What is an Amazon EC2 Instance?

Amazon Elastic Compute Cloud (Amazon EC2) provides scalable

computing capacity in the Amazon Web Services (AWS) cloud.

Using Amazon EC2 eliminates your need to invest in hardware up

front, so you can develop and deploy applications faster.

You can use Amazon EC2 to launch as many or as few virtual

servers as you need, configure security and networking, and

manage storage. Amazon EC2 enables you to scale up or

down to handle changes in requirements or spikes in popularity,

reducing your need to forecast traffic.
