What is DNS failover in AWS?

Last updated on September 25, 2022 @ 6:37 pm

DNS failover in AWS is a service that allows you to automatically fail over a DNS server to another AWS instance in the event of an outage. When DNS failover is enabled, your DNS traffic is automatically redirected to the secondary DNS server.

You can also use DNS failover to add extra redundancy to your DNS infrastructure.

If your DNS servers are configured for failover, you can use the AWS Management Console to enable DNS failover. You can also use the AWS Command Line Interface (CLI) to enable DNS failover. To enable DNS failover, you first create an association between your DNS servers and the AWS instance(s) that you want to use as the primary and secondary DNS servers.

Next, you enable DNS failover on the primary DNS server. When you enable DNS failover, the DNS server starts to send all DNS traffic to the secondary DNS server.

There are two ways to use DNS failover:

You can use DNS failover to add extra redundancy to your DNS infrastructure.

PRO TIP: DNS failover in AWS can be used to improve the availability of your website or application.

You can use DNS failover to redirection DNS traffic in the event of an outage.

If you use DNS failover to add extra redundancy to your DNS infrastructure, you can use the AWS Management Console to create a failover group. A failover group is a collection of AWS instances that are configured to fail over to each other in the event of an outage. You can also use the AWS Command Line Interface (CLI) to create a failover group. To create a failover group, you first create an association between your DNS servers and the AWS instance(s) that you want to use as the primary and secondary DNS servers. Next, you create a failover group. A failover group is a collection of DNS servers that are configured to fail over to each other in the event of an outage.

You can also use the AWS Command Line Interface (CLI) to create a failover group.

If you use DNS failover to redirection DNS traffic in the event of an outage, you can use the AWS Management Console to create a DNS redirect rule. A DNS redirect rule allows you to redirect DNS traffic to the secondary DNS server in the event of an outage. You can also use the AWS Command Line Interface (CLI) to create a DNS redirect rule. To create a DNS redirect rule, you first create an association between your DNS servers and the AWS instance(s) that you want to use as the primary and secondary DNS servers. Next, you create a DNS redirect rule.
