我需要确保数据库的可用性很高。使用 SQL Azure 并不能说明这一点。
有没有办法在SQL Azure下运行多服务器(如果一台服务器出现故障，一台服务器将接管？)，上面是否有相当于增加数据库服务器上的内存以加速数据库处理的方法？
最佳答案
阅读 Intro the Azure SQL 上的高可用性然后阅读Business Continuity in Windows Azure SQL Database 。总结一下:
Data durability and fault tolerance is enhanced by maintaining multiple copies of all data in different physical nodes located across fully independent physical sub-systems such as server racks and network routers. At any one time, Windows Azure SQL Database keeps three replicas of data running—one primary replica and two secondary replicas.
