Failover DNS automates the DNS failover process to ensure that your website and network services remain up and operational in case of server failure. It works by monitoring the availability of one of your server and changing the DNS settings if that server does not respond properly.
The record dns failure
You can use DNS in a number of different ways. Some use a round robin approach, i.e. Many use multiple IP addresses, and remove them if they go down. Others combine this with monitoring.
DNS round robin can be very simple. It works best for small sites with low traffic and little redundancy. TTL settings are important and should be done carefully. The problem with using this method is that even if you publish an address which has expired, some of your users may still connect to it until the TTL expires.
In order to prevent this, you must have a good understanding of how DNS resolvers work and how to configure them. You also need to know how the DNS recursive software works.
dns failover configuration
If you want to use DNS for failover, then you need to create 2 separate DNS records. Create one DNS record for the main server and another DNS record for the secondary domain or backup server. In the failover configuration you will need to specify both domain and host names. This can be done using a list of host:port pairs or a DNS record name representing multiple IP addresses.
Multiple a record failover dns
DNS multiple-a records failover works the same way as DNS round-robin but includes multiple IP addresses per record. This makes setting up a failover easier, as DNS resolvers are more likely to be able to alter the DNS settings if they have a back-up.
In order to ensure a successful dns switchover, the system will need to monitor the IP of the failed address in addition. This type does not appear in the default DNS configuration. You can however add it by configuring your DNS account's health checks module.
High availability DNS failover
It is important to make sure that you can always reach your IP address from the Internet. It is important to ensure that you can reach your site even when the primary server goes down.
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 does this by monitoring a specified range of IP addresses and making the change when it determines that the primary IP address is no longer reachable.
FAQ
What is a responsive design web design?
Responsive Web Design is a method of designing responsive websites. It allows content to display on all devices (desktop computers, tablets and smartphones), so that it can be viewed easily on any device. This allows visitors to view the website on one device and access other features like buttons, navigation menus, etc. RWD aims to ensure that every user who views a site is able to view it on any screen size.
For example, if you were building a website for a company whose products sell primarily through eCommerce, you would want to ensure that even if a customer viewed your website on a smartphone, they could easily purchase items from your store.
A responsive website will adapt its layout to suit the device it is being viewed on. So, viewing the site on your laptop will look like a standard desktop website. However, if you're viewing the page on your phone, it will display differently.
