Current System Overview

The Application is developed on Struts Framework on SunOne Web Server (can be changed if need arises).

The HTTP request from the clients reaches the Application which in turn generates multiple thread requests.

The threads are of variable nature requiring having different resource requirements to execute.

Objective to be Achieved

• Fault tolerant cluster at the Application Level and the Thread Execution Level with seamless failover, preferably with no session loss.
• Load Balancing of the Application
• Load Balancing of the Thread Execution Server based on
o Weight utilization of the respective Thread Server (CPU and Memory)
o Thread utilization of the respective Server
o Balanced routing of similar threads (e.g., 10 identical threads get equally executed in 2 numbers each is there are 5 servers)
In case of conflicts of the load balancing algorithms, the priority will be set as per the above order.
• A Virtual Thread Pool has to be generated in Thread Execution Cluster with queuing analysis

Please let know what analysis results are required for recommending solutions.

Hello

For your needs, I would suggest a 10 server private shelf with a load balancer. It would work slightly different than your schematic, as the single load balancer should be able to take care of both parts. For more information, I would suggest you contact custom.orders@ev1servers.net to fully flesh out a quote.
