These "tools" will never be outside > our > control (ie not on partners servers) and won't be individually > customised outside some basic settings (no forking of the code) > OK > I'll only have two ColdFusion 8 Enterprise server boxes to do this > (plus separate DB servers), at least to start with. > either > - I run all the customers out of one instance of the application and > use their OrganisationID to differentiate each partner - sometimes > right down to the individual database row level, all in one db. > - cluster both boxes and add a hardware load balancer in front of > them > - additional partners means adding another server into the cluster > - I gain on fail-over but lose on application design. > or > - I run each partner as a seperate CF8 instance off the same > codebase, forget about the OrganisationID, and use each instance's > CFIDE to point the DSN to the corresponding matching database - one > for each partner > - don't bother clustering but try and spread the load by grouping > customers > - additional customers means adding another server to put the new > customers on > - I have no fail-over but it's a lot cleaner as far as rolling out > new customers. > any other options? > any suggestions? > many thanks > b
