高可用性，是很多数据库工程师/架构师最重视的系统架构环节。在AWS上，Multi-AZ是RDS很重要的一个HA方案。但是启用Multi-AZ，对系统性能是否有影响，性能牺牲多少，是很多用户关系的点。今天，我就针对Multi-AZ的性能进行测试。
1. 环境准备，创建m4.xlarge（4CPU 16G）的EC2，和RDS Mysql在同一个AZ，这样能减少网络因素的影响
创建一个db.m4.xlarge（4CPU 16G）的RDS Mysql
2. 基于RDS AMI2安装sysbench的方法3. sysbench数据生成，在sbtest库下生成sbtest表，共100W记录。sysbench的更多用法，请参考另一篇blog，https://blog.51cto.com/hsbxxl/2068181
4. EC2机器需要安装mysql client，用于准备连接数据库使用RHEL7系列mysql5.7的下载地址：5. 连接数据库6. 创建测试数据库：7. 插入数据，创建测试表20个每个表100万行数据。查询整个mysql数据库大小，准备了50G的数据，准备测试实际上我是通过多次执行sysbench，创建多个库之后，才把数据堆积到50G,但是测试过程中，只有4.2G8. 准备测试，分别测试并发数为30，50，100，200，800，1000的情况9. 测试结果如下Single-AZMulti-AZ30
