Amazon Elastic Compute Cloud (http://aws.amazon.com/ec2) is a web service that provides resizable compute capacity in the cloud. Amazon EC2 s web service interface allows you to obtain and configure capacity with minimal friction. It provides complete control of your computing resources and lets you run on Amazon s computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as a client s computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. EC2 uses Xen virtualization. Each virtual machine, called an instance, is a virtual private server and can be one of three sizes: small, large, or extra large. Instances are sized based on EC2 Compute Units, which is the equivalent CPU capacity of physical hardware. One EC2 Compute Unit equals a 1.0 1.2GHz 2007 Opteron or 2007 Xeon processor. The available instance sizes are shown in Table 6-1. The service initially offered Sun Microsystems OpenSolaris and Solaris Express Community Edition. In October 2008, EC2 added the Linux and Windows Server 2003 operating systems to its offerings.
