本申请引用于2019年09月24日递交的名称为“一种边缘应用管理方法及系统”的第201910904574.4号中国专利申请,其通过引用被全部并入本申请。
技术领域
本申请涉及计算机应用技术领域,特别涉及一种边缘应用管理方法及系统。
背景技术
随着物联网、视频智能分析、人工智能等新兴应用的产生,以及5G时代的即将到来,推动了边缘计算的兴起。在此背景下,服务提供商为了提高服务的品质,会在运营商边缘侧部署边缘应用,边缘应用也就是一套用于对外提供服务或特定功能的系统的统称,可以由弹性云服务器、部署在弹性云服务器上的应用服务、保存系统的存储数据以及负载均衡服务器等组成。
相关技术中,服务提供商可以通过使用现有的公有云模式,来搭建自己的边缘应用,从而将边缘应用部署到运营商边缘侧。具体的,当服务提供商需要在公有云提供商提供的多个边缘云节点(或者云数据中心)上部署自己的边缘应用时,则需要在公有云控制台上切换多个边缘云节点(或者云数据中心),进而创建计算、存储、网络等资源;待资源创建好后,再登录相关的弹性云服务器部署自己的边缘应用,实现对边缘应用的管理。
也就是说,假如服务提供商需要在10个边缘云节点部署边缘应用时,同样的操作需要执行10次。而有当服务提供商需要部署20个、30个甚至更多边缘云节点的时候,服务提供商的工作量就会成倍增加,导致降低服务提供商对 云平台使用的满意度。

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的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图4是本申请实施例提供的一种计算机设备的结构示意图。
具体实施例
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例提供了一种边缘应用管理方法,该方法应用于图1所示的系统框架中,该系统框架包括:云数据中心、边缘云节点以及边缘应用管理系统。
上述云数据中心和边缘云节点所实现的功能是基本相同的,区别在于边缘云节点处于网络的边缘侧,即两者所处的地理位置不同,基于此,上述云数据中心与边缘云节点均可以为IaaS(Infrastructure as a Service,基础设施即服务)。
上述边缘应用管理系统包括:配置管理模块,用于采集指定云数据中心逻辑范围内用户隔离资源的资源配置以及系统应用数据并形成边缘应用模板,上述弹性云服务器可以为IaaS内的VPC(virtual private cloud,虚拟私有云)内隔离的弹性云服务器;并提供弹性云服务器的操作命令,如重启、停止、启动、重置密码等功能命令。
上述弹性云服务器也可称之为虚拟机,即指通过软件模拟的具有完整硬件系统功能的、运行在一个完全隔离环境中的完整计算机系统。
数据同步模块,用于提供弹性云服务器的系统镜像、云硬盘的数据同步,保证数据同步的准确性以及高效性。
资源编排模块,用于根据边缘应用模板,调用指定云数据中心接口,并根据资源的依赖顺序,创建满足边缘应用模板要求的资源配置以及组网环境;根据监控模块产生的告警事件,对弹性云服务器进行故障自愈、弹性伸缩的操作。
镜像升级模块,用于弹性云服务器系统镜像的升级,保证升级准确、高效执行。
监控告警模块向用户提供监控告警策略,用户可以在监控告警模块提供的监控告警策略中进行选择并设置,相应的,监控告警模块,用于周期性的采集边缘云资源的性能以及监控数据,根据用户预定义的故障处理策略、弹性伸缩策略,当阈值满足策略的时候,触发策略的回调接口,通知资源编排模块进行相应的处理。
流量调度模块,用于在边缘侧用户接入边缘应用管理系统的时候,就近访问靠近用户侧的边缘云节点管理的边缘应用,具体的,当用户请求访问边缘应用管理系统的域名的时候,会根据用户所在的地理位置,解析最近的边缘云节点,将用户请求引流到最近边缘云节点管理的边缘应用,实现流量调度。
在实施中,边缘应用管理系统中配置管理模块调用云数据中心接口查询云数据中心内用户隔离资源的资源信息,得到资源配置信息;对弹性云服务器的系统盘做镜像、数据盘做备份,得到系统应用数据;利用资源配置信息和系统应用数据生成边缘应用模版。
数据同步模块将边缘应用模版中的弹性云服务器的系统镜像、云硬盘的数据同步至边缘云节点。
资源编排模块根据边缘应用模板,调用云数据中心接口,并根据资源的依赖顺序,在边缘云节点内创建满足模板要求的资源配置以及组网环境的能力,实现边缘应用的管理。
下面将结合具体实施例,对图2所示的边缘应用管理方法的流程进行详细的说明,内容可以如下:
步骤200,生成用于部署边缘云节点管理的边缘应用的边缘应用模版。
其中,边缘应用模版包含:用于部署边缘云节点资源的资源配置信息和云数据中心内弹性云服务器的系统应用数据。
上述资源配置信息可以包括:弹性云服务器规格、弹性云服务器秘钥、弹性云服务器网络、弹性云服务器的安全组、负载均衡器配置、公网线路、云硬盘配置、共享存储(NAS,Network Attached Storage)配置等信息。
上述系统应用数据可以包括:系统盘镜像、数据盘数据等。
一种实现方式中,上述步骤200可以包含以下步骤A1-A3。
步骤A1,调用云数据中心接口查询云数据中心内用户隔离资源的资源信息,得到资源配置信息。
在实施中,可以预先将各个云数据中心的调用地址注册到边缘应用管理系统,这样就可以实现对各个云数据中心的资源进行统一管理,一种实现方式中,用户可以在云数据中心内隔离出各个资源的资源配置信息,比如,用户隔离出弹性云服务器、负载均衡器、存块储、共享存储以及弹性云服务器关联的公网配置等资源配置信息,相应的,边缘应用管理系统则可以通过调用云数据中心接口来查询用户隔离资源的资源配置信息。
步骤A2,对弹性云服务器列表中包含的弹性云服务器的系统盘做镜像、数据盘做备份,得到系统应用数据。
弹性云服务器列表也就是用户指定用于提供系统应用数据的弹性云服务器的列表,在实施中,用户可以通过弹性云服务器列表来指定一个或多个用于提供系统应用数据的弹性云服务器。
步骤A3,利用资源配置信息和系统应用数据生成边缘应用模版。
步骤210,将系统应用数据同步至待部署边缘云节点。
在实施中,考虑到将系统镜像、数据盘数据同步到各个边缘云节点需要大量的流量,如果使用串行拷贝的方式,性能慢效率低;而通过并行拷贝则容易将云数据中心的带宽占满的问题。一种实现方式中,可以将待部署边缘云节点中已经完成同步的边缘云节点作为数据源;将数据源内的系统应用数据同步至待部署边缘云节点中未进行同步的边缘云节点,以此来提高同步效率。
比如,将云数据中心数据A中的系统镜像、数据盘数据,拷贝到边缘云 节点B、C、D中,可以先由A拷贝到节点B,再以A、B为数据源,同时从A拷贝到C、B拷贝到D。
另一种实现方式中,还可以P2P文件共享协议来完成系统镜像、数据盘数据的拷贝,加快传输效率。
步骤220,按照资源配置信息部署待部署边缘云节点的资源,实现边缘应用的管理。
在实施中,可以调用云数据中心的接口将各个资源配置信息转换为边缘云节点可执行的指令,然后根据资源配置信息包含的各个资源的依赖顺序,以此创建资源,最终创建所有待部署边缘云节点管理的边缘应用所需的资源,完成边缘应用的管理,也就是平滑地将云数据中心云部分业务快速复制、迁移至边缘云节点。
一种实现方式中,上述步骤220可以包含以下步骤B1-B3。
步骤B1,获取待部署边缘云节点的可用资源信息。
可用资源信息也就是待部署边缘云节点实际拥有资源的信息,比如,可用资源信息可以包含表示内存资源大小、表示带宽资源大小、表示CPU核数以及表示存储容量等信息。
步骤B2,对比可用资源信息与资源配置信息,确定可用资源信息是否满足资源配置信息所定义的资源要求。
步骤B3,在可用资源信息满足资源配置信息所定义的资源要求的情况下,按照资源配置信息部署待部署边缘云节点的资源。
可用资源信息满足资源配置信息所定义的资源要求,也就是可用资源信息的值不小于资源配置信息的值,比如,资源配置信息中内存信息为2G,可用资源信息中内存信息为4G,则表明可用资源信息满足资源配置信息所定义的资源要求。当可用资源信息满足资源配置信息所定义的资源要求时,可以直接利用资源配置信息来部署边缘云节点。
另一种实现方式中,可用资源信息满足资源配置信息所定义的资源要求 时,可用资源信息的值会大于等于资源配置信息的值,因此为了充分利用待部署边缘云节点的可用资源,可以利用可用资源信息来更新资源配置信息,然后再按照资源配置信息部署待部署边缘云节点的资源;也就是直接使用待部署边缘云节点实际拥有资源进行部署。比如,资源配置信息中内存信息为2G,可用资源信息中内存信息为4G,则将待部署边缘云节点的内存部署为4G,从而充分利用内存资源。
应用本申请实施例提供的方案,能够通过边缘应用模版来实现对边缘云节点管理的边缘应用进行统一的部署,降低用户部署工作量以及边缘应用的管理难度。
在实施中,需要对云数据中心内的弹性云服务器进行批量升级时,可以利用已经完成升级的弹性云服务器的系统镜像来得到增量数据,利用增量数据对未升级的弹性云服务器进行批量升级。以此来加快数据的传输速率进而加快弹性云服务器的升级效率。
在实施中,可以更新边缘应用模版内系统应用数据包含的系统镜像,然后利用更新后的系统镜像来实现对各个边缘云节点对应的弹性云服务器进行批量升级,具体的,可以包含以下步骤C1-C4。
步骤C1,更新边缘应用模版内系统应用数据包含的系统镜像,得到新系统镜像。
步骤C2,根据新系统镜像和弹性云服务器升级之前的原始系统镜像得到增量数据。
增量数据也就是新系统镜像相较于原始系统镜像发生变化的数据,比如,增量数据可以包含相较于原始系统镜像增加的数据,相较于原始系统镜像删除的数据,在原始系统镜像数据的基础上进行更改的数据等。
步骤C3,将增量数据同步至指定边缘云节点。
其中,指定边缘云节点也就是边缘云节点列表中包含的未更新系统镜像资源的边缘云节点,边缘云节点列表为基于边缘应用模版创建的所有边缘云节 点的列表。在实施中,基于同一个边缘应用模版创建的所有边缘云节点均会记录在一个边缘云节点列表中。
在批量升级弹性云服务器的过程中,只同步增量数据能够在降低数据传输量的同时,提高升级效率。
步骤C4,调用所述指定边缘云节点的云数据中心接口,利用所述增量数据升级所述指定边缘云节点对应的弹性云服务器。
指定边缘云节点对应的弹性云服务器也就是用于向指定边缘云节点提供服务的弹性云服务器。
在实施中,可以直接利用增量数据来对未升级的弹性云服务器进行升级;也可以利用增量数据与未升级的弹性云服务器的系统镜像来得到上述新系统镜像,利用得到的新系统镜像来进行升级。
在实施中,为了提高系统运行的稳定性,可以利用以下步骤D1-D5来对弹性云服务器进行监控,当弹性云服务器出现故障时,能够及时进行故障排查保证系统的稳定运行。
步骤D1,采集用于表征待部署边缘云节点对应的弹性云服务器运行性能的性能数据。
待部署边缘云节点对应的弹性云服务器也就是利用待部署边缘云节点的资源部署的弹性云服务器。
在实施中,可以实时采集各个弹性云服务器的性能数据;也可以按照预定的时间间隔,周期性的采集各个弹性云服务器的性能数据。
上述性能数据可以包含CPU使用率、内存使用率以及服务器带宽数据等。
步骤D2,在性能数据达到预定的告警策略时,确定告警事件。
在实施中,可以设定各个性能数据的告警阈值,当性能数据达到预定的告警阈值之后,则可以确定产生了告警事件。
上述告警事件可以包含服务器故障、CPU过载、内存资源不足等。
步骤D2,在告警事件为故障事件的情况下,利用故障弹性云服务器的配 置,重启或重建弹性云服务器。
在实施中,当弹性云服务器出现故障时,可以重启弹性云服务器,也可以删除该弹性云服务器,然后利用该弹性云服务器的配置来重建一个新的弹性云服务器。
步骤D3,在告警事件为弹性伸事件的情况下,根据伸策略,创建预定比例的弹性云服务器。
伸策略也就是当前弹性云服务器的数量不足以满足用户的需求时增加弹性云服务器数量的策略,比如,当前各个弹性云服务器的CPU使用率超过85%,此时则可以按照预定的比例来增加弹性云服务器的数量。比如,当前弹性云服务器的数量为10个,预定比例为20%,则需要创建2个弹性云服务器。
步骤D4,在告警事件为弹性缩事件的情况下,根据缩策略,删除预定比例的弹性云服务器。
缩策略也就是当前弹性云服务器数量过多而利用率低导致资源浪费时减少弹性云服务器数量的策略。
在实施中,为了提高响应用户请求的速度,可以在接收域名访问请求之后;确定发送域名访问请求的用户的地理位置;将域名访问请求引流至距离地理位置最近的边缘云节点管理的边缘应用。利用距离用户最近的边缘云节点来响应用户的访问请求,以此来提高请求的响应速度。
应用本申请实施例提供的方案,能够通过边缘应用模版来实现对边缘云节点进行统一的部署,降低用户部署工作量以及边缘应用的管理难度;并且可以利用已经完成升级的弹性云服务器的系统镜像得到增量数据,利用增量数据对未升级的弹性云服务器进行批量升级;还能够采集弹性云服务器的性能数据,当弹性云服务器出现故障时,能够及时进行故障排查保证系统的稳定运行;以及在接收域名访问请求之后;利用最近的边缘云节点来响应用户的访问请求,以此来提高请求的响应速度。
