Abstract: This present disclosure provides for a work distribution service, which is a multi-region, reliable service for dynamically sharding key ranges. The work distribution service offers exclusive ownership with leases, load balancing and routing information for owner discovery. Using the work distribution service, services can easily scale horizontally by sharding their workloads.

Abstract: The present disclosure describes a queued message service (QMS) that provides a multi-region, low-latency and reliable service for managing a large number of durable message queues for async targeted communication. This general-purpose, internal service QMS may be implemented in print queues as well as command queues for sensors. One example implementation of QMS is a print service. Such implementation introduces status indicators for printers internally, wherein such status indicators may identify whether a printer is blocked, offline, suspected of failure, properly functioning, etc.
