Web Role 的每台虚机运行有 IIS ，用于处理 Web 请求 Worker Role 用于运行后台进程 Cloud Service 是什么？ 支持多层架构的应用容器 由多个 Windows 虚拟机集群构成 集群有两种类型： Web 和 Worker Cloud Service 做什么 进行应用的自动化部署 维护所有虚机的操作系统 / 补丁 /IIS 进行每个集群的故障排除和负载 均衡 进行集中监控、日志收集 普通应用如何发布为 Cloud Service 应用中去除状态 用 VS/Eclipse 进行打包 部署运维
单一虚机不可靠，不建议存储状态信息及数据 每个 Role 建议至少 2 个虚机实例 Role 99.95% 可用性
互联网用户 ❸ 访问 Azure Cloud service Azure Storage 服务 ❷ 上传至 Azure ❻ 性能监控 / 故障 排除 / 配置优化 / 容 量管理 运维人员 ❹ 在 Table 中生成记录， 将源图片存在 Blob 中， 生成一个消息通知 Worker ❺ 读取消息，将 Blob 更新为小图 片，更新 Table

More small instances == more redundancy Some scenarios will benefit from more cores Where moving data >$ parallel overhead E.g. Video processing, Stateful services (DBMS) Don’t just throw big VMs at every problem Scale out architectures have natural parallelism Test various configurations under load
