Abstract: A serverless system includes a message management apparatus. The message management apparatus may receive a first message, where the first message is used to indicate to schedule a first stateful function to operate a first state instance; store the first message in a first message queue corresponding to the first state instance, where the first message queue is further used to store a plurality of messages, and each of the plurality of messages is used to indicate one stateful function to operate the first state instance; and transfer a second message to a second stateful function corresponding to the second message, and run the second stateful function corresponding to the second message to operate the first state instance that is in an idle state, where the second message is a message located at a foremost end of the first message queue.

Abstract: A distributed computing system including a load balancing engine is disclosed. The load balancing engine includes: a load information management module for obtaining global load information of the system; a service information management module for obtaining global service information of the system; a policy computing module for performing load balancing computing for a first service type by using the global load information and the global service information, to generate a first load balancing policy corresponding to the first service type; and a policy release module for releasing the first load balancing policy to a client.
