The _____ system mechanism provides tools and user-interfaces for external cloud resource administrators to configure and administer cloud-based IT resources.
A
SLA management
B
remote administration
C
resource management
D
billing management
答案:B

9.1 远程管理系统(remote administration system) 远程管理系统机制向外部云资源管理者提供工具和用户界面来配置并管理基于云的IT资源。

远程管理系统能够建立一个入口以便访问各种底层系统的控制与管理功能,这些功能包括了本章介绍的资源管理、SLA管理、计费管理。

A remote administration system can establish a portal for access to
administration and management features of various underlying systems.

远程管理系统主要创建两种类型的入口(the remote administration system created two
primary types of portals— Usage and Administration Portal and
Self-Service Portal. ):

(1)使用与管理入口(Usage And Administration Portal)

一种通用入口,集中管理不同的基于云的IT资源,并提供IT资源使用报告。

这个入口是许多云技术架构的组成部分。

(2)自助服务入口(Self-Service Portal)

该入口本质上是一个购买门户,它允许云用户搜索云提供者提供的最新云服务和IT资源(通常是租赁的)列表。

云用户通常能够执行的任务:

(1)配置与建立云服务

(2)为按需云服务提供和释放IT资源。

(3)监控云服务的状态、使用和性能

(4)监控QoS和SLA的实行

(5)管理租赁成本与使用费用

(6)管理用户账号、安全凭证、授权和访问控制。

(7)跟踪对租赁服务内部与外部的访问

(8)规划与评估IT资源供给

(9)容量规划

9.2资源管理系统(resource management system) 资源管理系统机制帮助协调IT资源,以便响应云用户和云提供者执行的管理操作。

此系统的核心是虚拟基础设施管理器(VIM)(Core to the resource management system mechanism
is the virtual infrastructure manager (VIM)
),它用于协调服务器硬件,这样就可以从最合适的底层物理服务器创建虚拟服务器实例。

通过资源管理系统自动化实现的任务包括:

(1)管理用来创建预构建实例的虚拟IT资源模板,如虚拟服务器映像。

(2)在可用的物理基础设施中分配和释放虚拟IT资源,以响应虚拟IT资源实例的开始、暂停、继续和终止。

(3)在有其他机制参与的条件下,协调IT资源,如:资源复制,负载均衡和故障转移系统。

(4)在云服务实例的生命周期内,强制执行使用策略与安全规定。

(5)监控IT资源的操作条件。

资源管理系统通常发布API,以便云提供者建立远程管理系统入口。该入口可以定制为通过使用与管理入口,向代表云用户组织的外部云资源管理者选择性提供资源管理控制。

9.3 SLA管理系统(SLA management system) SLA管理系统机制代表的是一系列商品化的可用云管理产品,这些产品提供的功能包括:SLA数据的管理、收集、存储、报告以及运行时通知。

部署SLA管理系统时,常常会包含一个库,用于存储和检索被收集的基于预定义指标和报告参数的SLA数据。收集SLA数据还需要依靠一个或多个SLA监控机制,之后,根据活跃的云服务,使用与管理入口可以近实时地利用这些数据来提供持续的反馈。使得个人云服务监控的指标与云提供合同中的SLA条款一致。

9.4 计费管理系统(billing management system) 计费管理系统机制专门用于收集和处理使用数据,它涉及云提供者的结算和云用户的计费。

The billing management system relies on pay-per-use monitors to gather
runtime usage data

计费管理系统依靠按需使用付费监控器来收集运行时使用的数据。这些数据存储在系统组件的一个库中,然后为了计费、报告和开发票等目的,从库中提取数据。

使用后支付。

使用前支付类型分为两种:

(1)预定义限制

(2)无限制使用
