Guide: Understanding the Origin Server in AWS CloudFront
What it is:
The Origin Server in AWS CloudFront is the base location from where the files are served to the Content Delivery Network (CDN). It is where the CloudFront distributions pull the original versions of your files.
Why it is important:
Setting up the right Origin Server is essential to ensure your files are correctly and efficiently delivered through AWS CloudFront. It affects the latency and overall performance of your CDN.
How it works:
When a request hits the CDN, it routes to the nearest edge location, which then connects to the Origin Server to retrieve the original copy of the content (if not cached). The content is subsequently served back to the edge location, which conveys it to the end-user.
Exam Tips: Answering Questions on Origin Server:
1. Understand the role and importance of the origin server in the AWS CloudFront setup.
2. Familiarize yourself with how the content is delivered from the origin server to the edge location and finally to the user.
3. Be aware of different origin server types (like an S3 bucket or HTTP server) and the use cases they fit.
4. Be aware of how to troubleshoot origin server issues - e.g., origin server not found or failover scenarios.
5. Understand the connection between origin settings and cache behaviors.
Note: AWS often uses realistic scenarios to test your application knowledge, so consider the origin server's setup and configuration in different scenarios.

Origin Server practice test
The origin server is the original source of the content to be distributed via AWS CloudFront. It can be an Amazon S3 bucket for storing static files, an EC2 instance or an Elastic Load Balancer for dynamic content, or a custom origin server like a private data center or an on-premise server. The origin server provides content to CloudFront edge locations, which then caches and serves it to the end-users. In CloudFront configurations, you define the origin server and other related parameters, like protocols, connection attempts, and timeouts.
