Amazon 应用程序恢复控制器 (ARC) 区域切换功能可帮助客户编排多区域应用程序的失效转移流程,以在出现区域故障时实现可控的恢复时间。今天,我们宣布推出三个新的执行块,即 Amazon Aurora Serverless 扩展执行块、Amazon Aurora 预置扩展执行块和 Amazon Neptune 全球数据库失效转移执行块,它们可以自动针对多区域工作负载执行数据库扩展和失效转移。

以主动-被动配置运行 Amazon Aurora Global Database 的客户通常会维护缩减的辅助集群,以最大限度地降低成本。在失效转移期间,他们必须先手动对辅助集群进行大小调整和扩展以处理生产流量,然后再路由请求,从而将恢复时间延长关键的几分钟。作为区域切换计划的一部分,新的 Amazon Aurora Serverless 扩展执行块和 Amazon Aurora 预置扩展执行块可自动对辅助集群进行大小调整和扩展,以便能够在失效转移过程完成后处理生产流量。

运行 Amazon Neptune 全球数据库的客户面临类似的挑战:失效转移功能需根据中断类型编写脚本,或手动决定是执行切换还是分离并升级操作,这一切都需要在活跃事件的压力下完成。新的 Amazon Neptune 全球数据库失效转移执行块可在单个计划中自动执行计划内切换和计划外失效转移方案,从而消除恢复期间的自定义脚本编写工作。

这三个块都支持跨账户编排,从而使单个计划能够协调多个账户和区域的数据库操作。要了解更多信息,请参阅 Amazon Aurora 预配置扩展Amazon Aurora Serverless 扩展Amazon Neptune 全球数据库失效转移的相关文档
