Microsoft Azure offers the standard and active geo-replication capabilities for Azure SQL databases. This feature implements a mechanism to provide database redundancy within the same Microsoft Azure region or in different regions (geo-redundancy). Active Geo-Replication asynchronously replicates committed transactions from a database to up to four copies of the database on different servers. When Active Geo-Replication is configured a secondary database is created on the specified server. The original database becomes the primary database. The primary database asynchronously replicates committed transactions to each of the secondary databases. While at any given point, the secondary database might be slightly behind the primary database, the secondary data is guaranteed to always be transactionally consistent with changes committed to the primary database. When you place the secondary database on a server in a different region you add maximum resilience to your application.
