EC2
EC2 is the short name for Amazon Elastic Compute Cloud. EC2 instances are basically (like) a bare metal VPS you can fire up quickly on demand, in order to quickly build and manage a cloud based hosting infrastructure.
“Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud.”

Powerful.
