Abstract: A method for controlling transactional processing system having transactions that include multiple tasks, a throughput limit a transaction processing time limit includes allocating a plurality of threads to be used by multiple tasks to achieve a throughput approximating the throughput limit. The method assigns the multiple tasks to the plurality of threads and assigns respectively different processing delays to the plurality of threads. The processing delays span an interval less than the transaction processing time limit. The method processes the multiple tasks within the transaction processing time limit by executing the plurality of threads at times determined by the respective processing delays.

Abstract: Disclosed are embodiments for information barriers that are conditional on the type of information being communicated. Information barrier polices provided by the disclosed embodiments selectively allow communication between accounts or groups based on characteristics of the content of the communication. For example, communication between a marketing department and an engineering department may be conditional on the communication not including any sensitive information. The determination of whether the communication includes sensitive information is further designed to provide good performance even in environments that maintain substantial portions of data in an offsite or cloud environment, where latencies associated with searching large datastores can be prohibitive.

Abstract: Aspects of the subject matter described herein relate to simulating storage devices. In aspects, a test automation engine instructs a simulator to simulate a storage device having certain characteristics such as a storage area network. The test automation engine then tests an application against the simulated storage device. Tests may include storage management requests and storage access requests. A provider may translate a request to one or more operations suitable to perform the request on the underlying simulated device. Shadow copies and the results of other storage management-related operations may be shared across computers via aspects of a simulation framework described herein.
