When you want to use CloudFront to distribute your content, you create a distribution and choose the configuration settings you want. For example:
For the current limit on the number of distributions that you can create for each AWS account, see General Quotas on Web Distributions. The number of files that you can serve per distribution is unlimited.
The following table lists the CloudFront actions that you can take to work with distributions and provides links to the corresponding documentation on how to do the actions with the CloudFront console and the CloudFront API.
When you update a distribution by using the UpdateDistribution CloudFront API action, there are more required fields than when you create a distribution by using CreateDistribution. Review the following tables for a summary of the fields that are required for creating and for updating a distribution.
