What is EC2?
AWS EC2 is a service that provides a secure and scalable server machine in the cloud. The main advantage of EC2 is that server management is very easy from the AWS Management Console. When you provision an on-premises server, it is not easy to configure security policies, disk management, backup management, and so on. AWS accelerates all this. When you provision EC2, AWS offers different contracts that you need to select and all these types impact the cost.
In order to select the right service, you need to understand what services you are going to use, how many resources you need, and what type of storage you really need. These things are going to help you to reduce the cost and use EC2 efficiently.
