Amazon EC2 (Elastic Compute Cloud) is an AWS computing service that provides virtual servers in the cloud. It allows you to create, run, and manage applications without buying physical hardware.
With Amazon EC2, you can choose the operating system, instance type, storage, and networking based on your application needs. EC2 instances can be started, stopped, resized, or terminated at any time.
In simple words, Amazon EC2 is a virtual computer in AWS that you use to host websites, run applications, and perform computing tasks.
