Global cache scenario: Storing state for integrations

You can use a global cache to store state for integrations. With a global cache, each integration server can handle replies, even when the request was processed by another integration server.

When IBM® App Connect Enterprise is used to integrate asynchronous systems, the integration server records information about the requester to correlate the replies correctly, as shown in the following diagram.

When this integration is deployed to multiple integration servers for workload balancing, the reply will not necessarily return through the same integration server as the original request.
