Amazon Route 53 Adds Elastic Load Balancer Integration for DNS Failover
刚才整理邮件的时候看到的<p>Dear Amazon Web Services Customer,</p><p>We are excited to announce that Route 53 DNS Failover now supports
Elastic Load Balancing (ELB) endpoints. Starting today, you can use
Route 53’s existing health checking and DNS failover features for
applications running behind an ELB, to increase redundancy and
availability for these apps.</p>
<p>With DNS Failover, Amazon Route 53 can help detect an outage of your
website and redirect your end users to alternate locations where your
application is operating properly. When you enable this feature, Route
53 uses health checks—regularly making Internet requests to your
application’s endpoints from multiple locations around the world—to
determine whether each endpoint of your application is up or down. </p>
<p>For ELB endpoints, Route 53 evaluates the health of the load balancer
itself and the health of your application running on the EC2 instances
behind it. If any part of the stack goes down, Route 53 detects the
failure, routes traffic away from the load balancer, and directs traffic
to other healthy ELB endpoints. Route 53 DNS Failover also supports EC2
endpoints as well as endpoints located in your own datacenter.</p>
<p>Using Route 53 DNS Failover, you can run your primary application
simultaneously in multiple AWS regions around the world. Route 53
automatically removes from service any region where your application is
unavailable. You can also take advantage of a simple backup site hosted
on Amazon Simple Storage Service (Amazon S3), with Route 53 directing
users to this backup site in the event that your application becomes
unavailable.</p>
<p>Health checks of Amazon ELB endpoints are free, and getting started is easy.
