If you are a mid-sized company with scalability requirements and are seeking a reasonable balance between factors such as cost, performance, and reliability, you can use, as an example, the scenario presented in the following figure.

The preceding figure illustrates a two-site scenario in which a more complex production system is housed at the company headquarters (Site A) with product designers and manufacturing users. Another site, (Site B) is separated from headquarters by a Wide-Area Network (WAN) link and requires using Rendezvous Routing Daemons (RVRDs) to pass Rendezvous messages across a WAN and firewalls. Each target system has its own TIBCO Adapter for deployment on the same LAN.
