Creating an application database using RDS

The sample todobackend application includes a MySQL database that is used to persist todo items that are created through the application API. When you first set up and ran the sample application back in Chapter 1, you used a Docker container to provide the application database, however, in production-grade environments, it is generally considered best practice to run databases, and other services that provide persistent storage, on dedicated machines optimized specifically for database and data access operations. One such service in AWS is the relational database services (RDS), which provides dedicated managed instances optimized for providing popular relational database engines, including MySQL, Postgres, SQL Server, and Oracle.
