Clustering in the Enterprise Gateway Configuration
You can have multiple Enterprise Gateway Servers and use a third-party product to load balance them. In addition, you can cluster your Internal Servers to improve availability, reliability, and scalability. For more information about Integration Server clustering, see webMethods Integration Server Clustering Guide.
The following diagram illustrates a supported configuration. Keep the following points in mind when working with clustered Internal Servers:
*Each Internal Server must connect to each Enterprise Gateway Server.
*Do not create a cluster of Enterprise Gateway Servers or include them as members of a cluster of “regular” Integration Servers.
