Global cache scenario: Storing state for integrations
You can use a global cache to store state for integrations. With a global cache, each integration node can handle replies, even when the request was processed by another integration node.
When IBM® Integration Bus is used
to integrate asynchronous systems, the integration node records information
about the requester to correlate the replies correctly, as shown in
the following diagram.
When this integration is deployed to multiple integration nodes for workload balancing, the reply
will not necessarily return through the same integration node as the original
request.
With a global cache, each integration node
can handle replies, even when the request was processed by another
integration node.
