amazon web services - Route 53 DNS Health Check Possible? -


i'm in process of creating route 53 dns failover direct traffic 2 ec2 zones. obviously, if 1 fails, i'd r53 direct traffic other region.

each region has elb instances being distributed. best way me configure r53 health check? ideally, i'd use dns record elb assigned since amazon may change ip.

however doesn't seem possible. in r53 health check option, select following:

protocol: http ip: ip_address port: 8080 hostname: elb_host_name.amazonaws.com path: /index.html

when use this, url still show ip address instead of dns name. option? don't want resolve elb dns entry , put ip in there. fail if amazon decides switch something.

route 53 natively supports elb internal health check. turn "evaluate target health" on , "associate health check" off , r53 use elb's internal health check.

when setting dns failover elb endpoint, set “evaluate target health” true—you don’t create health check of own endpoint. -- aws blog
