A system includes a goal state repository, a goal state repository instance and management tools. The goal state repository stores goals for a managed system. The goal state repository instance stores a subset of the goals applicable to a current state of the managed system. The goal state repository instance is created by comparing the current state of the managed system to the goals stored in the goal state repository. The management tools modify the managed system to be in compliance with the subset of goals stored in the goal state repository instance.

According to one embodiment of the present invention, a method comprises providing a machine-readable monitoring model that maintains configuration of a monitoring environment. An element of the monitoring environment reads the machine-readable monitoring model and adapts its operation to the configuration defined thereby.

Computer resources from a pool of resources are allocated for executing an application. An amount of unutilized resources in the pool of resources is determined. One or more sets of resources previously allocated to execute the application are selected, and the unutilized resources are distributed among the sets of resources.

A computer network system having an overlay network, which comprises of a plurality of nodes and an initiator node connected via a reference. The generalized references are links, which interconnect the nodes and form an overlay topology. The system uses position information in the overlay topology for message routing between participating applications in the overly network. The automatic generation of path-based service identifiers and service locations is another aspect of the system.

One embodiment is a method that receives a description of services desired by a service requestor and then crawls web sites to extract information on services offered by service providers. The extracted information is used to transform the description of services desired by the service requestor into an improved description of services.
摘要:
One embodiment is a method that receives a list of service providers offering services at web sites and extracts content from the web sites to identify the services offered by the service providers. The method then populates service registries with the content.

A method of determining a placement of services of a distributed application onto nodes of a distributed resource infrastructure comprises first, second, and third steps. The first step forms communication constraints between node pairs. The communication constraints ensure that a sum of transport demands between a particular node pair does not exceed a transport capacity between the particular node pair. Each term of the sum comprises a product of a first placement variable, a second placement variable, and the transport demand between the services associated with the first and second placement variables. The second step forms an objective. The communication constraints and the objective comprise an integer program. The third step employs a local search solution to solve the integer program, which determines the placement of the services onto the nodes.

According to one embodiment, a method comprises storing metric definitions for at least one monitored component in a machine-readable format to a data storage device. The method further comprises enabling access by at least one monitoring tool to the metric definitions via a metric introspection interface. The method further comprises the at least one monitoring tool autonomously comprehending the metric definitions for use in processing monitoring data collected for the at least one monitored component.
摘要:
A method for format-independent advertising capabilities of data centers. In various embodiments, respective capability data sets are registered to a computing arrangement for one or more data centers. Each capability data set indicates resources available at a data center. Respective format descriptions are associated with the capability data sets, wherein each format description defines a syntax in which capabilities are described in a capability data set. Respective terms descriptions of terms are associated with the capability data sets, wherein each terms description defines the semantic meaning of a terms used in a capability data set. The computing arrangement receives queries that indicate capability requirements of a data center. In response to a query, the capability data sets that match the query are provided to the requesting entity.
摘要:
In an embodiment of a method of determining a value changes for a placement variable as part of a local search solution to an integer programming problem that models placement of services of a distributed application onto nodes of a distributed resource infrastructure, an unsatisfied communication constraint is selected. The unsatisfied communication constraint includes a sum of terms where at least some of the terms comprise products of placement variables. Stores are created for allowable changes of value for the variables in the unsatisfied communication constraint. The unsatisfied communication constraint is parsed through by term. For each variable in a term, the stores are updated with a change in the term for each of the allowable changes of the value while maintaining other variables constant. A variable to receive the value change, and possibly a value for the variable, are chosen based upon the store which meets at least one improvement criterion.
