System and methods may include receiving a request for assigning resources to a first application associated with a first entity, the first application having a plurality of levels of performance each corresponding to a different power consumption; and determining a particular level of performance of the first application to run on the resource under a first constraint that a sum of a power consumption of the first application running at the particular level of performance and power consumptions of one or more other resources running other applications associated with the first entity is less than or equal to a power budget associated with the first entity.

Unified power management

A lease-based heartbeat protocol method is provided. The method may include sending a heartbeat request to a server device in a lease period, and receiving a heartbeat request response from the server device; and determining a retry sending at adaptive interval in response to the heartbeat request response being abnormal, and sending a retry heartbeat request to the server device again after the retry sending interval is past, until the lease period expires or a corresponding heartbeat request response is normal. As such, two successive retry heartbeat requests can be sent at a relatively large time interval at an initial stage of heartbeat request retry. At a later stage of the heartbeat request retry, the time interval associated with the retry heartbeat requests is reduced, such that re-sent heartbeat requests can be sent at a higher speed.

Lease-based heartbeat protocol method and apparatus

A system, apparatus, and method for maintaining the consistency of global information is disclosed herein. In one embodiment, the method includes retrieving current version information associated with the global information from a global information server; retrieving global information from the global information server based on the current version information; updating a period of validity of the current version information based on a status of communication with the global information server; and suspending a network service for the global information when detecting that the period of validity of the current version information has expired.

System and method for acquiring, processing, and updating global information

A system, apparatus, and method for maintaining the consistency of global information is disclosed herein. The method includes storing historical version information associated with global information; retrieving current version information associated with the global information from a global information server; generating updated historical version information based on the current version information; transmitting an update confirmation notice to the global information server; and retrieving updated global information from the global information server based on the updated historical version information.

System and method for acquiring, processing and updating global information

The present disclosure is directed to a cross-regional data transmission method and device. Metadata information sent by a corresponding client device is acquired, and the metadata information is sent to a corresponding metadata transmission node device, wherein the metadata information includes data replication progress information of the corresponding client device; to-be-forwarded data information sent by the corresponding metadata transmission node device is acquired, and the to-be-forwarded data information is pushed to the corresponding client device, wherein the to-be-forwarded data information includes data replication progress information of another client device, so that the metadata information sent by the corresponding client device is effectively sent to the corresponding metadata transmission node device; and the acquired to-be-forwarded data information sent by the corresponding metadata transmission node device is pushed to the corresponding client device, to achieve synchronization of the metadata information.

Method of cross-regional data transmission and system thereof

Embodiments of the disclosure describe a system, method, and apparatus for acquiring global information. The method comprises receiving current version information from a global information server, the current version information associated with current global information and associated with a network service; retrieving the current global information associated with the current version information and associated with the network service from the global information server; and providing or suspending the network service associated with the current global information based on a presence of a stop-write identifier in the current global information.
