This application discloses a decentralization processing method, which are applied to a microservice system. A first communication proxy in the microservice system receives a first microservice request sent by a first microservice application, the first communication proxy determines, based on a target control plane rule, a microservice access address corresponding to the first microservice request, and sends the first microservice request to the second communication proxy having the microservice access address, where the second communication proxy is used to forward the first microservice request to the second microservice application. The first communication proxy can send the microservice request to the corresponding second communication proxy, and a control plane does not need to route the microservice request, so that traffic for routing the microservice request by the control plane is effectively reduced, and impact of a burst of microservice requests on the control plane is effectively avoided.
