20080215749 | PROVIDING DIFFERENT RATES TO DIFFERENT USERS OF A DOWNLOAD SERVICE - A system, computer program and method for transmitting requested data from a data source in response to data transmission requests from at least one electronic device according to differential rates of throughput. Data transmission requests are classified into one of a plurality of throughput classes, with each throughput class having an assigned rate of throughput. A proportion of data transmission requests to be processed from each throughput class is selected such that each data transmission request has a rate of throughput approximating the assigned rate of throughput of its class. The requested data is then sent from the data source to the electronic device. | 09-04-2008 |
20080216088 | Coordinating service performance and application placement management - Apparatus, systems and methods for service and/or business for coordinating tasks of performance management and application placement management in a dynamic fashion. An example process is dynamic in the face of fluctuations in the request load to the distributed computer system and the periodic adjustments to the placement of applications onto servers in said distributed computer system. There are two opposite functional flows in said process: a demand estimation function and a capacity adjustment function. The coordination system involves two subsystems: a demand estimator and a capacity adjuster, along with appropriate interfaces to of the performance manager and the application placement manager. This results in application placement process reacting quicker to demand fluctuations, performance guarantees are better met by rearranging the resources to be allocated to the various classes of service, and the management system works in an unsupervised mode, thus reducing manual administration costs and human errors. | 09-04-2008 |
20080235705 | Methods and Apparatus for Global Systems Management - Techniques for globally managing systems are provided. One or more measurable effects of at least one hypothetical action to achieve a management goal are determined at a first system manager. The one or more measurable effects are sent from the first system manager to a second system manager. At the second system manager, one or more procedural actions to achieve the management goal are determined in response to the one or more received measurable effects. The one or more procedural actions are executed to achieve the management goal. | 09-25-2008 |
20080244595 | METHOD AND SYSTEM FOR CONSTRUCTING VIRTUAL RESOURCES - System for managing a life cycle of a virtual resource. One or more virtual resources are defined. The one or more defined virtual resources are created. The created virtual resources are instantiated. Then, a topology of a virtual resource is constructed using a plurality of virtual resources that are in at least one of a defined, a created, or an instantiated state. | 10-02-2008 |
20080256534 | METHOD FOR IMPROVED IMAGE-CUSTOMIZATION BY USE OF EMBEDDED METADATA - The present invention relates to a method for the customization of virtual machine images. The method comprises identifying and retrieving a virtual machine image template. A customized virtual machine image is created from the virtual machine image template. The customized virtual machine image template being created by identifying at least one file-system or memory image that is associated with the virtual machine image template, identifying within the at least one file-system or memory image at least one data set, wherein the at least one data set comprises metadata. The metadata contains information detailing the required execution context customization aspects for at least one specified image subset of the virtual machine. Execution context-specific information that is required to customize the image subset of the virtual machine is retrieved. Further, the image subset of the virtual machine is modified in accordance with the retrieved execution context-specific information. | 10-16-2008 |
20080301696 | Controlling workload of a computer system through only external monitoring - Provides control of the workload, flow control, and concurrency control of a computer system through the use of only external performance monitors. Data collected by external performance monitors are used to build a simple, black box model of the computer system, comprising two resources: a virtual bottleneck resource and a delay resource representing all non-bottleneck resources combined. The service times of the two resource types are two parameters of the black box model. The two parameters are evaluated based on historical data collected by the external performance monitors. The workload capacity that avoids saturation of the bottleneck resource is then determined and used as a control variable by a flow controller to limit the workload on the computer system. The workload may include a mix of traffic classes. In such a case, data is collected, parameters are evaluated and control variables are determined for each of the traffic classes. | 12-04-2008 |
20090077090 | METHOD AND APPARATUS FOR SPECIFYING AN ORDER FOR CHANGING AN OPERATIONAL STATE OF SOFTWARE APPLICATION COMPONENTS - A computer implemented method, apparatus, and computer usable program product for managing a distributed software application. The process identifies metadata describing a set of dependencies of a set of software components in the distributed software application from data associated with the set of software components. The process then identifies a sequence for changing an operational state of the set of software components of the distributed software application from the metadata to form an identified sequence. Thereafter, the process changes the operational state of the set of software components using the identified sequence. | 03-19-2009 |
20090106748 | METHOD AND SYSTEM FOR UPGRADING VIRTUAL RESOURCES - A system for upgrading a multi-tiered application. In response to receiving a request to upgrade a multi-tiered application, wherein components of the multi-tiered application are deployed across a plurality of virtual machines, an appropriate integrated patch is selected for the upgrade. The selected integrated patch includes an integrated set of patches for the components of the multi-tiered application, state update data, and order constraints. The components of the multi-tiered application specified in the selected integrated patch are upgraded by using the integrated set of patches and order constraints. In addition, the state of the components of the multi-tiered application are updated by using the state update data. Then, the updated state of the multi-tiered application is saved to storage. | 04-23-2009 |
20090157855 | DECENTRALIZED APPLICATION PLACEMENT FOR WEB APPLICATION MIDDLEWARE - A decentralized process to ensure the dynamic placement of applications on servers under two types of simultaneous resource requirements, those that are dependent on the loads placed on the applications and those that are independent. The demand (load) for applications changes over time and the goal is to satisfy all the demand while changing the solution (assignment of applications to servers) as little as possible. | 06-18-2009 |
20100223379 | COORDINATING SERVICE PERFORMANCE AND APPLICATION PLACEMENT MANAGEMENT - Coordinating tasks of performance management and application placement management in a dynamic fashion by: estimating capacity needs for various service classes of service requests; computing desired capacities of at least one application for said service requests; deciding whether the desired capacities are satisfied by a current application placement; making no change to current application placement if the desired capacities are satisfied; determining a new application placement based on the desired capacities and a projected load if the desired capacities are not satisfied; computing corresponding capacity constraints for all pairs of service classes and servers; and computing an optimal allocation of capacities among the service classes so as to optimize a quality of service. | 09-02-2010 |
20150052321 | MINIMALLY DISRUPTIVE VIRTUAL MACHINE SNAPSHOTS - Aspects of the present invention provide a solution for creating a snapshot of a virtual server. In an embodiment, a first write storage is created in response to a snapshot request. For each write from the virtual server to primary storage that is the first write of that particular data block since the snapshot request, the data that resided in the data block previous to the write is copied from the primary storage to the first write storage. | 02-19-2015 |
