Hi Thanks for good articles,I have read Howto about web clustering on "http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-heartbeat-on-debian-lenny-p2" . my question is about sync data on webfarm servers, what solution are there on synchronizing data on backend servers ?? thanks in advanced
You could use rsync or a cluster file system like GlusterFS. Or shared storage like NFS or iSCSI. For databases, use MySQL replication. We have tutorials about each topic here on HowtoForge.
