i'd say that figure may be a little high, but i agree with your
sentiment. you could "easily" create a web server cluster by putting
your httpd nodes behind a software load balancer (a BSD box running
PF/CARP or somesuch solution), and you would have created a cluster of
web servers that will provide you with a reasonable amount of
redundancy. this will provide one form of clustering.
granted, this is just one type of clustering computers together -
which is much differnet than say building a farm of machines to
compute data in unison.
