	//   manually or automatically.
	//   - Mean - Use the average of the traffic across the group. This is a good
	//   choice for resources that share traffic uniformly. Examples include accelerators
	//   and load balancers.
	//   - Max - Use the highest traffic from each resource. This is useful for
	//   resources that don't share traffic and for resources that share that traffic in
	//   a non-uniform way. Examples include Amazon CloudFront distributions and origin
	//   resources for CloudFront distributions.
