CosmosDB – 宇宙级数据库

关于 CosmosDB 更详细的信息,可以查看 Azure Cosmos DB 文档

Azure Cosmos DB 一款宇宙级的数据库,更早在 Microsoft Build 2017 大会上发布。

Azure Cosmos DB 在 2010 年末开始解决 Microsoft 内部大型应用程序开发人员所面临的难题。 由于构建全球分布式应用程序不是 Microsoft 的独家问题,因此我们让该服务以 Azure DocumentDB 的形式供外部所有的 Azure 开发人员使用。 Azure Cosmos DB 是 DocumentDB 发展过程中的下一个重大飞跃,现在我们要让使它能为你所用。 随着 Azure Cosmos DB 的此次发布,DocumentDB 客户连同其数据将自动成为 Azure Cosmos DB 客户。 该转换是无缝进行的,这些客户现在有权访问 Azure Cosmos DB 提供的更广泛的新功能。

现在来到了 Beijing Build Tour 2017,Cosmos DB 同样也来到了中国。

Azure Cosmos DB 无论在全球分布,横向缩放,延迟保证,高可用性,数据模型+API , SLA 都有着其他 关系DB 和 非关系(NoSQL) DB 无法比拟的优势

在 Build Tour Day 2 环节里,有关于 Create a shared CosmosDB to store all data 的使用体验 Build Tour Hack

首先登陆到 Azure 账号 Microsoft Azure

在显示菜单的选项卡里 有 Azure Cosmos DB ,点击之后,会列出我们所有已经创建好了的 Cosmos DB,不过由于 Cosmos DB 距现在发布仅过去一个月左右,因此底层的API 在读取阶段可能还不是很稳定,因此在上图中我们看到了 依然在读取

在 Azure 的所有资源里,我们点击之后会出现类似下图画面 , 这不是因为网络,浏览器等客观原因导致,因为现在的 Cosmos DB 还不足够稳定,毕竟宇宙级,我们的真主会在接下来改善

这里主要为了说明 Cosmos DB 还需要时间去磨练成为一款真正的宇宙级数据库,现在的坑未来会一点点的补上,我们的真主会把光芒洒向大地,让每一个人享受真主带来的快乐

关于如何创建 Cosmos DB ,可按 Task 4.1.1 – Create a shared CosmosDB to store all data 中所提示的在 Azure CLI 里先创建资源住 RESOURCE_GROUP 输入名字(全球唯一)和 部署的 LOCATION ,在中国内陆最好部署到东亚或者东南亚,我把一个按照Task 4.1.1 中的部署到了 EAST US2,另一个放到了 EASTASIA , 最后验证的时候虽然两个位置但都没有相应,还需要给我们的真主一些时间去完善。

最后,Azure Cosmos DB 由 Microsoft 提供,是全球分布式多模型数据库。 只需单击一个按钮,即可通过 Azure Cosmos DB 跨任意数量的 Azure 地理区域灵活且独立地缩放吞吐量和存储。 它通过综合服务级别协议 (SLA) 提供吞吐量、延迟、可用性和一致性保证,这是其他数据库服务无法提供的。
