CLOUD SYSTEM, MESSAGE PROCESSING METHOD AND APPARATUS, AND NETWORK CARD

Disclosed in the present application are a cloud system, a message processing method and apparatus, and a network card. The cloud system comprises: a computing node, which is used for inserting a network card and running a first virtual instance; the network card, which is used for receiving a first message in a first data stream; a network controller, which is used for transmitting, to a first central node, tenant network information of at least one virtual instance in one or more VPCs, wherein the network card is further used for sending the first message to the first central node when it is determined that a processing rule for the first message is not recorded locally; and the first central node, which is used for generating a first message processing rule corresponding to the first data stream, wherein the network card is further used for receiving and locally recording the first message processing rule sent by the first central node, so as to process and/or forward a message after the first message in t
