Embodiments of the present invention provide a method, system and computer program product for network aware provisioning in a mobility supporting cloud computing environment. In an embodiment of the invention, a method for network aware provisioning in a mobility supporting cloud computing environment is provided. In the method, a request is received from a mobile computing device for access to a service in a cloud computing environment and both an expected path of travel for the mobile computing device and also a network access speed along the expected path of travel is determined. Thereafter, a particular instance of the service executing in a host in the cloud computing environment able to accommodate a degree of interaction between the mobile computing device resulting from the network access speed determined for the expected path of travel is selected. Finally, the particular instance of the service is provisioned for access by the mobile computing device.

Workload requests are routed in response to server greenness conditions. A workload request is received for a remotely invocable computing service executing separately in different remotely and geographically dispersed host computing servers. Greenness conditions pertaining to production or conservation of energy based upon external factors for each of the different remotely and geographically dispersed host computing servers are determined. The workload request is routed to one of the different remotely and geographically dispersed host computing servers based upon the determined greenness conditions.

A method for the autonomic management of autonomic systems can include monitoring a managed system and recommending a course of action to be performed in the managed system. It can be determined whether the recommended course of action has been performed by an administrator. Responsive to the determination, it further can be determined whether an outcome from the course of action comports with a predicted outcome. If so, a point count can be changed responsive to a further determination that the outcome from the course of action comports with the predicted outcome. Conversely, the point count can be oppositely changed responsive to a further determination that the outcome from the course of action does not comports with the predicted outcome. In any case, when the point count crosses a threshold value, the management of the managed system can be transitioned to an adaptive component.

Techniques are disclosed for storing content in distributed computing environments to reduce storage overhead and improve efficiency and/or speed of accessing and delivering the stored content. A content management system (or other authoring system, such as a text editor) supplies hints about dependencies among objects or files, such as which objects are embedded into a web page and which objects are referenced by the web page. These hints are then used when deploying the corresponding files on a storage system, such that the files which are likely to be retrieved together are (preferably) stored together. Optionally, run-time observations by a web server may be used as input to this process to determine how best to store content during a subsequent redeployment.

Storage-Assisted QoS. To provide storage-assisted QoS, a discriminatory storage system able to enforce a service discrimination policy within the storage system can include re-writable media; a storage system controller; a cache; and, a QoS enforcement processor configured to selectively evict entries in the cache according QoS terms propagated into the storage system through the storage system controller.

A computing device associated with a cloud computing environment identifies a first worker cloud computing device from a group of worker cloud computing devices with available resources sufficient to meet required resources for a highest-priority task associated with a computing job including a group of prioritized tasks. A determination is made as to whether an ownership conflict would result from an assignment of the highest-priority task to the first worker cloud computing device based upon ownership information associated with the computing job and ownership information associated with at least one other task assigned to the first worker cloud computing device. The highest-priority task is assigned to the first worker cloud computing device in response to determining that the ownership conflict would not result from the assignment of the highest-priority task to the first worker cloud computing device.
摘要:
A request for content is received at a content server via a first network connection from a client device. The content includes a set of portions represented within a root document. Based upon a download constraint of at least one portion of the content and a network characteristic of the first network connection, at least one portion of the content is deferred for download over a network connection other than the first network connection. The content is sent with each deferred portion of the content replaced with a content stub within the root document. Each content stub identifies the respective portion of the content as a deferred portion of the content and includes a content identifier of the respective deferred portion of the content.

Embodiments of the present invention provide a method, data processing system and computer program product for mobility aware cloud provisioning. In an embodiment of the invention, a method for mobility aware provisioning of access to a service instance executing in a host in a cloud computing can include receiving a request from a mobile computing device for access to a service in a cloud computing environment. Thereafter, an expected path of travel for the mobile computing device can be computed and a particular instance of the service executing in memory of a host in the cloud computing environment can be selected for its proximity to the expected path of travel. Finally, the particular instance of the service can be provisioned for access by the mobile computing device.
