GSS failover in route53 ¶
Host Zones records ¶
Auto-failover in route53 ¶
We have the two host zone records with type 'failover' and the two healthChecks for primary(us-east-1) and secondary(us-west-1) load balancers.
With health check on both primary and secondary record configured:
- If primary record is unhealthy and secondary record is healthy. Then Route53 name servers will route traffic to secondary record.
- If primary record and secondary record are both unhealthy, Route53 name servers will route traffic to primary record.
- Route53 name servers will auto failback to primary side once the primary record is healthy.
Manual-failover in route53 ¶
We use us-east-2 as the third region. When both regions us-east-1 and us-west-1 are down, we need to configure the third region as secondary to ensure the backend service is running normally.
We only need to configure the BeanStalk url of the third region(gss-micr-VGMM1HOFZ9LI.w5h9d7nhtc.us-east-2.elasticbeanstalk.com) as the secondary record at this time.
