recording a correspondence between the publishing IP address and the publishing port and an IP address and a port that are of a physical server hosting the service;
publishing the service;
receiving, by the cloud platform, a service application request from a virtual machine, and
sending a NAT (network address translation) rule to an access network element of the virtual machine, wherein the NAT rule comprises the correspondence between the publishing IP address and the publishing port and the IP address and the port of the physical server hosting the service;
receiving, by the access network element, a service access request from the virtual machine, wherein a destination address of the service access request includes the publishing IP address and the publishing port corresponding to the service;
replacing, by the access network element according to the NAT rule, the destination address of the service access request with the IP address and the port of the physical server;
routing the modified service access request to the physical server;
receiving, by the access network element, a service response message from the physical server; and
sending the service response message to the virtual machine.
