RDS SQL Server异地容灾最佳实践

本视频演示如何为RDS SQL Server主实例创建异地灾备实例，帮助您快速部署异地容灾架构。通过异地灾备实例，您可以在主实例发生故障或所在区域不可用时，快速提升灾备实例为主实例，从而保障业务连续性、实现数据库的高可用性和灾难恢复能力。此外，异地灾备实例支持只读访问，能够分担主实例的查询压力，满足多地域部署和业务应用就近访问的需求。

提升灾备实例为主实例

灾难恢复场景下，如果主实例所在区域不可用，或其他情况导致主实例和灾备实例之间存在数据延迟、不满足切换条件，您可以自行评估业务情况，通过提升灾备实例为主实例来快速恢复业务读写。提升后，灾备实例与主实例之间的数据同步链路将中断，原灾备实例和主实例都将作为独立实例运行。
