Dynamic upstream service selection method and device, equipment and medium

Abstract

The embodiment of the invention provides a dynamic upstream service selection method and device, equipment and a medium. The method comprises the following steps: acquiring an access request and a route matching rule; the upstream service determines an access parameter for a service instance or a server directly processing the access request according to the access request; determining candidate upstream services according to the access parameters and a route matching rule; determining the load condition of the candidate upstream service according to the candidate upstream service; determining a target upstream service according to an access parameter and the load condition of the candidate upstream service; the problems of non-uniform resource allocation, performance bottleneck and lack of dynamic adjustment capability under traditional static configuration are effectively solved, stable and efficient operation of the API gateway in a high-concurrency and diversified request scene is ensured, the overall throughput and response speed of a system are greatly improved, the operation and maintenance cost is reduced, and the service life of the system is prolonged. And the expandability and the flexibility of the system are enhanced.
