使用 Amazon DMS 复制实例
当你创建Amazon DMS复制实例,Amazon DMS在基于亚马逊 VPC 服务的虚拟私有云 (VPC) 中的 Amazon EC2 实例上创建它。您可以使用此复制实例执行数据库迁移。通过使用复制实例,您可以通过多可用区部署获得高可用性和故障转移支持,前提是您选择多可用区选项。
在多可用区部署中,Amazon DMS 自动在不同可用区中预置和维护复制实例的同步备用副本。主复制实例可以跨可用区同步复制到备用副本。此方法提供数据冗余,消除 I/O 冻结,并将延迟峰值降至最小。

Amazon DMS 使用复制实例连接到源数据存储,读取源数据并设置数据格式以供目标数据存储使用。复制实例还会将数据加载到目标数据存储中。大部分这种处理发生在内存中。但是,大型事务可能需要部分缓冲到磁盘上。缓存事务和日志文件也会写入磁盘。
你可以创建一个Amazon DMS以下为复制实例Amazon区域。
