Description:
FIELD OF THE INVENTION 
       [0001]    This disclosure relates to the field of communication, and in particular to a cloud service consuming method, a cloud service message packet, a cloud service broker and a cloud system. 
       BACKGROUND OF THE INVENTION 
       [0002]    As a new method for sharing the infrastructure, cloud computing can connect huge system pools to provide various IT services. 
         [0003]    Cloud computing can be usually classified as broad cloud computing and narrow cloud computing. In the above, the broad cloud computing means the delivery and usage pattern of services, and it means getting the needed services through the network according to demand and in an easily extendable way. Such services can be services related to IT, software and internet, and also can be any other services. 
         [0004]    At present, as the capability and interface between cloud computing are incompatible, when a cloud service requester (consumer) needs to use the cloud service, the cloud service requester has to send a request to different cloud service providers in order to get the cloud service information of the cloud service providers. If the cloud service provider is unable to provide the cloud service requested by the consumer, the consumer still needs to send a request to other cloud service providers to get the cloud service information till a cloud service provider that can provide the cloud service requested by the consumer. For example, if the consumer needs to use the cloud service provided by Google, but the consumer does not know that such cloud service is available in Google, and then the consumer first requests Amazon for the cloud service. At this moment, as Amazon is unable to provide the cloud service for the consumer, so the consumer can only respectively send a request to other cloud service providers till send a request to Google. It is thus clear that such cloud service access way is inconvenient for the consumer to request and use the cloud service. Also, as the consumer needs to send requests to different cloud service providers for many times, the system resources are wasted, and the system efficiency is low.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0032]    This disclosure will be described in details hereinafter with reference to drawings and embodiments. It should be noted that embodiments in the application and features in the embodiments can be combined with each other if there is no conflict. 
         [0033]    With reference to  FIG. 1 , a usage scenario diagram of a cloud service broker according to the embodiment of this disclosure is illustrated. 
         [0034]    The cloud service broker (also called cloud service gateway) provides brokering services for various cloud service providers, and cloud provided by the cloud service providers can be private cloud, community cloud, public cloud or hybrid cloud. The cloud service broker can provide services including but not limited to arbitration service, proxy service, monitoring service, transition service, porting service, control service, deployment service, shielding service, permutation service, security service and synthesis service or the like between various cloud service providers (cloud computing service providers) such as private cloud, community cloud, public cloud or hybrid cloud and cloud service requesters (consumers) such as WEB service, application or user (enterprise user and individual consumer). The cloud service broker can abstract the incompatible capabilities and interfaces between different cloud computing services, and provide public, open and standard brokering services for consumers. It can solve the problem of incompatibility between different cloud platforms/cloud computing services, provide optimal one-stop services for consumers, and fully meet the demands of consumers. 
         [0035]    As shown in  FIG. 1 , the cloud service broker is located between the cloud service requesters and the cloud service providers. Cloud service requesters such as WEB service, application or user (enterprise user and individual consumer) can access the cloud computing services and/or resources provided by the cloud service providers such as private cloud, community cloud, public cloud or hybrid cloud through the cloud service broker. It can be that the cloud service broker itself is not a cloud computing platform, and the cloud service broker also can be implemented by the cloud computing technology. 
         [0036]    The cloud service broker gets information of various cloud computing services and/or resources provided by the cloud service providers through the cloud service publishing function, and stores the information. The cloud service broker selects and/or adapts the cloud computing services and/or resources provided by the proper cloud service providers for the cloud service requesters, so that the cloud service requesters do not have to access different cloud service providers for many times. Thus, on one hand, the cloud service broker provides convenience for the cloud service requesters to use the cloud services, and on the other hand, it also provides a uniform management and usage platform for cloud service information provided by the cloud service providers. 
         [0037]    Through the cloud service publishing function, the cloud service broker can subscribe to information of the cloud computing services and/or resources published and supported by the cloud service providers such as private cloud, community cloud, public cloud or hybrid cloud. The cloud service providers such as private cloud, community cloud, public cloud or hybrid cloud can publish a notification of information of the cloud computing services and/or resources supported by themselves to the cloud service broker. 
         [0038]    Through the cloud service consuming function, the cloud service broker can, according to the consuming request of the cloud service requesters, select and/or adapt information of the cloud computing services and/or resources published and supported by the cloud service providers such as private cloud, community cloud, public cloud or hybrid cloud. 
         [0039]    With reference to  FIG. 2 , a step flow chart of a cloud service consuming method according to embodiments of this disclosure is illustrated, comprising the following steps. 
         [0040]    S 202 : A cloud service broker receives a cloud service consumer request sent by a cloud service requester; and 
         [0041]    the cloud service consumer request comprises cloud service information requested by the cloud service requester, for example, the request for usage of cloud storage service or the like. 
         [0042]    S 204 : The cloud service broker returns a cloud service consumer response to the cloud service requester. 
         [0043]    In the above, the cloud service consumer response comprises cloud service information provided by the cloud service broker. That is, the cloud service broker has selected and/or adapted the information of the cloud computing services and/or resources provided by a proper cloud service provider for the cloud service requester. The cloud computing services and/or resources provided by the proper cloud service provider can be real cloud computing services and/or resources of the cloud service provider, and also can be virtual cloud computing services and/or resources, i.e., the cloud computing services and/or resources of the cloud service provider processed by the cloud service broker (such as the services described hereinafter: the proxy service, transition service, porting service, shielding service, permutation service and synthesis service). 
         [0044]    According to the cloud service consumer request, the cloud service requester accessing and/or controlling the cloud services provided by the cloud service provider through the cloud service broker can include at least one of the following operation ways: creating, reading, updating, deleting, executing, copying, moving, selecting, collecting or the like. Through the above operations, different demands of the cloud service requester on cloud services are effectively met. 
         [0045]    In the related technologies, when the cloud service requester needs cloud services, the cloud service requester can need to access different cloud service providers for many times. As a result, the system resources are wasted, and the system efficiency is low. Through this embodiment, the cloud service broker selects and/or adapts a proper cloud service provider for the cloud service requester according to the stored cloud service information of various cloud service providers, so that the cloud service requester can avoid accessing different cloud service providers for many times. The system resources are effectively saved, and the system efficiency is improved. 
         [0046]    The embodiment of this disclosure provides a cloud service consuming interface message packet, which is used by the cloud service requester to access the cloud service.

The information contents of the cloud service consuming interface message packet are described in at least one of the following formats: XML, JSON and other specific formats. 
         [0048]    The cloud service requester can carry an XML message packet, a JSON message packet or message packets in other specific formats in ways of HTTP, SIP, REST, SOAP, XHTML5, API and specific command, to access and/or control the cloud service and/or resource information provided by the cloud service provider through the cloud service broker. 
         [0049]    Further, the cloud service requester accessing and/or controlling the cloud services provided by the cloud service provider through the cloud service broker can include at least one of the following operation ways: creating, reading, updating, deleting, executing, copying, moving, selecting, collecting or the like. When the cloud service requester adopts HTTP, POST, GET, PUT, DELETE, COPY, HEAD, MKCOL, MOVE, OPTIONS or the like can be used.
