Embodiments of the present disclosure relate to a method and an apparatus for compressing metadata in a file system. The method comprises, in response to receiving a first request for writing first data to a file, determining whether the first request is for an initial write to a storage area associated with a second indirect block in the first group of indirect blocks, the first group of indirect blocks at least including a first indirect block and the second indirect block. The method further comprises, in response to the initial write, allocating a first group of data blocks for writing the first data on a storage device. In addition, the method further comprises compressing the first group of indirect blocks by encoding a first group of storage addresses corresponding to the first group of data blocks into the first indirect block.

The present disclosure provides a method and apparatus for storing data. The method comprises: extracting metric information and metadata associated with the metric information from time series data, the metric information including a time value and a numerical value at the time value; and staling the metric information in an object storage device and the metadata in a database. As compared with the prior art, the present disclosure provides a flexible storage design to guarantee extensibility of storage capacity and meanwhile support fast data retrieving.

Method and apparatus for storing data

A scheduler module receives a first allocation request for a given amount of a resource in a cloud computing platform that an application program currently needs. The scheduler module allocates the given amount of the resource to the application program for a first time slot. The given amount of allocated resource is received back at the scheduler module upon expiration of the first time slot for subsequent allocation. The scheduler module receives a second allocation request for a given amount of a resource that an application program currently needs. The scheduler module allocates the given amount of the resource to the application program for a second time slot. The given amount of allocated resource is received back at the scheduler module upon expiration of the second time slot for subsequent allocation.

Spatial-temporal cloud resource scheduling

Embodiments of the present disclosure provide a method and apparatus for providing data storage service. The method comprises: receiving a storage service template from an user, the storage service template specifying a storage service policy for the user and a service instance to launch; and providing a storage service according to the storage service template; wherein the storage service policy defines a storage function to be performed for data of the user. With the method and apparatus according to embodiments of the present disclosure, a unified solution for overall orchestration of storage functions can be provided to enable the user to customize the required storage function flexibly.

Method and apparatus for data storage service

A time-series data cache is operatively coupled between a time-series analytics application program and a time-series data store, and configured to temporarily store portions of the time-series data. The time-series data store is configured to persistently store time-series data. The time-series data cache is further configured to be responsive to one or more data read requests received from the time-series analytics application program.

Data caching for time-series analysis application

Embodiments of the present disclosure relate to a method and a device of resource orchestration resources using an object-oriented language, and a program. Specifically the present disclosure discloses a method of resource orchestration using an object-oriented language comprising: creating a correspondence relationship from concepts in the object-oriented language to a requirement of resource orchestration; creating a workflow for implementing the resource orchestration and based upon the correspondence relationship; and implementing the resource orchestration based upon the correspondence relationship and the workflow. The present disclosure also discloses a device of resource orchestration using an object-oriented language, and a computer program product for performing steps of a method of resource orchestration using an object-oriented language.

Method and device of resource orchestration using an object-oriented language

A method for managing container images in a container hosting environment, comprising a set of machine nodes for hosting container images, comprises the following steps. At a machine node of the set of machine nodes, at least one image layer of a container image comprising multiple image layers is identified for compaction. The identified image layer is compacted by merging data of the identified layer with data of another image layer of the container image. The data of the compacted image layer is transmitted to a backup store remote from the machine node for storage. The set of machine nodes and the backup store are implemented via processing devices operatively coupled via a communication network to form the container hosting environment. The compacted image layer may then be recovered from the backup store.

Container image layer compaction

A method for processing a data request in a software defined storage system, wherein the software defined storage system comprises one or more nodes configured as a set of client modules operatively coupled to a set of server modules, comprises the following steps. A data request with a data set is received at one of the set of client modules. One or more data services (e.g., deduplication and/or data compression) are performed on the data set, wherein the performance of the one or more data services on the data set is dynamically shared between one or more of the set of client modules and one or more of the set of server modules.

Data services for software defined storage system

A method of controlling one or more data services in a computing environment includes the following steps. A request to one of read data from and write data to one or more storage devices in a computing environment is obtained from an application executing on a host device in the computing environment. One or more application-aware parameters associated with the data of the request are obtained. Operation of the one or more data services is controlled based on the one or more application-aware parameters.

Application-aware control for data services

A container image registry is maintained at each host device in a set of host devices in a container hosting environment. A container image is composed of one or more container image layers such that each container image registry of each host device is configured to be able to store one or more different layers of one or more different container images. The method tracks which container image registry at which host device contains which container image layers. At each host device, one or more container images are obtained for launching one or more application programs. For a given host device, the one or more container images are obtained from one or more of: (i) one or more container image layers stored in its container image registry; and (ii) one or more container image layers stored in the container image registry of another host device.
