Abstract
Systems and methods that allow only a single PSD to be used for a customer regardless of the number of servers in the system are provided. This is accomplished by allowing each server to communicate with the other servers in the system, such that each server can determine which customer PSDs are coupled to each of the other servers. As requests are routed to a first server by the load balancer, if the first server does not have the specific customer's PSD installed, it can determine which server has that customer's PSD and forward the request to that second server. Once the request has been processed by the second server, the response is sent back to the first server that received the request for return to the customer.
