Guide: Custom Origins and S3 Bucket Origins in AWS CloudFront
Origin in Amazon CloudFront refers to the server from where your content is delivered to the CloudFront edge locations. There are two types of origins:
1. Custom Origins
2. S3 Bucket Origins
Custom Origins are your own HTTP web servers, from where CloudFront gets your files. It can serve any static, dynamic, or even streamed content via HTTP or HTTPS.
S3 Bucket Origins refer to the Amazon S3 bucket from where CloudFront gets your objects, and it can set permissions to restrict who can access your content.
Importance: Origin settings determine how your content is presented to your users and how it interacts with different CloudFront behaviors. This is crucial for handling large geographically disparate user base while ensuring content security.
Working: It works based on the request by CloudFront. If a requested object is not in the edge location, CloudFront compares the path pattern in the request with path patterns in your cache behaviors to determine whether the request should forward to your S3 bucket or to your custom origin.
Exam Tips: Understanding the difference between Custom Origins and S3 Bucket Origins and their use cases are crucial. Be able to explain how to effectively set up and manage both types. Remember, CloudFront can integrate with both equally. Study the behavior of CloudFront when pulling data from these sources. Make sure for S3 Bucket origins, you are familiar with managing access through IAM roles and bucket policies.
