Finally, another way to perform the blue-green switch with Route53 is using Weighted Round-Robin. This works for both regular resource record sets as well as alias resource record sets. You have to associate multiple answers for the same domain/sub-domainand assign a weight between 0-255 to each entry. When processing a DNS query,Route53 will select one answer using a probability calculated based on those weights. To perform the blue-green switch you need to have an existing entry for the current “blue” environment with weight 255 and a new entry for the “green” environment with weight 0. Then, simply swap those weights to redirect traffic from blue to green.
