Hi Chitraj,
We neither received any response.
But we have found a possible solution.
We will implementing something like your implementation, but our planning no is just Catalog,we are involving ServiceDesk, PAM, Unified Self-service too.
For our implementation, we will use a server as load balancer server (already tested in our envioremenet and was successfull).
We followed this 4 steps: https://wiki.ca.com/display/CASM1401/Step%201%20-%20Verify%20Prerequisites%20for%20Clustering
Please, check it out and follow the four steps.
Test it using 2 servers, 1 for the application layer (catalog installed)
And the second one to the load balancer (where you have to configure the above steps)
Write me if you have any further questions.
Regards
