But, the advent of the Cloud platform has turned the tide completely in favor of online services which can reduce the expenditure on onsite resources. One such platform is Amazon Relational Database System which is a web-based database application. It is a cost-effective and scalable platform for businesses.

AWS Database Migration Service
AWS Database Migration Service is a dedicated service for swift and easy database migration. The source database of the Microsoft SQL Server remains operational during the migration, and it allows you to work as usual. It does not require any prerequisites to start the migration; it initiates the migration within some clicks. It follows two approaches for the migration –
- Homogeneous Database Migration
As the name suggests, homogenous data migration is suitable for such databases which are either same or compatible with each other like MySQL to RDS, Microsoft SQL Server to Amazon RDS, MySQL to Amazon Aurora, or Oracle to Amazon RDS. The homogenous databases has a similar database schema, database types, and database codes. That’s why the migration procedure is more straightforward for it. You can start the migration by connecting with the source SQL Server to and the target database.
- Heterogeneous Database Migration
In the Heterogeneous Database migration, the source and target database have a different kinds of database schema. These kinds of migrations are Oracle to Postgre SQL, Microsoft SQL Server to MySQL, Oracle to Amazon Aurora. Before starting the migration, you need to transform the schema structure, data types, and database codes. There is a unique AWS Schema Conversion Tool which is used to convert the destination database schema as per the source database schema.
