Failover dns is an automated DNS failover process that can be used to keep your website or network service up and running in case of a server failure. It monitors one of your servers and changes the DNS settings automatically when it detects it's not responding correctly.
dns failover a record
There are a few different methods of using DNS for failover. Some employ a round-robin method, i.e. Many use multiple IP addresses, and remove them if they go down. Others combine this with monitoring.
Round robin DNS is easy to use and is good for smaller sites that don't need much redundancy and have low load. TTLs can be set incorrectly and this will cause problems. The problem with this approach is that when you publish a dead address, a certain percentage of your users will still be connecting to the dead server until the TTL expires.
To prevent this from happening, you need to have a solid understanding of DNS resolvers and how they work. You must also know how to use various DNS recursive algorithmes that are offered by most failover software.
dns failover configuration
To set up failover using DNS, you must create two separate DNS records, one for the primary and another for the backup server or domain. In your failover configuration, you must specify domain names and host names for each record. You can also use host:port list or a name for DNS A records that represents multiple IP address to do this.
dns multiple a records failover
DNS multiple a record failover is exactly the same as DNS Round Robin, except with multiple IPs in each record. This makes it much easier to setup a failover because DNS resolvers can change the DNS settings for a failed IP address when they are aware of a backup.
The dns system must monitor the IP address of the failed server in addition the the monitoring it does internally on the backup address. This type is monitoring is not part of your default DNS configuration. However, you can configure the health check module to add this monitoring.
High availability dns failover
In order to achieve high availability using DNS, it is best to ensure your IP is always accessible from the Internet. This is a crucial step as it ensures that most of your website visitors can access it, even if you lose the primary server.
This can either be done using a DNS record containing a secondary Internet address, or by using an automated web server which changes all DNS records of incoming requests automatically to a specified IP address once it has been determined that the main IP address is not accessible. The system monitors a specific range of addresses and makes the change if it finds that the primary IP is no longer accessible.
