实例规格
RDS for SQL Server实例支持的数据库版本请参见数据库引擎和版本。
RDS for SQL Server实例规格的CPU架构为X86架构，详见表1。支持的规格列表请参见表2和表3。
|
规格 |
说明 |
适用场景 |
|---|---|---|
|
通用型 |
与同一物理机上的其他通用型规格实例共享CPU资源，通过资源复用换取CPU使用率最大化，性价比较高，适用于对性能稳定性要求较低的应用场景。 |
侧重对成本、性价比要求较高的场景。 |
|
独享型 |
完全独享的CPU和内存，性能长期稳定，不会因为物理机上其它实例的行为而受到影响，适用于对性能稳定性要求较高的应用场景。 |
电商、游戏、金融、政企等核心数据库场景。 |
|
惠选型 |
完全独享的CPU和内存，性能长期稳定，不会因为物理机上其它实例的行为而受到影响，适用于对性能稳定性要求较高的应用场景，与独享型相比在价格方面有一定优惠。 |
电商、游戏、金融、政企等核心数据库场景。 如需购买该规格的实例，请提交工单申请。 |
|
共享型 |
独享被分配的内存，与同一物理机上的其他共享型规格实例共享CPU资源。实例有资源争抢风险。 通过资源复用换取CPU使用率最大化，性价比较高。适用于对性能稳定性要求较低的应用场景。 |
目前仅RDS for SQL Server企业版实例支持共享型规格。 支持的区域：上海一、北京四、乌兰察布一、广州、贵阳一 |

a：RDS for SQL Server实例规格定义的内存包括RDS相关管理服务、数据库服务和底层操作系统占用的内存（如BIOS预留内存、内核和Hypervisor运行内存等）。因此，您查看的可用内存会小于实例规格定义的内存。RDS for SQL Server云盘实例基于ECS搭建，各实例采用的ECS实例规格族可能不同，因此性能会有所差异。
数据库实例规格请以实际环境为准。
