OriginGroup
An origin group includes two origins (a primary origin and a secondary origin to failover to) and a failover criteria that you specify. You create an origin group to support origin failover in CloudFront. When you create or update a distribution, you can specify the origin group instead of a single origin, and CloudFront will failover from the primary origin to the secondary origin under the failover conditions that you've chosen.
Optionally, you can choose selection criteria for your origin group to specify how your origins are selected when your distribution routes viewer requests.
