AWS VS Azure , which one is preferable for SQL Server 2012 standard version?
With Azure SQL Database you have the option of Geo-Replication. Active geo-replication enables you to configure up to four readable secondary databases in the same or different data center locations (regions). Secondary databases are available for querying and for failover if there is a data center outage or the inability to connect to the primary database. The failover must be initiated manually by the application of the user. After failover, the new primary has a different connection end point. You can learn more about this Azure SQL Database feature here.
