Microservices communication pattern for fault detection in end-to-end flows

A system for fault detection in an end-to-end communication flow between microservices within a cloud computing environment, comprising:

• one or more computers with executable instructions that when executed cause the system to:
• establish a communication pattern between an invoking microservice and one or more microservices to enable fault detection of a failure of an end-to-end communication flow between the invoking microservice and the one or more microservices, wherein the communication pattern includes a request to self-monitor for the fault detection by the one or more microservices, and an acknowledgement response provided by the invoking microservice to the one or more microservices indicating success or failure of the end-to-end communication flow between the invoking microservice and the one or more microservices;
• and
• send the acknowledgement response indicating failure or success of the end-to-end communication flow between the invoking microservice and the one or more microservices upon the invoking micro service encountering a failure in the end-to-end flow or determining that the end-to-end flow has completed successfully;
• receive the acknowledgement response, from the invoking microservice, indicating the failure, detecting the failure, and triggering a notification or corrective action;
• receive the acknowledgement response, from the invoking microservice, indicating completion of the end-to-end flow with success, detecting an absence of the failure, or triggering the notification or the corrective action;
• or
• detect a failure and trigger a notification or corrective action upon failing to receive a receipt of the acknowledgement response, from the invoking microservice after a pre-determined timeout period.

A computer program product for, by a processor, fault detection in an end-to-end communication flow between microservices within a cloud computing environment, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions executed by the processor, comprising:

• an executable portion that establishes a communication pattern between an invoking microservice and one or more microservices to enable fault detection of a failure of an end-to-end communication flow between the invoking microservice and the one or more microservices, wherein the communication pattern includes a request to self-monitor for the fault detection by the one or more microservices, and an acknowledgement response provided by the invoking microservice to the one or more microservices indicating success or failure of the end-to-end communication flow between the invoking microservice and the one or more microservices;
• and
• an executable portion that:
• sends the acknowledgement response indicating failure or success of the end-to-end communication flow between the invoking microservice and the one or more microservices upon the invoking micro service encountering a failure in the end-to-end flow or determining that the end-to-end flow has completed successfully;
• receives the acknowledgement response, from the invoking microservice, indicating the failure, detecting the failure, and triggering a notification or corrective action;
• receives the acknowledgement response, from the invoking microservice, indicating completion of the end-to-end flow with success, detecting an absence of the failure, or triggering the notification or the corrective action;
• or
• detects a failure and trigger a notification or corrective action upon failing to receive a receipt of the acknowledgement response, from the invoking microservice after a pre-determined timeout period.
