I currently have two web servers. Each located on different ISP.
Seeing how DNS round robin only provides load balancing and not redundancy,
I wanted to go with another option. I found this article from ‘wight-hat.com ‘that suggested
to put the put the DNS service on each web server. And modify the name servers on the
original DNS server. Name Server 1 will point to Web server 1 and Name Server 2 will point
to Web Server 2. In this Case if the DNS is unable to reach it’s Name Server 1
“Also the Web Server 1” then it will try to contact the Name Server 2 “Also Web Server 2”.
All hosts (A records) will supply the correct IP address to contact the available web server.
Is this a viable option?
What are the pro and cons to doing this?
The article can be found here
PS Web server runs on Windows 2003 IIS 7.0
Thanks in advance
