Cloud-edge topologies

摘要

The description relates to cloud-edge topologies. Some aspects relate to cloud-edge applications and resource usage in various cloud-edge topologies. Another aspect of the present cloud-edge topologies can relate to the specification of cloud-edge applications using a temporal language. A further aspect can involve an architecture that runs data stream management systems (DSMSs) engines on the cloud and cloud-edge computers to run query parts.

1. A computer-readable storage media having instructions stored thereon that when executed by a computing device cause the computing device to perform acts, comprising:
evaluating a real-time streaming query that utilizes data from multiple different edge computing devices, the multiple different edge computing devices configured to communicate with cloud-based resources and to communicate indirectly with one another via the cloud-based resources, but not to communicate directly with one another, and wherein individual edge computing devices include an instantiation of an application or application part that is conveyed in a declarative temporal language; and, comparing resource usage between a first scenario that involves uploading query data, associated with the real-time streaming query, from the multiple different edge computing devices to the cloud-based resources for processing and a second scenario that involves uploading the query data from all but one of the multiple different edge computing devices to the cloud-based resources and downloading the query data to a sub/-set of the multiple different edge computing devices for processing, wherein the sub-set includes the one edge computing device.
