Abstract: Systems and methods for managing flow configurable event-driven microservices are disclosed. A system provides, for each function in sequence of steps corresponding to transaction flow associated with model of event-driven microservices, an address of associated memory space using route name. The system connects each function with another function in memory space and/or different application instances with automatic service discovery. The system transports, for event-driven microservices, an input and/or output comprising message and/or an event comprising object corresponding to payload, in an event envelope, based on a configuration file/a configuration file-like handle. Additionally, the system executes a sequence of steps connecting each function in sequential mode or parallel mode, based on a configuration file/a configuration file-like handle.
