Techniques for scaling an event broker via two-way traffic learning

A distributed computing system, comprising:

• one or more processors;
• and
• one or more memories storing computer-executable instructions that, when executed by the one or more processors, cause the distributed computing system to:
• obtain, by a message broker service executing in the distributed computing system, quality of service metrics, the message broker service comprising a plurality of message broker instances;
• determine, by the message broker service and based at least in part on the quality of service metrics, a number of message broker instances to send messages to subscribing clients;
• determine, by the message broker service, whether the number of message broker instances exceeds the plurality of message broker instances;
• and
• based at least in part on a determination that the number of message broker instances exceeds the plurality of message broker instances, execute, by the message broker service, the number of message broker instances.

A non-transitory computer-readable medium comprising executable instructions that, when executed by one or more processors of a distributed computing system, cause the distributed computing system to:

• obtain, by a message broker service executing in the distributed computing system, quality of service metrics, the message broker service comprising a plurality of message broker instances;
• determine, by the message broker service and based at least in part on the quality of service metrics, a number of message broker instances to send messages to subscribing clients;
• determine, by the message broker service, whether the number of message broker instances exceeds the plurality of message broker instances;
• and
• based at least in part on a determination that the number of message broker instances exceeds the plurality of message broker instances, execute, by the message broker service, the number of message broker instances.
