Abstract: Disclosed are various embodiments for replicating and maintaining aggregated descriptive data for cloud services. In one embodiment, updates to descriptive data that describes a resource of a customer provided by a cloud service are received by an aggregated descriptive data service from a backend service. An aggregated descriptive data store is then updated by the aggregated descriptive data service based at least in part on the received updates.

Abstract: Various embodiments for testing and verifying cloud services using computational graphs. In one embodiment, a computational graph is generated that represents corresponding actions performed by a plurality of agents and data associated with the corresponding actions. The computational graph is generated based at least in part on data describing a plurality of calls to an application programming interface (API) or a static analysis of the API. A plurality of test cases are generated for the API by analyzing the computational graph.

Abstract: A method for fabricating a strained Si based layer, devices manufactured in this layer, and electronic systems comprising such layers and devices are disclosed. The method comprises the steps of growing epitaxially a SiGe layer on a substrate, and creating a varying Ge concentration in this SiGe layer. The Ge concentration in the SiGe layer includes a unique Ge overshoot zone, where the Ge concentration is abruptly and significantly increased. The Si based layer is epitaxially deposited onto the SiGe layer, whereby is becomes tensilely strained. It is also disclosed that the strained Si based layer, typically Si or SiGe, can be transferred to a different bulk substrate, or to an insulator.
