Abstract
Methods, apparatus, and products are disclosed for reliable messaging using redundant message streams in a high speed, low latency data communications environment that include brokering, by a stream administration server, establishment of an active message stream to a subscribing client device from an active feed adapter, the active message stream capable of communicating active application messages; brokering, by the server, establishment of a backup message stream to the subscribing client device from a backup feed adapter, the backup message stream capable of communicating backup application messages representing duplicates of the active messages; receiving the active messages in messaging middleware of the subscribing client device; receiving, in response to a failover, the backup messages in the messaging middleware; and administering, by the messaging middleware, the backup messages in dependence upon an active stream source identifier, an active stream source sequence number, a backup stream source identifier, and a backup stream source sequence number.
