Abstract: A method, an apparatus, and computer instructions are provided for a design pattern for automating service provisioning. Embodiments of the invention provide a catalog item management system that comprises a set of service and catalog item management functions that manage lifecycles of services and catalog items. Embodiments of the invention also provide an order fulfillment system that comprises a set of order, subscription, and service instance functions for managing orders, subscriptions, and service instances in order to provision and deprovision an application. In addition, embodiments of the invention provide a calendar reservation and scheduling system that presents a list of resource availabilities using an algorithm. Furthermore, embodiments of the invention provide a provisioning process that includes a process order method that initiates reservation of resources, provisioning, deprovisioning, and modification of services based on an order type.

Abstract: A method, an apparatus, and computer instructions are provided for determining data center resource availability using multiple time domain segments. A reservation class is provided that includes a start time, duration and the number of units required. A scheduled resource class is provided with an availability and an available method. The availability method creates a set of segments for a list of reservations and iterates each segment to determine whether there are enough resources for the required units. The availability method then combines all adjacent reservations and removes reservations that are too short for the duration. The available method provides a way for user to determine if resources are available at and for a given time. A composite resource class is also provided for more than one scheduled resource with an availability and available method.

Abstract: There is provided in an embodiment of the present invention a method wherein a processor may receive a test configuration deployment plan (TCDP) template. A user may select the test configuration deployment plan template and provide time schedule, and specific software application names and version numbers as settings for variables within the test configuration deployment plan template, in effect making a subscription request, wherein the processor receives or otherwise prompts to receive such information. Provided such resources are available at the requested time, the processor may wait until that time and provision the test configuration deployment plan to a data center resource. Test cases are run and results are collected until time or test cases are exhausted. The processor may then release resources that had been allocated to the subscription, which may include a step of undeploying or unprovisioning.

Abstract: There is provided in an embodiment of the present invention a method, an apparatus and a program product for managing the capacity utilization estimate of a data center logical model. A data center logical model which may be based on actual physical resources of a data center physical resource is registered. An injected test load is then received which serves as the basis for a simulation, which may include fulfillment of service orders and provisioning of service orders. Usage data is next collected at the conclusion of executing injected test load. If the usage data contains a capacity utilization that does not meet a capacity threshold specified by the system owner, a further iteration of simulation may occur, in conjunction with modifying the load parameters, or changing the resources available to the data center logical model.

Abstract: 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.

Abstract: A method, apparatus, and computer instructions are provided for deploying and instantiating multiple instances of applications in automated data centers using an application deployment template. A first mechanism is provided to deploy multiple instances of applications using an application deployment plan template. The first mechanism uses deployment parameter sets to generate corresponding deployment plans based on the deployment template. A second mechanism is provided to instantiate multiple instances of applications using deployment plan templates. A service catalog that is exposed to consumers for selection of catalog items is built on top of the second mechanism. During the cataloging and order fulfillment process, the second mechanism instantiates multiple instances of applications using the generated deployment plans and an application model to deploy multiple application instances. An existing order may also be modified or terminated responsive to a user request or service term expiration.

Abstract: There is provided a data processing system-implemented method, system and an article of manufacture for providing a serviceability framework for autonomic resource management in a computer data centre. The data centre is monitored based on a logical representation (model) in the serviceability framework representative of the actual physical devices. The data centre logical model is constantly synchronized with the physical devices of the actual data centre where inconsistencies occur, and fast reporting is required before more problems occur. Monitoring agents associated with all the data centre devices are implemented to quickly identify and deal with problems before human intervention is required. A data centre health monitor is capable of detecting the malfunctions of typical devices and sub-systems in the data centre. For problems or failures that require drastic steps, the subsystem may be isolated and then interrogated separately from the rest of the data centre.
