CA Business Service Insight is a multi-tiered application capable of being deployed on any number of servers. The number can range from one (standalone deployment) to many (3-tier, or higher for high availability deployments or for multiple application server instances).
Communications between processes are not always significant in a single server deployment however, once the number of servers increases it becomes more important to understand communications between processes to ensure that they are able to occur and to ensure stable application performance.
Most deployments in corporate environments use the standard 3 tier model, which often encounters firewalls between physical servers for various reasons. This section outlines communications CA Business Service Insight uses. The section details the various communications protocols and ports to enable straightforward configuration of firewalls.
