I 've never tried to cluster mysql (never had the need), but a quick
Google of "mysql clustering " reveals a lot. On the front-end, you can
always get by on the cheap using a project like python director
(
http://pythondirector.sourceforge.net/
) or balance
(
http://www.inlab.de/balance.html
). I 'm currently using pydir for load
balancing to a pool of smtp relays, and it works beautifully. Doesn 't
support a lot of the high-end schedulers like those found in commercial
LB products (F5 Big-IP, Cisco Local Director, etc), but works well for
simple load distribution (round-robin, leastconns, etc.).
