Techniques are described for facilitating performance of tasks supplied by task requesters, such as by a task exchange server interacting with mobile task performer users available to perform tasks at various geographical locations. Some or all of the tasks may each be associated with geographical locations and/or other device-related criteria related to the performance of the task, and one or more mobile task performer users may be identified as being appropriate to perform the task based on the location of, qualifications of, and/or characteristics of mobile device(s) of the user. Such identified task performer users may then be notified of such appropriate tasks in various ways, such as by sending one or more electronic messages with information about the tasks to one or more mobile devices of the users, and may in some situations use one or more of their mobile devices as part of the task performance.

Controlling performance of location-based tasks by mobile task performers

Various embodiments of a system and method for diminishing workload imbalance across multiple database systems are described. Embodiments may include a resource balancer configured to, for each of a multiple database systems hosting database resources assigned to different user entities, generate a system usage score for that database system based on database usage scores of respective database resources hosted by that database system. Each usage score of a given database resource may indicate a quantity of work performed by the respective database system to process one or more requests directed to that database resource. The resource balancer may also be configured to generate one or more instructions to move a database resource from a first database system having a first system usage score to a second database system having a smaller system usage score in order to diminish an imbalance of workload across the database systems.
