What is the function of Azure SQL Data Sync?

The function of Azure SQL Data Sync is to synchronize data between Azure SQL Database and other SQL databases, including on-premises SQL Server databases or other Azure SQL databases. This capability allows for bi-directional data synchronization, which means that changes made to the data in one database can be reflected in another database, ensuring that each location has the most current data.

For applications that require data availability across different locations or where distributed workloads are present, Azure SQL Data Sync provides a robust solution for maintaining consistency and up-to-date information across both Azure and non-Azure environments. This is particularly useful in scenarios where users need access to the same dataset from multiple locations or systems, as it allows for better data sharing and collaboration while reducing the complexity of manual data updates.

The other choices refer to separate functionalities that Azure provides: encrypting data in transit is related to security measures employed across Azure services, monitoring database performance is concerned with analytics and metrics that track database efficiency, and managing security configurations pertains to access control and permissions within Azure environments. Each of these serves a different purpose and does not specifically address the synchronization capabilities that Azure SQL Data Sync offers.
