云计算的定义
云计算(英语:cloud computing),是一种基于互联网的计算方式,通过这种方式,共享的软硬件资源和信息可以按需求提供给使用各种计算终端(桌面电脑、笔记本电脑、平板电脑、手机等)的用户。
通过云计算,我们把互联网变为了消费者(顾客)和服务提供商之间的抽象层。
云计算的基本特性
弹性
+ 动态调整服务以适应需求和节约成本
+ 短期策略(产品发布,促销)
伸缩性
+ 垂直伸缩和水平伸缩
池化
+ 计算(中央处理器,内存),存储,网络
+ 随时供应的服务(Services "on tap")
+ 使用多少,就支付多少
供给制
+ 自助服务
+ 基于角色的权限控制(RBAC, Role based access control)
云计算的不同模型
公共云
+ 所有服务存在于互联网
+ 多租户
+ 比如微软云Azure
私有元
+ 所有服务存在于私有网络
混合云
+ 在传统数据中心与云之间建立安全和私有的连接
云交付的不同模型
SaaS
Software-as-a-service 软件作为服务
目标用户:顾客
例如 Office 365 (类似有道云笔记) 和 OneDrive (类似百度网盘)
PaaS
Platform-as-a-service 平台作为服务
目标用户:开发人员
例如 Azure App Service
IaaS
Infrastructure-as-a-service 基础设施作为服务
目标用户:提供管理员
例如 Azure 虚拟机
