Interior Server and Gateway Server Architecture
TIBCO BusinessConnect Interior Server is the server on which TIBCO BusinessConnect is installed on top of the other required TIBCO software products: TIBCO Runtime Agent, and TIBCO Administrator.
Multiple Interior Servers can work as a cluster to achieve load balancing and fault tolerance. For a list of all required TIBCO and other third-party software products, see TIBCO BusinessConnect™ Installation and Configuration, Installation Requirements.
TIBCO BusinessConnect Gateway Server is located in the demilitarized zone (DMZ), and functions as the front gate by receiving the inbound transactions from trading partners. It is installed by its own, and does not rely on TIBCO Runtime Agent or TIBCO Administrator. Multiple Gateway Servers can work together for load balancing.
The following diagram explains the Gateway Server and Interior Server communications.
