-- | An origin group includes two origins (a primary origin and a second
-- 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 specifiy the origin group
-- instead of a single origin, and CloudFront will failover from the
-- primary origin to the second origin under the failover conditions that
-- you\'ve chosen.
