  • Publication number: 20240143322
    Abstract: A software developer proxy tool accesses microservice applications for a software development project by connecting the developer proxy tool to a common port on a computer network. The tool implements software and hardware to register a plurality of the microservice applications on connection ports that connect to the developer proxy tool at an address for the common port. Data requests among the microservices are handled by the developer proxy tool via the common port. The tool sequentially queries selected microservice applications on the respective connection ports to determine availability for completing a request. The tool receives responses back from microservices and directs the responses back to the requesting program. Failed requests trigger use of remote or third party microservice applications that may be available over an internet connection.
