Too Long; Didn't Read
I have been using <a href="https://hackernoon.com/tagged/aws" target="_blank">AWS</a>(Amazon Web Services) services for more than 5 years, EC2 has been the service I have used the most in Amazon Web Services. I have developed many web based applications and services running on EC2 so far. Since EC2 comes with its own configuration, developers miss out to use RDS. What I mean, let’s say you want a windows server including IIS, SQL Server. You probably open EC2 interface, click “Launch Instance” button and select one image(AMI), then you use the server sometime as a standalone <a href="https://hackernoon.com/tagged/database" target="_blank">database</a> or as both a web service and a database. That is the main reason why it isn’t so popular.
