Let's look at Route53. AWS service number four on our high availability top 10. Route53 is a highly available domain name service offered by AWS. It supports geographical routing based on an end user's location. It also provides a DNS failover feature which can redirect users to an alternate location if there's an outage. It accomplishes this with health checks that monitor end points. Route53 makes it easy to perform a graceful application failover from a dynamic site, accessible using an elastic load balancer, pointing to a static S3 base site, and that's a common use case. Companies can also run multi-region systems using the location based routing functionality to send users to a region closest to them. You can also use the weighted routing to divide traffic to different resources based on percentages. Latency routing will direct users to the lowest latency availability zone. You can use weighted routing to collect users' data or perform blue-green deployments. Route53 health checking and DNS failover proves the availability of applications running behind elastic load balancers. You can run applications in multiple AWS regions and designate alternate load balancers for failover cross regions. In the event that your application is unresponsive, Route53 will remove the unavailable load balancer end point from service and direct traffic to an alternate load balancer in another region.
