How convenient would this be?
- choose the desired service
- pay
- take and use
By using PaaS, you only need to take care of the application and data. Without cloud, you have to take care other such as networking, storage server, operating system, middleware and more.
Using RDS you just have to take care of the cloud database service-related tasks, such as security task, manage database and account. If you need performance, you always can perform vertical and horizontal scaling with a click.
