Multi-layer design response time calculator

A system for middleware flow assessment, the system comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor prior to completion of an Enterprise Application Integration (EAI) process integrating a front-end application flow with application program interfaces (APIs) and one or more business services flows, cause the system to:
• receive the front-end application flow, wherein the front-end application flow includes at least one call to the one or more business services flows;
• receive the one or more business services flows, wherein each business service flow includes one or more calls to the APIs;
• execute the front-end application flow repeatedly based on one or more conditions;
• execute the one or more business services flows repeatedly based on one or more conditions;
• compile a complete end-to-end flow that includes the front-end application flow and the one or more business services flows, wherein
• 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, and
• the complete end-to-end flow is compiled based, at least in part, on the one or more conditions for the front-end application flow and the one or more conditions for the business services flows;
• and
• automatically construct a projected latency for the complete end-to-end flow by totaling response times for each of the one or more calls to the APIs included in the complete end-to-end flow.

A computer program product for middleware flow assessment, the computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• instructions stored on the non-transitory computer-readable storage medium that, when executed by a processor prior to completion of an Enterprise Application Integration (EAI) process integrating a front-end application flow with application program interfaces (APIs) and one or more business services flows, causes the processor to:
• receive the front-end application flow, wherein the front-end application flow includes at least one call to the one or more business services flows;
• receive the one or more business services flows, wherein each business service flow includes one or more calls to the APIs;
• execute the front-end application flow repeatedly based on one or more conditions;
• execute the one or more business services flows repeatedly based on one or more conditions;
• compile a complete end-to-end flow that includes the front-end application flow and the one or more business services flows, wherein
• 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, and
• the complete end-to-end flow is compiled based, at least in part, on the one or more conditions for the front-end application flow and the one or more conditions for the business services flows;
• and
• automatically construct a projected latency for the complete end-to-end flow by totaling response times for each of the one or more calls to the APIs included in the complete end-to-end flow.
