Simple HA/HP clustering Using Only DNS

holviala writes "I cooked up a way to achieve high-availability and high-performance clustering using nothing but a few strangely configured dns zones. In case someone else is interested in an extremely easy clustering solution, I wrote a document about it. It's a bit technical, but the included examples should make it clear for anyone who's used to configuring dns. And yes, the linked site is clustered too, so... ummm... no need to be gentle :-)."

Don't use "Domain.dom". There are well-known domains that are reserved explicitly for this purpose [rfc-editor.org].

As someone who maintains two clusters that run LVS, I'd agree that there's nothing that magical about setting it up. However, for a simple two node cluster LVS is a massive overkill - you've got to have as many director boxes as you have nodes!

I'm not sure I'd use this guy's method, but it's interesting nonetheless.
