If I understand you correctly, you are saying that to handle business
logic processing, I may require X servers. Only a percentage of that
traffic actually requires database processing. if I use a cluster of
application servers against a single database, it will scale better then
if I have to cluster my database, which brings in all sorts of messy
master-master replication issues.
Is this accurate?
