WRR balancing between EC2 regions with Route53
Route53 introduced a new feature that lets you configure DNS based balancing between EC2 regions. Yes, you heard that right. Between EC2 regions. How does this magic happen? By leveraging a new R53 concept called Weighted Alias resource records, that let you define multiple mappings between your zone apex and your ELBs, as well as assign weights to the mappings.
This works great, but do keep in mind that this is a round robin scheme and may not be suitable for all kinds of apps. This is a great start, and looking forward to more neat stuff from the route53 team. Enjoy :-)
