摘要:
On demand image streaming (ODS), in one aspect, may perform both copy-on-write and copy-on-read to gradually bring data on remote storage server to a host's local disk. Prefetching may be performed during the time the resources are otherwise idle to bring in data from the remote storage server to the host's local disk. A new image format and the corresponding block device driver for a hypervisor or the like may be also provided. ODS' image format may include a header and a bitmap that indicates whether the data sectors are on local disk or remote storage server, and an image content, for instance, stored in raw format.

A data model represents semantic information associated with objects stored in a file system. The data model includes a first object identifier, a second object identifier and a relation identifier. The first object identifier identifies a first object stored in the file system. The second object identifier identifies a second object stored in the file system, wherein the second object is related to the first object. The relation identifier identifies a relationship between the first object and the second object.
摘要:
There are provided a system and method for resource adaptive, real-time new event detection. The method includes capturing, from among documents in a document streaming environment, first-story documents that mention previously unmentioned events. The method further includes dynamically adjusting a thoroughness of the capturing step by controlling a number of keywords and documents considered according to a real-time system load.
摘要:
Services are provided via a multicast tree. A request to receive a service is received at a node. Stored information at the node is searched to identify a service path or a service node operable to provide the requested service.
摘要:
A method, an apparatus and an article of manufacture for remediating overload in an over-committed computing environment. The method includes measuring resource usage of each of multiple virtual machines on each of at least one hypervisor in a computing environment, upon detection of a resource overload on one of the at least one hypervisor, determining at least one operation that is to be taken for at least one of the multiple virtual machines on the hypervisor to remediate resource overload while increasing values of running virtual machines, and sending a command to the hypervisor to issue the at least one operation.
摘要:
Techniques for facilitating customer-initiated virtual machine (VM) migration and swapping. A method includes obtaining documentation of at least one performance parameter of two or more virtual machines running on two or more physical machines, obtaining a request for a virtual machine exchange from a user of a first virtual machine, wherein the request comprises a preference for at least one desired performance parameter in at least one additional virtual machine, matching the request from the user of the first virtual machine with at least one additional virtual machine that includes the at least one desired performance parameter without assistance from a cloud provider, and exchanging the first virtual machine with a virtual machine from the at least one additional virtual machine that includes the at least one desired performance parameter.
摘要:
A method, an apparatus and an article of manufacture for automated validation of compliance in a cloud server. The method includes remotely accessing a target cloud server to discover at least one configuration setting of the target cloud server, integrating the at least one configuration setting from the target cloud server with information from at least one back-end tool to produce compliance evidence, and automatically answering a set of at least one checklist question for activation compliance validation of the target cloud server based on the compliance evidence.
摘要:
A method to organize nodes into an overlay network and to disseminate multicast messages within this overlay both through an efficient tree embedded in the overlay and through gossips exchanged between overlay neighbors. Regardless of the size of the system, this invention incurs a constant low overhead on each node.
摘要:
A decentralized process to ensure the dynamic placement of applications on servers under two types of simultaneous resource requirements, those that are dependent on the loads placed on the applications and those that are independent. The demand (load) for applications changes over time and the goal is to satisfy all the demand while changing the solution (assignment of applications to servers) as little as possible.
摘要:
A multicast tree is provided in an application multicast network. A child node in the multicast tree detects a degradation of quality of service associated with a service being received at the child node. The child node determines whether the degradation of quality of service is resulting from a child-parent link or an upstream link in the multicast tree.
