Hi All,

I am planning to use Apache/DX server for clustering, and will have 3 webservers, should I mention all the 3 instances of the server in the deployment diagram, Please clarify.

Thanks

You need to clearly show, how would the instances be clustered and session will be migrated. Are you planning multiple instances of server within same hardware box or 3 different hardware boxes with one instance of server software in each of them? You should explain how would the load balancing and failover be taken care at each layer (web, app & DB).
 
It is sorta covered in the JavaRanch Style Guide.
