Continuous
Creates a continuous deployment policy that routes a subset of production traffic from a primary distribution to a staging distribution. After you create and update a staging distribution, you can use a continuous deployment policy to incrementally move traffic to the staging distribution. This enables you to test changes to a distribution's configuration before moving all of your production traffic to the new configuration. For more information, see Using CloudFront continuous deployment to safely test CDN configuration changes in the Amazon CloudFront Developer Guide.
