一种地址空间推荐方法、装置及相关设备
本申请要求于2022年1月24日递交中国国家知识产权局、申请号为202210081617.5，发明名称为“一种地址空间推荐方法、装置及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及互联网技术领域，尤其涉及一种地址空间推荐方法、装置及相关设备。
背景技术
随着云服务部署的增多，越多越多的用户(如企业等)期望在全球范围内的不同虚拟私有云(virtual private cloud，VPC)之间实现互连。以VPC为例，通常情况下，当不同VPC之间相互隔离时(即相互之间不存在数据交互)，不同VPC所使用的地址空间可以存在重叠，包括互联网协议版本4(Internet Protocol Version 4，IPV4)地址空间和/或互联网协议版本6(Internet Protocol Version 6，IPV6)地址空间等；而当不同VPC之间进行互连时，需要保证不同VPC所使用的地址空间不存在重叠，以避免数据包因为不同VPC之间的地址空间重叠而无法转发，如出现回环路由等。
目前，用户在创建/更新VPC时，通常会根据与该VPC互连的其它VPC所使用的地址空间，为该VPC手动配置不重叠的地址段，以避免出现地址冲突。但是，实际应用场景中，与该VPC互连的其它VPC的数量可能较多，如包括几十甚至几百个VPC等。此时，由用户为VPC人工配置不与其它VPC存在地址冲突的地址空间，不仅配置难度较大、配置效率较低，而且配置VPC的地址空间容易出现错误，从而影响该VPC与其它VPC之间建立互连关系。
发明内容
本申请实施例提供一种地址空间推荐方法、装置及相关设备，以降低配置VPC的难度、提高配置效率、降低配置地址空间出现错误的可能性。
第一方面，本申请实施例提供一种地址空间推荐方法，该方法例如可以是由地址空间推荐装置执行，具体的，在为VPC推荐可用的地址空间时，地址空间推荐装置先获取客户端发送的针对第一VPC的地址空间推荐请求，该地址空间推荐请求包括第一联盟关系的标识，然后响应该地址空间推荐请求，确定与第二VPC对应的第二地址空间不同的第一地址空间，该第一VPC与第二VPC具有该第一联盟关系，从而所确定的第一地址空间与第二地址空间不存在重叠，最后，地址空间推荐装置向客户端输出该第一地址空间。
由于在创建或者更新VPC时，地址空间推荐装置可以自动为该VPC推荐联盟关系中不与其它VPC存在地址冲突的第一地址空间，从而无需用户手动为该VPC配置地址空间。如此，不仅可以降低用户配置VPC的难度、提高配置效率，而且，基于自动推荐的第一地址空间对VPC进行配置，可以有效降低配置VPC出错的可能性，有助于建立该VPC与其它VPC之间的互联关系。
在一种可能的实施方式中，地址空间推荐请求还包括地址约束条件，如可以由用户指定该地址约束条件等，则所确定的第一地址空间满足该地址约束条件。如此，为用户自动 推荐的第一地址空间不仅与联盟关系中的其它VPC对应的地址空间不存在重叠，而且，该第一地址空间还符合用户的要求，如满足用户在地址空间大小、地址前缀等方面的要求。
在一种可能的实施方式中，地址约束条件用于指示地址空间的大小，则地址空间推荐装置在响应地址空间推荐请求时，具体可以是根据该地址空间推荐请求中的第一联盟关系的标识，确定第一联盟关系中的第一可用地址空间以及第二可用地址空间，该第一可用地址空间的大小小于第二可用地址空间的大小，然后根据该地址空间推荐请求中的地址约束条件，优先从第一可用地址空间中确定第一地址空间。如此，这样，当后续创建/更新的其它VPC需要配置更大的地址空间时，地址空间推荐装置可以从相对较大的第二可用地址空间中为其分配其所需的地址空间，提高地址空间分配的合理性以及地址空间的利用率。
在一种可能的实施方式中，地址空间推荐装置还可以提供配置界面，该配置界面可以通过客户端呈现给用户，然后，地址空间推荐装置可以响应于用户在该配置界面上针对第一VPC的配置操作，获得第一联盟关系的标识以及该地址约束条件。如此，地址空间推荐装置可以支持用户对VPC在联盟关系以及地址约束条件的灵活配置，提高用户体验。
在一种可能的实施方式中，地址空间推荐请求还包括第二联盟关系的标识，则地址空间推荐装置所确定的第一地址空间不仅与第一联盟关系中的各个VPC分别对应的地址空间均不存在重叠，而且，该第一地址空间与第二联盟关系中的各个VPC分别对应的地址空间也均不存在重叠。如此，地址空间推荐装置为VPC所自动推荐的地址空间，可以在存在通信的两个联盟关系中不存在地址冲突。
在一种可能的实施方式中，地址空间推荐装置还可以提供推荐界面，该推荐界面通过客户端呈现给用户，并且，该推荐界面中包括第一地址空间。如此，地址空间推荐装置可以将确定的第一地址空间呈现给用户，以便由于用户获知为VPC推荐的地址空间，提高用户体验。
在一种可能的实施方式中，地址空间推荐装置还可以响应用户针对该第一地址空间的更换操作，确定第二地址空间，该第二地址空间与第一地址空间不重叠，并且，该第二地址空间与第一联盟关系中的各个VPC分别对应的地址空间均不重叠，然后，地址空间推荐装置向客户端输出该第二地址空间。如此，可以在用户不满意之前推荐的第一地址空间后，再次为用户推荐其它可用的地址空间，以使得重新推荐后的第二地址空间能够满足用户的使用需求，从而可以进一步方便用户对VPC进行地址空间的配置，提高用户体验。
第二方面，基于与第一方面的方法实施例同样的发明构思，本申请实施例提供了一种地址空间推荐装置。该装置具有实现上述第一方面的各实施方式对应的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块。
第三方面，本申请实施例提供一种计算设备，包括：处理器和存储器；该存储器用于存储指令，当该计算设备运行时，该处理器执行该存储器存储的该指令，以使该计算设备执行上述第一方面或第一方面的任一实现方式中的地址空间推荐方法。需要说明的是，该存储器可以集成于处理器中，也可以是独立于处理器之外。装置还可以包括总线。其中，处理器通过总线连接存储器。其中，存储器可以包括可读存储器以及随机存取存储器。
第四方面，本申请实施例还提供一种可读存储介质，所述可读存储介质中存储有程序 或指令，当其在计算机上运行时，使得上述第一方面或第一方面的任一实现方式中的地址空间推荐方法被执行。
第五方面，本申请实施例还提供一种包含指令的计算机程序产品，当其在计算机上运行时，使得计算机执行上述第一方面或第一方面的任一实现方式中的任意地址空间推荐方法。
另外，第二方面至五方面中任一种实现方式所带来的技术效果可参见第一方面中不同实现方式所带来的技术效果，或者可参见第二方面中不同实现方式所带来的技术效果，此处不再赘述。
附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请中记载的一些实施例，对于本领域普通技术人员来讲，还可以根据这些附图获得其他的附图。
图1为本申请实施例提供的一示例性地址空间推荐系统的结构示意图；
图2为本申请实施例提供的地址空间推荐方法的流程示意图；
图3为本申请实施例提供的一示例性配置界面示意图；
图4为本申请实施例提供的IPV4地址格式的示意图；

图6为本申请实施例提供的又一示例性推荐界面示意图；
图7为本申请实施例提供的一种地址空间推荐装置的结构示意图；
图8为本申请实施例提供的一种计算设备的硬件结构示意图。
具体实施方式
参见图1，为一示例性地址空间推荐系统的结构示意图。如图1所示，地址空间推荐系统100可以包括客户端101、服务平台102。并且，客户端101以及服务平台102之间可以进行数据交互，如通过超文本传输协议(Hypertext Transfer Protocol，HTTP)或者其他网络协议进行数据通信等。
其中，客户端101，可以是服务平台102对外提供的网络浏览器，用于与用户进行交互；或者，客户端101可以是运行在用户终端上的应用程序(application)等。在地址空间推荐系统100中，客户端101的数量可以是一个或者多个，本实施例对此并不进行限定。服务平台102可以通过一个或者多个计算设备(如服务器等)进行构建，实际应用时，服务平台102还可以包括存储设备等其它设备。图1中以通过多个服务器构建服务平台102为例进行示例性说明，并且用户可以通过客户端101在服务平台102上创建VPC或者微服务(microservices)。其中，VPC，是指用户创建的属于自己的私有网络，相互隔离的VPC之间不互连，地址空间可完全重叠，而互连的VPC之间地址空间不存在重叠。微服务，是指由基于业务构建并且能够独立部署的小服务，一个或者多个微服务可以构成应用程序。
以创建VPC为例，当在服务平台102上创建新的VPC，并且所创建的VPC与其它VPC存在互联时，用户通常需要通过客户端101手动为该VPC配置地址空间，并且所配置的地址空间与其它VPC所使用的地址空间不存在重叠，以避免发生地址冲突而影响VPC之间的数据通信。但是，实际应用时，与该新创建的VPC存在互联的其它VPC的数量可能较 多，这要求用户需要了解众多VPC分别对应的地址空间，并人工分析出不与每个VPC所使用的地址空间存在重叠的地址空间，从而将该地址空间配置给新创建的VPC。这种人工为VPC配置可用的地址空间的方式，不仅配置难度较大、配置效率较低，而且配置VPC的地址空间容易出现错误，如容易与其中一个VPC所使用的地址空间存在部分重叠等，从而影响该VPC与其它VPC之间建立互连关系。
基于此，本申请实施例提供了一种地址空间推荐方法，该地址空间推荐方法可以由地址空间推荐装置103执行，该地址空间推荐装置103可以部署于服务平台102中。示例性地，地址空间推荐装置103可以通过软件或者硬件实现。当通过软件实现时，地址空间推荐装置103可以是运行在计算设备上的计算机程序，如软件开发工具包(software development kit，SDK)等。当通过硬件实现时，地址空间推荐装置103可以是服务器等计算设备，并且该计算设备上运行了计算机程序，以使得地址空间推荐装置103具有自动推荐地址空间的功能。或者，地址空间推荐装置103可以是利用专用集成电路(application-specific integrated circuit，ASIC)实现、或可编程逻辑器件(programmable logic device，PLD)实现的设备等。其中，上述PLD可以是复杂程序逻辑器件(complex programmable logical device，CPLD)、现场可编程门阵列(field-programmable gate array，FPGA)、通用阵列逻辑(generic array logic，GAL)或其任意组合实现。
当用户通过客户端101请求创建或者更新VPC时，服务平台102可以接收客户端101发送的针对VPC的地址空间推荐请求，该地址空间推荐请求中携带有该VPC所属的联盟关系的标识。然后，服务平台102可以调用地址空间推荐装置103响应该地址空间推荐请求，确定该联盟关系中与其它VPC对应的第二地址空间不同的第一地址空间，并向客户端101输出该第一地址空间，实现为新创建/更新的VPC自动推荐可用的地址空间。
由于在创建或者更新VPC时，可以自动为该VPC推荐联盟关系中不与其它VPC存在地址冲突的第一地址空间，从而无需用户手动为该VPC配置地址空间。如此，不仅可以降低用户配置VPC的难度、提高配置效率，而且，基于自动推荐的第一地址空间对VPC进行配置，可以有效降低配置VPC出错的可能性，有助于建立该VPC与其它VPC之间的互联关系。
需要说明的是，上述示例中是以地址空间推荐装置103部署于服务平台102为例，实际应用时，地址空间推荐装置103也可以是独立于服务平台102进行部署，如图1所示。此时，当用户通过客户端101在服务平台102上申请创建/更新VPC时，服务平台102可以生成地址空间推荐请求，将其发送给地址空间推荐装置103，并将地址空间推荐装置103所反馈的第一地址空间发送给客户端101，实现为VPC自动推荐可用的地址空间。并且，在服务平台102内部或者外部可以配置数据库，其中，配置于服务平台102内部的数据库可以称之为本地数据库，配置于服务平台102外部的数据库可以称之为云端数据库，并且，该本地数据库或者云端数据库可以用于存储数据，如存储各个联盟关系所包括的VPC信息、各个联盟关系所对应的剩余可用的地址空间等。
值得注意的是，图1所示的系统架构仅作为一种示例，并不用于限定其具体实现局限于该示例。例如，在其它可能的系统架构中，地址空间推荐系统100还可以包括更多其它功能的装置，以为服务平台102提供更加丰富的功能，本实施例对此并不进行限定。
为使本申请的上述目的、特征和优点能够更加明显易懂，下面将结合附图对本申请实施例中的各种非限定性实施方式进行示例性说明。显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
如图2所示，为本申请实施例中一种地址空间推荐方法的流程示意图，该方法可以应用于如图1所示的地址空间推荐系统100中，并可以由该地址空间推荐系统100中的地址空间推荐装置103执行。实际应用时，该方法也可以是应用于其它可适用的地址空间推荐系统中。为便于理解与描述，下面以地址空间推荐装置103执行该方法为例进行示例性说明，该方法具体可以包括：
S201：地址空间推荐装置103获取客户端101发送的针对第一VPC的地址空间推荐请求，该地址空间推荐请求包括第一联盟关系的标识。
本实施例中，当用户通过客户端101在服务平台102上创建/更新VPC时，服务平台102可以通过地址空间推荐装置103为该VPC确定可用的地址空间。
实际应用时，服务平台102可以向客户端101提供操作界面，并通过客户端101向用户呈现该操作界面。这样，用户可以在该操作界面上申请创建或者更新VPC。为便于区分与描述，以下将用户所申请创建或者更新的VPC称之为第一VPC。
然后，基于用户创建/更新第一VPC的请求，服务平台102可以向客户端101提供配置界面，从而客户端101所呈现的界面由上述操作界面切换至该配置界面。这样，用户可以在该配置界面上针对第一VPC执行相应的配置操作，获得第一VPC所属的联盟关系的标识。例如，客户端101所呈现的配置界面可以如图3所示，用户可以在该配置界面上输入所要创建的第一VPC所属的第一联盟关系的名称。其中，在创建第一VPC之前，该第一联盟关系中可以包括一个或者多个VPC，并且，该第一联盟关系可以由用户进行创建，或者由其它用户进行预先创建。当然，当用户之前未创建第一联盟关系时，用户也可以是在该配置界面上新建该第一联盟关系，如通过点击配置界面上的“新建联盟关系”控件来创建新的联盟关系等。当在已创建的第一联盟关系中添加第一VPC时，该第一VPC可以与该第一联盟关系中的其它VPC进行互连。本实施例中，属于同一联盟关系的任意VPC之间可以进行互连，相应的，该联盟关系下的不同VPC之间所使用的地址空间不存在重叠。当在第一联盟关系中创建第一VPC时，分配给该第一VPC的地址空间与该第一联盟关系中的其余VPC(以下称之为第二VPC)所具有的第二地址空间不存在重叠，以避免影响第一VPC与第二VPC之间的通信。
接着，客户端101可以将用户配置的第一联盟关系的标识发送给服务平台102，由服务平台102生成包括该第一联盟关系的标识的地址空间推荐请求，并将其发送给地址空间推荐装置103，以请求地址空间推荐装置103为该第一VPC确定可用的地址空间。本实施例中，地址空间，是指基于互联网协议(Internet Protocol，IP)的一个或者多个IP地址，具体可以是IPV4地址和/或IPV6地址。
进一步地，用户还可以在该配置界面上对第一VPC进行基础配置，如图3中，用户可以配置VPC的名称以及该VPC所包括的可用区(availability zone)或分区(region)等。 另外，用户还可以在配置界面上输入地址约束条件，以约束该第一VPC可用的地址范围。示例性地，该地址约束条件例如可以指示地址空间的大小，和/或指示地址的固定前缀等。例如，用户可以在图3所示的配置界面上输入第一VPC对应的地址前缀，以固定服务平台102为该第一VPC配置的各个地址的前缀。如用户可以配置第一VPC对应的IPV4地址的前缀为“192.16.X.X”，从而后续服务平台102为该第一VPC配置的各个IPV4地址的前缀均相同，如192.16.0.0～192.16.255.255等。实际应用时，用户还可以在配置界面上为第一VPC配置其它信息，如地址空间的大小、地址类型(如IPV4地址、IPV6地址)等，本实施例对此并不进行限定。
S202：地址空间推荐装置103响应地址空间推荐请求，确定与第二VPC对应的第二地址空间不同的第一地址空间，该第一VPC与第二VPC具有该第一联盟关系。
S203：地址空间推荐装置103向客户端101输出第一地址空间。
具体实现时，地址空间推荐装置103可以响应接收到的地址空间推荐请求，从中解析出第一联盟关系的标识，并查找出与该第一联盟关系所对应的可用的地址空间。其中，可用的地址空间是指与该第一联盟关系中的任意VPC所使用的地址空间均不存在重叠的地址空间。如此，地址空间推荐装置103可以从可用的地址中确定出第一地址空间，并将其分配给第一VPC。举例来说，假设第一联盟关系中包括VPC1以及VPC2，第一联盟关系对应的所有可被分配的IPV4地址空间为128.1.0.1～191.254.255.254，并且，VPC1所分配到的IPV4地址空间为128.1.0.1～150.255.255.255，VPC2所分配到的IPV4地址空间为151.0.0.0～160.255.255.255，此时，剩余可用的IPV4地址空间为161.0.0.0～191.254.255.254。当用户申请在该第一联盟关系中新建第一VPC时，服务平台102可以从剩余可用的IPV4地址空间161.0.0.0～191.254.255.254中，将161.0.0.0～165.254.255.254作为第一地址空间分配给第一VPC。如此，地址空间推荐装置103所确定出的第一地址空间可以与第一联盟关系中各个VPC所使用的地址空间均不存在重叠。需要说明的是，步骤S202中所描述的地址空间不同，具体是指第一地址空间与第二地址空间不存在重叠，以此避免第一VPC与第二VPC之间存在地址冲突。
实际应用时，第一联盟关系对应的可用的地址空间，可以存储于第一数据库(data base，DB)中，该第一数据库可以部署于服务平台102本地，从而地址空间推荐装置103可以通过访问数据平台102的本地数据库，获得该第一联盟关系对应的可用地址空间。或者，第一数据库也可以是独立于服务平台102进行部署，如部署于云端等，本实施例对此并不进行限定。
在一些可能的实施方式中，针对所要创建或者更新的每个VPC，地址空间推荐装置103可以为该VPC分配固定大小的地址空间，或者，地址空间推荐装置103也可以由用户通过配置地址约束条件进行指定。比如，当用户在配置界面上输入地址约束条件时，若该地址约束条件指示分配给第一VPC的地址空间大小(即包括的地址的数量)，则地址空间推荐装置103可以从第一联盟关系对应的可用的地址空间中，确定出相应大小的第一地址空间。
进一步地，地址空间推荐装置103还可以采用贪心算法确定分配给第一VPC的第一地址空间，以减少第一联盟关系对应的可用地址空间的碎片率。具体地，当第一联盟关系中的多个VPC分配到各自对应的地址空间时，该第一联盟关系对应的可用地址空间可能包括 多个不连续的地址段，从而地址空间推荐装置103可以优先从较小的地址段中为第一VPC分配第一地址空间。例如，假设地址空间推荐装置103根据第一联盟关系的标识，查找到该第一联盟关系对应的可用的地址空间包括不重叠的第一可用地址空间以及第二可用地址空间，并且，该第一可用地址空间的大小小于第二可用地址空间的大小，则地址空间推荐装置103可以根据地址约束条件，优先从第一可用地址空间中确定分配给第一VPC的第一地址空间。这样，当后续创建/更新的其它VPC需要配置更大的地址空间时，地址空间推荐装置103可以从相对较大的第二可用地址空间中为其分配其所需的地址空间，提高地址空间分配的合理性以及地址空间的利用率。
在其它可能的实施方式中，用户所配置的地址约束条件也可以指示分配给第一VPC的地址前缀，从而地址空间推荐装置103可以从可用的地址空间中，确定出满足地址约束条件所指示的地址前缀的第一地址空间，以满足用户对于该地址空间的需求。实际应用时，用户所指定的地址前缀，可以作为用户的私有网络地址段的标识。进一步地，该地址前缀，还可以对实现VPC的AZ或者分区进行标识。以IPV4地址为例，分配给第一VPC的每个IPV4地址可以通过32比特(bit)进行表示，如图4所示。其中，第1位至第Y位即为IPV4地址的前缀，并且第1位至第X位(X为大于1的正整数)可以用于标识用户的私有网络地址段，第X+1位至第Y位可以用于标识实现VPC的AZ/分区，Y为大于等于X的正整数。当Y大于X时，每个IPV4地址的前缀可以携带有AZ或者分区的标识信息；而当Y等于X时，每个IPV4地址的前缀可以无需标识该AZ或者分区。并且，在用户指定地址前缀的情况下，地址空间推荐装置103也可以基于贪心算法优先从较小的地址段中为第一VPC确定合适地址空间。
上述实施方式中，是以地址空间推荐装置103在一个联盟关系中创建/更新第一VPC时确定第一地址空间为例，实际应用时，服务平台102可以为用户在多个不同的联盟关系中创建/更新不同的VPC。此时，在每个联盟关系中创建/更新VPC时，地址空间推荐装置103均可以采用上述类似方式确定分配给该VPC的地址空间，并且所分配的地址空间与该联盟关系中其它VPC所分配到的地址空间不存在重叠。值得注意的是，不同联盟关系中的VPC之间，可以不存在互连，也即不同联盟关系中的VPC可以相互隔离，因此，每个联盟关系对应的可分配的全部地址空间可以存在重叠。比如，针对相互隔离的联盟关系1以及联盟关系2，联盟关系1对应的全部可用的IPV4地址空间可以是128.1.0.1～191.254.255.254，联盟关系2对应的全部可用的IPV4地址空间也可以是128.1.0.1～191.254.255.254。相应的，当在联盟关系1中新建VPCa时，地址空间推荐装置103为该VPCa分配的IPV4地址空间可以是128.1.0.1～150.255.255.255；在联盟关系2中新建VPCb时，地址空间推荐装置103为该VPCb分配的IPV4地址空间也可以是128.1.0.1～150.255.255.255等。
而在其它实施方式中，不同联盟关系中的VPC之间可以通过部分VPC进行互连，具体的，当地址空间推荐请求同时包括第一联盟关系以及第二联盟关系的标识时，表征第一VPC同时属于第一联盟关系以及第二联盟关系，此时，地址空间推荐装置103为第一VPC分配的第一地址空间，不仅与第一联盟关系中的各个VPC分别对应的地址空间均不重叠，而且与所述第二联盟关系中的各个VPC分别对应的地址空间均不重叠。比如，假设用户1 可以创建联盟关系1并且在该联盟关系1中新建VPCa 1和VPCa 2，用户2可以创建联盟关系2并且在该联盟关系2中新建VPCb 1和VPCb 2，当用户1期望联盟关系1中的VPC与联盟关系中2中的VPC可以进行互连时，用户1可以在联盟关系1以及联盟关系2中同时创建VPCc 1。这样，在联盟关系1中，VPCc 1可以与VPCa 1和VPCa 2进行互连，并且，在联盟关系2中，VPCc 1可以与VPCb 1和VPCb 2进行互连。如此，可以实现两个联盟关系之间的数据交互。值得注意的是，在联盟关系1以及联盟关系2中新建VPCc 1时，地址空间推荐装置103为该VPCc 1分配的地址空间，不仅与联盟关系1中的VPCa 1和VPCa 2所分配到的地址空间均不存在重叠，而且，与联盟关系1中的VPCb 1和VPCb 2所分配到的地址空间也不存在重叠。
实际应用时，当地址空间推荐系统100支持多个用户在多个联盟关系中分别进行VPC的创建/更新时，地址空间推荐系统100还可以对多个联盟关系的信息进行管理。具体地，地址空间推荐系统100中还可以部署第二数据库，该第二数据库可以部署于服务平台102本地，也可以部署于云端，并且该第二数据库可以用于存储各个联盟关系的相关信息，如联盟关系的标识、联盟关系中各个VPC的标识、VPC所属用户、VPC所分配到的地址空间等，从而地址空间推荐系统100可以通过访问第二数据库，获取属于各个用户的联盟关系的相关信息，以便根据该信息对属于各个用户的VPC进行运维、方便用户查询联盟关系的信息。
地址空间推荐装置103在输出第一地址空间后，可以将其反馈给服务平台102，从而服务平台102可以直接将第一VPC的地址空间配置为该第一地址空间，并将第一地址空间通过客户端101呈现给用户，以便由用户获知服务平台102为该第一VPC配置的地址空间。在进一步可能的实施方式中，在确定为第一VPC配置地址空间之前，还可以由用户确定该第一VPC的地址空间是否为第一地址空间。具体的，本实施例还可以包括：
S204：服务平台102提供推荐界面，该推荐界面通过客户端101呈现给用户，并且，该推荐界面中包括地址空间推荐装置103输出的第一地址空间。
在一种可能的示例中，服务平台102可以提供如图5所示的推荐界面，该推荐界面中包括向用户推荐的第一地址空间。同时，该推荐界面中还可以包括“确认”控件以及“再次推荐”控件。实际应用时，图5所示的推荐界面与图3所示的配置界面可以为两个独立的界面，也可以是合并为同一界面，如图6所示，用户可以在该界面上对所要创建/更新的第一VPC进行相应的配置时，还可以查看到地址空间推荐系统100自动推荐的地址空间，本实施例对此并不进行限定。当用户在推荐界面上点击该“确认”控件时，服务平台102确定将第一VPC的地址空间配置为第一地址空间；而当用户在该推荐界面上点击“再次推荐”控件时(如当前推荐的第一地址空间不符合用户对于地址空间的未来规划等)，服务平台102可以指示地址空间推荐装置103重新为该第一VPC确定地址空间。此时，地址空间推荐装置103还可以进一步执行下述步骤：
S205：地址空间推荐装置103响应用户针对第一地址空间的更换操作，确定第二地址空间，其中，该第二地址空间与所述第一地址空间不重叠，并且，该第二地址空间与第一联盟关系中的各个VPC分别对应的地址空间均不重叠。
S206：地址空间推荐装置103向客户端101输出该第二地址空间。
其中，用户针对该第一地址空间的更换操作，例如可以是上述点击“再次推荐”空间的操作，或者可以是其它触发地址空间推荐装置103重新推荐地址空间的操作等，本实施例对此并不进行限定。
当用户请求重新推荐地址空间时，地址空间推荐装置103可以从第一联盟关系对应的可用地址空间中，重新查找出与第一地址空间不重叠的第二地址空间。其中，地址空间推荐装置103确定第二地址空间的具体实现方式，与上述第一确定目标地址空间的具体实现方式类似，可参见前述实施例的相关之处描述。值得注意的是，重新查找出的第二地址空间仍然需要满足与该联盟关系中的其它VPC所分配到的地址空间不存在重叠的基础要求。实际应用时，在用户请求重新推荐地址空间之前，用户还可以向服务平台102输入地址信息(如地址前缀、地址空间大小、地址连续性等)，并由地址空间推荐装置103输出满足该地址信息的第二地址空间，以便于重新推荐的第二地址空间能够符合用户的预期。
在地址空间推荐装置103输出第二地址空间后，服务平台102可以将该第二地址空间呈现在图5或者图6所示的推荐界面中，以便由用户进一步确定是否将第一VPC的地址空间配置为该第二地址空间。当用户在推荐界面中点击“确认”控件后，服务平台102确定将第一VPC的地址空间配置为该第二地址空间；而当用户在推荐界面中点击“再次推荐”控件后，服务平台102可以再次为用户推荐新的地址空间。
进一步地，当用户释放第一联盟关系中的一个或者多个VPC时，地址空间推荐装置103还可以回收地址空间，具体可以是将已分配给该第一VPC的地址空间进行释放，并将其作为可用的地址空间添加至第一数据库中。这样，当后续用户创建或者更新VPC时，地址空间推荐装置103可以从第一数据库中将该地址空间分配给所要创建或者更新的VPC。
值得注意的是，本实施例中，是以地址空间推荐装置103与服务平台102作为两个独立的实体对自动推荐地址空间的实现过程进行示例性说明，在其它实施例中，地址空间推荐装置103也可以部署于服务平台102上，此时，上述实施例中服务平台102所执行的部分或者全部动作，具体由地址空间推荐装置103进行执行，本实施例对此并不进行限定。
并且，本实施例中是以地址空间推荐装置103为VPC自动推荐可用的地址空间为例，在其它可能的实施例中，地址空间推荐装置103也可以是为用户请求创建或者更新的微服务自动推荐可用的地址空间，其具体实现方式与上述实施例中介绍的为VPC自动推荐可用的地址空间的具体过程类似，可参见上述过程进行理解，在此不做赘述。
