Creating an Amazon RDS instance by using the AWS CLI
In this lab, I migrate the café Web application to use a fully managed Amazon Relational Database Service (Amazon RDS) database (DB) instance instead of a local database instance. I begin by generating some data on the existing database. This data is migrated to the new Amazon RDS instance. During the migration process, I build the required components, including two private subnets in different Availability Zones, a security group for the database instance, and the RDS DB instance itself. After the database has been migrated, I reconfigure t he café application to use the Amazon RDS instance instead of a local database.
