Description:

Amazon Elastic Compute Cloud (Amazon EC2) provides secure and resizable computing capacity in the AWS Cloud. Using Amazon EC2 eliminates the need to invest in hardware upfront, so you can develop and deploy applications faster.

Rationale: 

If you decide that you no longer need an instance, you can terminate it. As soon as the state of an instance changes to shutting down or terminated, we stop charging for that instance. 

Impact:

When you stop the EC2 instance, AWS stops usage charges for the machine But the attached EBS volume (Root) is not deleted and it is still charged in the background, If the EC2 instance is terminated, Then only volume will get automatically deleted, You can changes/do setting in EC2 volume settings delete on Termination checkbox.

Default value :

By default, The EC2 instance is Running
