Abstract: Techniques for clustering a plurality of virtual space servers based on communication platform data are discussed herein. In some examples, a user may post a message to a virtual space of a communication platform. The communication platform may transmit the message to virtual space servers configured to manage the virtual space within which the message originated. In such examples, the communication platform may identify clusters of virtual space servers and determine within which cluster the corresponding virtual space server is located. Virtual space servers may be clustered based on attribute data associated with communication platform data. In some examples, the communication platform may send the message to the virtual space server which may send the message to subscribing gateway servers. Further, the gateways servers may send the message to the recipient client devices. The recipient client devices may display the message via a user interface of the communication platform.
