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 :-)

Mapping zone apex to your ELB with Route53

This blog post is outdated. Route53 has since released new features and Ylastic has integrated them. Please check these posts for the updates:

 

AWS just released a nice feature named zone apex association for mapping the apex of your hosted zone in Route 53 with an elastic load balancer. No more jumping through various hoops and redirects to make queries for a domain such as xanthe.us resolve to your wonderful ELB in EC2. The magic all happens using the concept of Alias Resource Record Sets, which are aliases that point to DNS names in any Route 53 hosted zone. And here's how easy it is to set it up with Ylastic.
