I'm no expert on this yet, and have not run session replication myself, but when I was investigating this, many people warned of very high network traffic for the replication (depending on how large your sessions are).
Also be aware, with a single load balancer on the front end, you still have a single point of failure. Likewise on the database side (which I don't see here). I currently do sticky-sessions behind a load balancer without session replication, and our load gets distributed across both servers. Otherwise, looks like you have the idea's down pat as far as how they will hook together ;) Chris -----Original Message----- From: Steven Wood [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 27, 2008 1:14 PM To: CF-Talk Subject: Please Review CF Cluster Diagram We are inexperienced with ColdFusion clustering, but believe that it would server us well if we started implementing it with our upgrade to CF8. We currently run multi-instance CF7 across 2 production servers... but without clustering. In essence, the servers are mirrors and essentially live backups of each other. They don't really share the load or provide true automatic fail over. Can you take a look at the following diagram to see if we are on the right track here? This is our first stab at how CF instance clustering might work in our environment. http://ooine.com/image/generic_cluster_plan_01.gif Thanks very much!
