云数据库 SQL Server（TencentDB for SQL Server）具有微软正版授权，可持续为用户提供最新的功能，避免未授权使用软件的风险。具有即开即用、稳定可靠、安全运行、弹性扩缩容等特点，同时也具备高可用架构、数据安全保障和故障秒级恢复功能，让您能专注于应用程序的开发。
说明：
SQL Server 是发行最早的商用数据库产品之一，支持复杂的 SQL 查询，性能优秀，对基于 Windows 平台 .NET 架构的应用程序具有完美的支持，被广泛应用于政府、金融、医疗、零售、教育和游戏等领域。
部署架构
云数据库 SQL Server 支持2种部署架构：
单节点（原基础版）
计算和存储分离，基于高性能云盘，采用单个节点部署。
双节点（原高可用版/集群版）
SQL Server 2008 R2，2012、2014、2016 Enterprise/Standard 版主备双节点架构由一主一镜像（Mirror）的 SQL Server 数据库组成，跨机架/跨可用区部署。
SQLServer 2017、2019、Enterprise/Standard，2022 Enterprise 版主备双节点架构采用 always on 架构，默认跨机架/跨可用区进行一主一备的集群架构部署。
隔离策略
云数据库 SQL Server 单节点（云盘版）及云数据库 SQL Server 双节点（云盘版）基于云服务器 CVM 部署，每个实例独占一台 CVM，独享 CPU、内存、磁盘，不同实例之间完全隔离。
云数据库 SQL Server 双节点（本地盘版）基于本地物理机部署，每台物理机上部署了多个实例，通过隔离策略，保证了不同实例间完全隔离，独享 CPU、内存、磁盘。
此外云数据库 SQL Server 也在账号、地域、可用区、网络等多维度，均作了相应的数据隔离策略。
