20160132360 | Stream Schema Resolution and Stream Tuple Processing in a Distributed Stream-Processing System - A task worker running on a worker server receives a process specification over a network. The process specification specifies a task to be executed by the task worker. The executed task includes generating an output data object for an output data stream based in part on an input data object from an input data stream. The process specification is accessed to specify the required fields to be read from for executing the task and to specify the generated the fields in the input data object that will be written to during or subsequent to the executing of the task. The task worker executes the task and generates the output data object. The output data object is then transmitted to the output stream based on the stream configuration. | 05-12-2016 |

20140195672 | AUTOMATED FAILURE HANDLING THROUGH ISOLATION - Embodiments are directed to isolating a cloud computing node using network- or some other type of isolation. In one scenario, a computer system determines that a cloud computing node is no longer responding to monitoring requests. The computer system isolates the determined cloud computing node to ensure that software programs running on the determined cloud computing node are no longer effectual (either the programs no longer produce outputs, or those outputs are not allowed to be transmitted). The computer system also notifies various entities that the determined cloud computing node has been isolated. The node may be isolated by powering the node down, by preventing the node from transmitting and/or receiving data, and by manually isolating the node. In some cases, isolating the node by preventing the node from transmitting and/or receiving data includes deactivating network switch ports used by the determined cloud computing node for data communication. | 07-10-2014 |
20140195853 | CLOUD MANAGEMENT USING A COMPONENT HEALTH MODEL - Embodiments are directed to establishing a model for testing cloud components and to preventing cascading failures in cloud components. In one scenario, a computer system models identified cloud components (including cloud hardware components and/or cloud software components) as health entities. Each health entity is configured to provide state information about the cloud component. The computer system establishes declarative safety conditions which declaratively describe cloud computing conditions that are to be maintained at the identified cloud components. The computer system then tests against the declarative safety conditions to determine which cloud components are or are becoming problematic. Upon determining that an error has occurred, the computer system notifies users of the error and the component at which the error occurred. Guarded interfaces are established to ensure that actions taken to fix the error do not cause further failures. | 07-10-2014 |
20140195861 | IMPLEMENTING RATE CONTROLS TO LIMIT TIMEOUT-BASED FAULTS - Embodiments are directed to implementing rate controls to limit faults detected by timeout and to learning and adjusting an optimal timeout value. In one scenario, a computer system identifies cloud components that have the potential to fail within a time frame that is specified by a timeout value. The computer system establishes a number of components that are allowed to fail during the time frame specified by the timeout value and further determines that the number of component failures within the time frame specified by the timeout value has exceeded the established number of components that are allowed to fail. In response, the computer system increases the timeout value by a specified amount of time to ensure that fewer than or equal to the established number of components fail within the time frame specified by the timeout value. | 07-10-2014 |
