Elastic Compute Cloud (EC2)
◦ Provides virtual machine instances called Amazon Machine Instances
◦ Ability to create AMI’s on the fly according to demand

Simple Queue Service (SQS)
◦ Provides reliable messaging between any applications using AWS

Amazon EBS

Amazon Cloud Front
◦ Think of this as a simple web server for static content

Ability to increase or decrease capacity
within minutes
Ability to commission one, hundreds, or
even thousands of server instances
simultaneously
A web service API to control the scaling
of instances depending on your needs
A “pay only for what you use” pricing
model
