Abstract: Various embodiments predict performance of a system including a plurality of server tiers. In one embodiment, a first set of performance information is collected for a base allocation of computing resources across multiple server tiers in the plurality of sever tiers for a set of workloads. A set of experimental allocations of the computing resources is generated on a tier-by-tier basis. Each of the set of experimental allocations varies the computing resources allocated by the base allocation for a single server tier of the multiple server tiers. A second set of performance information associated with the single server tier for each of the set of experimental allocations is collected for a plurality of workloads. At least one performance characteristic of at least one candidate allocation of computing resources across the multiple server tiers is predicted for a given workload based on the first and second sets of performance information.

Abstract: A system in a cloud services environment comprises one or more service offerings, one or more service instances and one or more service support utilities. Each of the one or more service offerings is described by at least one service descriptor. Each of the one or more service instances is obtained from at least one of the one or more service offerings. Each of the one or more service support utilities is customized by at least one service descriptor. A service comprises at least one component and a service descriptor comprises one or more models.

Abstract: A system and method for web application navigation control includes updating navigation data models used in navigation constraints with received data from an end-user or system. Without needing a centralized application-specific controller, from a collection of extensible navigation rules associated with each page of a plurality of pages, the extensible navigation rules are automatically selected which depend on changed data values and need re-evaluation. The navigation constraints associated only with the pages potentially changing their ready state to execute from among the plurality of pages in an entire application are evaluated to determine which pages are ready to run based on updated data from the navigation data models. A preferred page to be actually navigated to next is selected from among a set of all available and ready pages by execution of a set of second and separate navigation constraints using results of the navigation constraints of the evaluating step.

Abstract: Various embodiments manage service labels for association with service specifications in a service-oriented environment. In one embodiment at least one candidate service label is received from a user associated with a service domain of a distributed federated service-oriented environment. The candidate service label includes at least one of a service type and a set of terms characterizing a service. The candidate service label is sent to a community of users associated with one or more service domains in the distributed federated service-oriented environment. One of a vote for accepting the candidate service label and a vote for rejecting the candidate service label is received from each of a plurality of users in the community of users. The candidate service label is stored as an accepted service label in the service domain based on a number of votes for accepting the candidate service label being above a given threshold.

Abstract: A small baseline audio sample is sampled when a person initially calls in and the sample is held only for the duration of the call. For each subsequent transfer, a comparison is made to the baseline established from the initial call and at the end of the call the voice sample is discarded so no resources need to be maintained. Speaker verification and VOIP technologies are used to persist the customer's verification information as service representative hand-offs occur.

Abstract: A method for processing a graph structure includes providing a graph as a set of triples, each triple having a subject node, a predicate, and an object node, the predicate defining a relationship between a respective subject node and an object node. One of more triples in the set of triples are processed according to one or more attributes of each triple in the set of triples to permit accessing, querying, creating, and updating resource description framework (RDF) data structures in at least one of a script language and an object oriented language by providing a set of language extensions.

Abstract: A system and method for distributed computation includes providing a first service of a first computation node in a network of nodes, the first service having a first resource, the first resource including one of references to data and other resources. In a second service on a second computation node, the first resource is reference-able by associating the first resource in the second service for use in the second service. A distributed computation is performed across node boundaries using the references of the first resource to perform the computation in the first service and in the second service.

Abstract: A system and method for managing resources in a programming environment includes providing mutable entities including related data including triples, listening for changes in the related data, and triggering a first construct in accordance with the changes in the related data to update the mutable entities. Updates are propagated from the first construct to other constructs such that a cascade of updates occurs. The cascade of updates is executed concurrently such that the updates are propagated to completion and are executed all at once relative to other cascades of executing constructs.

Abstract: A system and method for reducing complexity by reuse of programming models includes defining a model controller view (MVC) unit as a programming model abstraction in a first program and permitting access by a second program to a model in the MVC unit. The first program and the second program communicate to employ the model in the second program. Access of the model by the second program is responded to in the first program to execute an action.
