METHOD FOR VIRTUAL MACHINE TO ACCESS PHYSICAL SERVER IN CLOUD COMPUTING SYSTEM, APPARATUS, AND SYSTEM

摘要

In a method for providing access to a service provided by a physical server in a cloud computing system, a cloud platform allocates to the service a publishing IP address and a publishing port, and sends a NAT rule to an access network element associated with the virtual machine. Upon receiving a service access request from the virtual machine for accessing the service, the access network element modifies, according to the NAT rule, a destination address of the service access request into the IP address and the port of the physical server that provides the service, and routes the modified service access request to the physical server.
