Azure Database Migration Services (DMS)

Explanation/Steps

Azure Database Migration Services (DMS) is a fully managed service designed to help you migrate your databases to Azure quickly and securely. It supports migration of various database engines such as SQL Server, Oracle, MySQL, and PostgreSQL to Azure.

The steps to use Azure DMS are as follows:

1. Create an instance of Azure DMS.
2. Configure the source and target connections in Azure DMS.
3. Create and run a migration task that moves the data from the source to the target database.
4. Monitor the progress of the migration task and troubleshoot any issues that may arise.

Examples and Use Cases

Azure DMS is useful for organizations who want to move their on-premises databases to the cloud, migrate databases from one cloud provider to Azure, or perform database consolidations. It can also help simplify the process of upgrading to newer versions of the database engine.

Some examples of use cases for Azure DMS include:

• Migrating an on-premises SQL Server database to Azure SQL Database or Azure SQL Managed Instance.
• Migrating an Oracle database from another cloud provider to Azure.
• Consolidating multiple MySQL databases into a single Azure Database for MySQL instance.

Important Points

• Azure DMS does not modify the source database. It creates a separate copy of the data that is transferred to the target database.
• Azure DMS supports both online and offline migrations. Online migrations can be performed with minimal downtime, while offline migrations require a longer downtime window.
• Azure DMS can be used for both one-time migrations and continuous data replication.
• Azure DMS uses SSL encryption to ensure secure communication between the source and target databases.
