Scenario:
What is Round Robin DNS?
Solution:
Load balancing also known as Round Robin allows you to distribute your server load evenly among multiple servers, handy for load balancing and providing a fault tolerant service.
This is done by creating multiple A records with the same name but different IP values.
For example:
Name | TTL | Type | IP |
---|---|---|---|
www |
1800
|
A
|
10.10.0.1 |
www |
1800
|
A
|
10.10.0.2 |
In this example 50% of the time a user would go to 10.10.0.1 and 50% of the time the user would go to 10.10.0.2.
You can split the traffic between as many as 10 hosts, and server load would be distributed evenly.
