Last evening I installed ColdFusion 8 for a client and setup two instances outside of the default cfusion for clustering. Gone are the days of MX when one had to access jrunsvc or jrun itself to create a Windows Service for the instance or stop and start the instance via the command line. ColdFusion 7 had these features as well, but I wanted to note ColdFusion 8's continued support of clustering. It is a bugless or for lack of a better term "gotchaless" task that if all ducks are in a row can take minutes to configure in its entirety, including install of ColdFusion, import of legacy CAR file, creation of instances (deployment, etc.), and configuring the cluster.
For those that are looking for CF 8 documentation on clustering ColdFusion it is located here: CF 8 clustering.
I would like to see an updated approach to clustering with CF 8 and BIG IP (hardware load balancers in general). Some of the more advanced topics, are a bit out of date and at this time many companies are upgrading their hardware infrastructure and would benefit from this updated information.
No they are not. I have a question though. What is it that you are storing in App scope that requires synchronization?
There may be a better approach. (DB storage, etc). I look forward to your reply.
