Methods, systems, and computer program products for integrating front-end applications with application program interfaces (APIs) and middleware business services. A front-end application flow, including at least one call to one or more business services flows, and one or more business services flows, each including one or more calls to application program interfaces (APIs), are received at a processor and the processor compiles a complete end-to-end flow that includes the front-end application flow and the one or more business services flows. The complete end-to-end flow is expressed in ordered terms of the one or more business services flows and the one or more calls to the APIs. A projected latency for the complete end-to-end flow is automatically constructed by the processor by totaling response times for each of the one or more calls to the APIs included in the complete end-to-end flow.

System and method of sequencing distributed asynchronous messages. An inbound handler receives an incoming message with a sequence correlation value that identifies a sequence comprising the incoming message, and checks for a sequence status of the sequence. If the sequence status indicates that none of multiple outbound handlers is currently processing a message for the sequence and if the incoming message is the next message to be processed for the sequence, then the incoming message is forwarded to a queue storage and subsequently forwarded to an available outbound handler. If the sequence status indicates that at least one of the outbound handlers is currently processing a message of the sequence, if the queue storage already comprises a message to be processed for the sequence, or if the incoming message is not the next message to be processed for the sequence, then the incoming message is stored in overflow storage.
