Message broadcasting method, device, equipment, storage medium and computer program product

The embodiment of the invention discloses a message broadcasting method, device and equipment, a storage medium and a computer program product, which can be applied to scenes such as cloud technology, artificial intelligence, intelligent traffic and auxiliary driving. The target occupation capacity of the target group to the server side can be estimated; if the target occupancy capacity is greater than the current actual occupancy capacity, expanding the server occupied by the target group to obtain an expanded server cluster; establishing on-line marking information corresponding to each on-line group user, and storing the on-line marking information corresponding to the plurality of on-line group users to a plurality of sub-servers in the server cluster; and when a group message sent by the online group user is received, sending the group message to the plurality of sub-servers after storage updating, so that each sub-server broadcasts the group message to the online group user storing the online marking in
