Using multiple on-premises webMethods Integration Servers to process requests from webMethods Integration

Multiple on-premises Integration Servers can receive and process requests from webMethods Integration. The on-premises Integration Servers can be in a clustered environment (stateful or stateless) or in a non-clustered environment. When multiple Integration Servers are configured to receive and process requests from webMethods Integration, requests are distributed to each Integration Server in a round-robin fashion.

To use multiple on-premises Integration Servers to process requests from webMethods Integration, the following conditions must be true for all the on-premises Integration Servers:

• Configuration for webMethods Integration tenants, accounts, and applications are the same across all the Integration Servers.
• The packages containing services to be called from webMethods Integration are the same across all Integration Servers. If you change a package on one of the on-premises Integration Servers, you must propagate the changes to the other on-premises Integration Servers.
• Accounts and applications must be uploaded once from one of the Integration Servers, that is, you do not need to upload the accounts and applications from every Integration Server.
• Accounts must be enabled on all Integration Servers to receive and process incoming requests from webMethods Integration.
