  • Azure架构(一):云计算基础

    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
