描述

I think that there's a mistake in https://github.com/open-guides/og-aws/raw/master/figures/aws-data-transfer-costs.png

It indicates that cross-AZ traffic between ALB/CLB and EC2 is $0.01/GB, but I think it should be 0 (at least for the CLB)

From http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-disable-crosszone-lb.html:

When you enable cross-zone load balancing, you are not charged for data transfer between the load balancer nodes and the instances

I couldn't find the same kind of clear language in the ALB docs though

研究方向
Check the AWS documentation links provided in the issue to verify the cross AZ data transfer cost for ALB and CLB. Update the figure 'aws data transfer costs.png' or add a note clarifying that cross AZ traffic between CLB and EC2 is free. Refer to the existing comments for any additional clarifications.
