Using the AWS DMS to Migrate Data to an Aurora Database

One of the most important aspects of any migration of data to the cloud is cost optimization. Luckily, AWS has made this relatively simple thanks to the Database Migration Service. In this hands-on lab, we are going to use the Database Migrations Service (DMS) to migrate a MySQL database from an EC2 server to an RDS Aurora MySQL database.
