The present invention discloses a data stream distribution method and apparatus. In the method, a load balancer may access data in a data stream according to an instruction in a distribution rule that is sent by an application server according to an interface protocol or configured on the load balancer according to an interface protocol; determine, according to a keyword generated according to the accessed data, an application server that processes the data stream; and send the data stream to the determined application server. Therefore, the load balancer may access the data in the data stream according to an instruction in a common distribution rule, to distribute the data stream, thereby reducing complexity of data stream distribution performed by the load balancer.
