Communication method, system and apparatus

A communication method implemented by a first server of a communications system, wherein the communications system comprises a first data center that comprises the first server, a first storage server, a first message proxy, and a first routing proxy, and wherein the communication method comprises:

• receiving a first message from a first application;
• determining that the first message is to be processed by a second data center;
• adding, in response to determining that the first message is to be processed by the second data center, routing information to the first message to generate a second message;
• storing the second message in a public area of the first storage server, wherein the first storage server comprises a private area and the public area, wherein the private area is configured to store messages processed by the first data center, and wherein the public area is configured to store messages processed by data centers other than the first data center;
• and
• sending the second message to the second data center based on the routing information.

A computer program product comprising computer-executable instructions for storage on a non-transitory computer-readable storage medium that, when executed by a processor, cause a first server of a first data center to:

• receive a first message from a first application that runs on a service server;
• determine that the first message is to be processed by a second data center;
• add, in response to determining that the first message is to be processed by the second data center, routing information to the first message to generate a second message;
• store the second message in a public area of a first storage server, wherein the first storage server comprises a private area and the public area, wherein the private area is configured to store messages processed by the first data center, and wherein the public area is configured to store messages processed by data centers other than the first data center;
• obtain the second message from the public area;
• and
• send the second message to the second data center based on the routing information.
