Abstract: Disclosed herein is a computer implemented method of operating a computing environment to perform a live migration of a running process from a current computing node to an alternative computing node. The current computing node is configured for executing an application binary using a sandboxed runtime environment that comprises an application binary interface. The alternative computing node is configured for executing the application binary using the sandboxed runtime environment that comprises the application binary interface. The application binary interface has a node hardware independent instruction set. The method comprises: monitoring the running process on the current computing node to see if it meets a predetermined transfer criterion; adding the running process to a workload queue if the predetermined transfer criterion is detected; and migrating the running process from the current computing node to the alternative computing node.

Abstract: Embodiments of the present invention provide computer-implemented methods, computer program products and computer systems for enabling modifying a behavior of a consuming component. The method comprises requesting a smart client by a consuming component. The smart client is adapted to modify a control logic of the consuming component and to establish a network connection. Next, the consuming component executes the smart client and receives a modification for the smart client of the consuming component. Further, a computer-implemented method for enabling modifying a behavior of a consuming component by a serving component is disclosed. This method comprises, upon receiving a request for a smart client by the serving component, providing a smart client, transmitting the smart client, receiving service requests comprising procedure calls to be executed by the serving component, and, upon detecting a performance change by the serving component, sending a modification for the smart client.

Abstract: Aspects of the present invention disclose a method, computer program product, and system for query execution in a multi-tenant cloud service. The method includes one or more processors determining category classes for service queries. The method further includes sending for execution, a selected number of service queries from one of the determined category classes to a shadow query engine. Respective service queries of the categorically classified service queries comprise a different set of configuration parameter values for the shadow query engine. The method further includes recording metadata for the selected number of service queries of the one category class executed on said shadow query engine. The method further includes determining correlations between the recorded metadata.
