AWS::CloudFront::Distribution 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).
