I have to disagree with the author. I have setup Wordpress using OpsWorks and it is a much better way to do this especially considering all of the stack can be auto managed via Chef. Updates are handled automatically and if you get a surge of traffic, autoscale kicks in.

The only issue is getting the plugins to auto update on all of the servers, which I am fairly certain you can do with Chef or WordPress just handles it.
