What is an EC2?
EC2 refers to Elastic Compute Cloud which is a virtual computing service offered by amazon web services (AWS). EC2s behave exactly like our normal computers except that they are cloud based and they could be accessed from anywhere.
Like any computer, EC2s come with specs, RAM size, storage size, processor type, speed etc. There are different type of EC2 instances that AWS provides, and you can chose base on your needs. AWS provides the following instance type:
General Purpose

Memory Optimised
Accelerated Computing
With each instance type having its purpose.
