Access of data center resources is provided by the present invention using stateless and stateful Web services. For stateless Web services, the present invention provides an invoker API that allows a client to invoke a specific resource and perform an operation on the resource. For stateful Web services, the present invention provides a Web Service Definition file that defines attributes and operations for data center resources. The client may access an instance of a Web service resource once an endpoint reference is obtained from the server. Since the resource instance is persistent, the client may invoke data center operations and manipulate the resource attributes accordingly.

managing data center using web services

Provisioning grid resources for a set of grid services is provided. The service performance for the set of grid services is monitored. The set of grid services has a set of service level agreements. In response to monitoring service performance, a determination is made as to whether current allocations of grid resources is sufficient to maintain performance levels for the set of grid services to meet the set of service level objectives. In response to the current allocations being insufficient to maintain the performance levels, the current allocations of the grid resources are dynamically reallocated or provisioned for the set of grid services to maintain service levels for the set of grid services.

Provisioning grid services to maintain service level agreements

Computer implemented method, system and computer usable program code for configuring a computing system. A determination is made whether there are any errors in the model, and responsive to determining that there is at least one error in the model, a determination is made whether there is at least one resolution for correcting the at least one error. Responsive to determining that there is at least one resolution for correcting the at least one error, at least one resolution among the at least one resolution for correcting the at least one error is selected to form at least one selected resolution to correct the at least one error. The at least one selected resolution is applied to the model to form a transformed model, and the transformed model is output to a user.

Method and system for modeling, validating and automatically resolving goals and dependencies between elements within a topology

Computer implemented method, system and computer usable program code for configuring a computing system. A system for configuring a computing system includes a mechanism for creating a model of a computing system, a validator for determining whether there are any errors in the model, and a resolver, responsive to determining that there is at least one error in the model, for determining whether there is at least one resolution for correcting the at least one error. A selector, responsive to determining that there is at least one resolution for correcting the at least one error, selects at least one resolution among the at least one resolution for correcting the at least one error to form at least one selected resolution to correct the at least one error, and applies the at least one selected resolution to the model to form a transformed model. An output outputs the transformed model to a user.

The present invention provides dynamic configuration and allocation of resources in a data center. These resources are monitored for availability and performance information according to their assigned execution (or application) environments. The measured performance information for each environment is used to predict levels of demand for an application in the environment. From the predicted levels of demand resource requirements can be determined to provide a predetermined level of performance under the demand changes. The resources can then be reconfigured or reallocated to different environment so that the requirements of each environment can be met.

Method and system for managing resources in a data center

There is provided a method, a data processing system and a computer program product for maintaining service reliability in a data center. A probability of breach of a resource in the data center is determined. A breach of a resource may be the failure of the resource, the unavailability of a resource, the underperformance of a resource, or other problems with the resource. If the probability of breach exceeds a predetermined value, then additional resources are made available to the data center in order to prevent a breach of the resource from affecting the performance of the data center.

Maintaining service reliability in a data center using a service level objective provisioning mechanism

A method, apparatus, and computer instructions for provisioning grid resources for a set of grid services. The service performance for the set of grid services is monitored. The set of grid services has a set of service level agreements. In response to monitoring service performance, a determination is made as to whether current allocations of grid resources is sufficient to maintain performance levels for the set of grid services to meet the set of service level objectives. In response to the current allocations being insufficient to maintain the performance levels, the current allocations of the grid resources are dynamically reallocated or provisioned for the set of grid services to maintain service levels for the set of grid services.
