What is Amazon DMS

Every day, more and more companies are moving towards cloud computing, with Amazon Web Services (AWS) undoubtedly being the biggest player. Having all the possible AWS services available at your fingertips is great, but you still need to migrate your existing infrastructure and data into the (AWS) cloud. At re:Invent 2015, Amazon announced “AWS Database Migration Service”, aiming to make the process of moving data into databases on AWS a lot easier.

AWS DMS supports most open-source and commercial databases such as PostgreSQL, MySQL, MariaDB, Oracle, Microsoft SQL Server, and of course their own Aurora, Redshift, DynamoDB and S3 services.

DMS regularly gets updated with new features and supported engines.
