Creating a CloudFront Distribution
Amazon CloudFront is a content delivery service (CDN). In Amazon CloudFront, the content is organized into distributions.
Each distribution has a unique cloudfront.net domain name (e.g. cdn123.cloudfront.net) that can be used to reference objects through the global network of edge locations.
To use Amazon CloudFront:
- Store the original versions of your files on one or more origin servers. An origin server is the location of the definitive version of an object. Origin servers could be an Amazon S3 bucket, an Amazon EC2 instance, an Elastic Load Balancer, or another remote server.
- Create a distribution to register the origin servers with Amazon CloudFront.
- Use your distribution’s domain name in your web pages, media player, or application. When end users request an object using this domain name, they are automatically routed to the nearest edge location for high-performance delivery of your content.
1. In the AWS Management Console, click Services, enter CloudFront, and click the CloudFront result:
2. To start creating a CloudFront distribution, click Create Distribution:
A two-step wizard will load.
3. In the Web section, click Get Started:
This page of the wizard has three sections:
- Origin Settings
- Default Cache Behavior Settings
- Distribution Settings
4. Under Origin Settings, in the Origin Domain Name drop-down, select the S3 bucket you created in the previous lab step:
Leave all other fields in this and the Default Cache Behavior Settings section at their default.
5. Scroll down to Distribution Settings, and in the Price Class drop-down, select Use Only U.S., Canada and Europe:
Amazon CloudFront minimizes end-user latency by delivering content from its entire global network of edge locations. Price Classes let you reduce your delivery prices by excluding Amazon CloudFront’s more expensive edge locations from your Amazon CloudFront distribution. In these cases, Amazon CloudFront will deliver your content from edge locations within the locations in the price class you selected and charge you the data transfer and request pricing from the actual location where the content was delivered.
The time required for deploying a new CloudFront distribution also depends on the number of selected Edge Locations. Selecting all edge locations will take longer to deploy.
6. In the Default Root Object field, enter gallery/index.html:
CloudFront will serve the Default Root Object when the base distribution URL is requested.
7. To finish configuring your distribution, at the bottom of the page, click Create Distribution:
CloudFront immediately assigns an ID and a Domain Name to the distribution and starts updating the edge locations to serve your content:
Observe the status field, after two to three minutes, this field will change from In Progress to Deployed.
You don't need to wait for it, you can proceed to the next lab step now.
In this lab step, you configured and created a CloudFront distribution.
A CloudFront distribution returns a status code of 200 when visited
