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.
