Drivers for the data replication solution pattern include:

• We need a common persistent store to ensure a consistent view of the system across all application servers (whether active-redundant or load-balanced).
• High availability architectures depend on application data and code. Hence it is essential to have high availability for data and code. One of the popular strategies is site replication which is also used to handle DR.
• The database objects, schema updates, and data will be replicated to all mirror sites by the synchronization job. For optimization, only the incremental/differential data will be chosen for synchronization.
