Abstract: Improved messaging systems are disclosed. Embodiments allow message producers to access or create producer reservations in a queue coordination data store corresponding to a campaign. The producer reservations reflect a workload and a campaign aspect. A message producer can apply a usage strategy in resource selection which may optimize selection of queueing resources considering existing work volume for those message queues or aspects of the campaign. Message consumers may select message queues from which to consume messages using data in the queue coordination data store. A message consumer may apply a usage strategy in resource selection which may optimize selection of queueing resources considering existing work volume for those message queues of aspects of the campaign.

Abstract: Systems and methods for dynamic online signaling are disclosed. Embodiments of these systems and methods may determine when a user is online or when a user is otherwise performing certain activities and dynamically signal an interested entity based on the user's activity.
