一、horizon 介绍：
理解 horizon
Horizon 为 Openstack 提供一个 WEB 前端的管理界面 (UI 服务 )通过 Horizone 所提供的 DashBoard 服务 , 管理员可以使用通过 WEB UI 对 Openstack 整体云环境进行管理 , 并可直观看到各种操作结果与运行状态。
DashBoard 与其他组件的关系
登陆 Dashboard 界面
启动客户端浏览器，于地址栏输入：
http://Horizone_server_ip/dashboard
二、区域（Region）
1、地理上的概念，可以理解为一个独立的数据中心，每个所定义的区域有自己独立的Endpoint；
2、区域之间是完全隔离的，但多个区域之间共享同一个Keystone和Dashboard(目前Openstack中的Dashboard还不支持多个区域)；
3、除了提供隔离的功能，区域的设计更多侧重地理位置的概念，用户可以选择离自己更新的区域来部署自己的服务,选择不同的区域主要是考虑那个区域更靠近自己，如用户在美国，可以选择离美国更近的区域；
4、区域的概念是由Amazon在AWS中提出,主要是解决容错能力和可靠性；
三、可用性区域（Availability Zone）
1、AZ是在Region范围内的再次切分，例如可以把一个机架上的服务器划分为一个AZ，划分AZ是为了提高容灾能力和提供廉价的隔离服务；
2、AZ主要是通过冗余来解决可用性的问题，在Amazon的声明中，Instance不可用是指用户所有AZ中的同一个Instance都不可达才表明不可用；
3、AZ是用户可见的一个概念，并可选择，是物理隔离的，一个AZ不可用不会影响其他的AZ，用户在创建Instance的时候可以选择创建到那些AZ中；
四、Host Aggreates
一组具有共同属性的节点集合，如以CPU作为区分类型的一个属性，以磁盘（SSD\SAS\SATA）作为区分类型的一个属性，以OS（Windows\Linux）为作区分类型的一个属性；
五、Cell
nova为了增加横向扩展以及分布式、大规模（地理位置级别）部署的能力，同时又不增加数据库和消息中间件的复杂度，引入了cell的概念，并引入了nova-cell服务。
1、主要是用来解决OpenStack的扩展性和规模瓶颈；
2、每个Cell都有自己独立的DB和AMQP，不与其他模块共用DB和AMQP,解决了大规模环境中DB和AMQP的瓶颈问题；
3、Cell实现了树形结构（通过消息路由）和分级调度（过滤算法和权重算法），Cell之间通过RPC通讯，解决了扩展性问题；
六、 dashbord 的配置文件：
