什么是 Windows Azure?

在云端的操作系统

降低 互联网应用可扩展的复杂性

以可用性和可扩展性作为设计目标

只运行在微软的数据中心

6

什么是 Windows Azure?在云端的操作系统

跨多台服务器的抽象硬件分布式伸缩 , 高可用的存储部署、监视和维护自动化服务管理 , 负载均衡 , DNS编程环境互操作性仅为有效计算设计

存储 Blobs, Tables, Queues为云而设计

3 份复制确保一致性

通过 REST API 直接访问 Internet不参与计算通过单独的存储帐户访问SDK 提供简单的存储客户端

19

Blobs

Blobs 存储在容器中每个帐户 1 个或更多的容器

Scoping is at container level…/Container/blobpath

BlobsCapacity 50GBMetadata, accessed independently

name/value pairs (8kb total)

私有或公开文件系统使用 Blobs

23

Tables

实体和属性（行 & 列）Tables scoped by account 设计为 billions+ 级别使用分区实现可扩展

Partition key & row key高效查询不限制分区数量

使用 ADO.NET Data Services

设计考虑可用性和可扩展式设计的关键点存储不是关系型数据库无状态

Stateless front ends, store state in storage使用队列进行解耦Instrument your applicationOnce you are on - stay on思考补丁 & 升级
