在DB Mirror的架構中，雖然SQL Server是裝在兩台，但是授權只要一台！
如果換成AlwaysOn之後，反而變成要買兩台？

AlwaysOn 兩台都在服務因此需要購買兩台的license
文件之中第11頁有提到
SQL Server software can be configured so that if one server fails, its processing will be picked up, recovered
This figure shows an example of licensing active and passive secondary SQL Server 2012 databases with a core factor of 1
and continued by another server. All editions of SQL Server 2012 provide basic high availability features
including backup log shipping, database mirroring and two-node failover clustering. Advanced (AlwaysOn)
high availability features in SQL Server 2012 Enterprise Edition include enhanced support for multiple, active
(readable) secondary servers and support for multi-site failover clustering.james
