Systems and methods including one or more processing modules and one or more non-transitory storage modules storing computing instructions configured to run on the one or more processing modules and perform acts of: initiating a cluster of controller instances in a cloud environment for executing a multi-dimensional event engine; and configuring the cluster of controller instances in a topology that provides availability and redundancy for the multi-dimensional event engine. An active controller instance is configured to: detect a current level of network traffic; receive the messages from an order management system; select a transmission rate for sending the messages to the fulfillment centers based on the current level of the network traffic; transmit the messages to the one or more fulfillment centers in accordance with the transmission rate; and dynamically adjust the transmission rate in response to detecting changes in the network traffic.
