Systems and methods are taught for providing customers of a cloud computing service to control when updates affect the services provided to the customers. Because multiple customers share the cloud's infrastructure, each customer may have conflicting preferences for when an update and associated downtime occurs. Preventing and resolving conflicts between the preferences of multiple customers while providing them with input for scheduling a planned update may reduce the inconvenience posed by updates. Additionally, the schedule for the update may be transmitted to customers so that they can prepare for the downtime of services associated with the update.

Tenant-controlled cloud updates

Tenant-controlled cloud apparatus

The techniques and arrangements described herein provide for updating services, host operating systems and other applications while satisfying update domain constraints. In some examples, one or more controller modules may maintain a data structure including a plurality of server update domains, each server update domain including a set of machines of a plurality of machines of a distributed computing system which may be concurrently updated. The one or more controller modules may allocate the plurality of instances to the plurality of machines such that a number of server update domains is minimized.

Service allocation in a distributed computing platform

Data-parallel computation programs may be improved by, for example, determining the functional properties user defined functions (UDFs), eliminating unnecessary data-shuffling stages, and/or changing data-partition properties to cause desired data properties to appear after one or more user defined functions are applied.
