Origin - Amazon CloudFront

Origin

An origin.

An origin is the location where content is stored, and from which CloudFront gets content to serve to viewers. To specify an origin:

  • Use S3OriginConfig to specify an Amazon S3 bucket that is not configured with static website hosting.

  • Use CustomOriginConfig to specify all other kinds of origins, including:

    • An Amazon S3 bucket that is configured with static website hosting

    • An Elastic Load Balancing load balancer

    • An AWS Elemental MediaPackage endpoint

    • An AWS Elemental MediaStore container

    • Any other HTTP server, running on an Amazon EC2 instance or any other kind of host

For the current maximum number of origins that you can specify per distribution, see General Quotas on Web Distributions in the Amazon CloudFront Developer Guide (quotas were formerly referred to as limits).

ConnectionAttempts

The number of times that CloudFront attempts to connect to the origin. The minimum number is 1, the maximum is 3, and the default (if you don’t specify otherwise) is 3.

For a custom origin (including an Amazon S3 bucket that’s configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout.

For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide.
