Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating recipes having platform-independent, resource-agnostic commands for performing work in a cloud computing platform. One of the systems includes a plurality of executors, each executor being operable to receive a recipe comprising one or more platform independent, resource agnostic commands, each command corresponding to a requested service to be performed by an execution engine on an underlying computing platform, translate each platform independent, resource agnostic command of the recipe into one or more platform independent, resource specific requests that satisfy the requested service on the underlying computing platform and make each of the one or more platform independent, resource specific requests to one of the one or more execution engines using a platform independent execution engine application programming interface (API).

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for allocating tasks to computing nodes using multiple resource allocators. One of the methods includes providing, by each resource allocator of a plurality of resource allocators, a first request to compute a first score to each computing node of a plurality of computing nodes, the first score representing a measure of availability for the computing node to take a particular task. A first score is received from each of the plurality of computing nodes and the nodes are ranked according to the first scores. A second request is provided to a highest-ranked computing node to compute a second score. If the difference between the first score and the second score satisfies a threshold, assigning the task to the highest-ranked computing node if and only if the difference between the first score and the second score satisfies the threshold.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating recipes having platform-independent, resource-agnostic commands for performing work in a cloud computing platform. One of the systems includes a plurality of execution engines, each execution engine being installed on a particular instance of an underlying computing platform, wherein each execution engine is operable to receive, through an execution engine API by a first execution engine of the plurality of execution engines installed on a first instance of a particular underlying computing platform, a plurality of platform-independent, resource-specific requests from an executor to operate on a resources in an underlying computing platform and in response, perform one or more platform-independent, resource instance-specific operations to operate on a first resource on the first instance of the particular underlying computing platform.
