Scoring in the Amazon Cloud
ADAPA on the Amazon Cloud uses the Amazon Elastic Compute Cloud (Amazon EC2) infrastructure and so ADAPA can be launched on different instance types (or virtual machines), availability zones, and regions as provided by Amazon EC2.
Availability Zones are distinct locations that are engineered to be insulated from failures in other Availability Zones. Regions consist of one or more Availability Zones, are geographically dispersed, and are located in separate geographic areas or countries. By launching an instance in a region closer to you and your customers, you insure shorter latency times.

US East Region (North Virginia)
Asia-Pacific (Singapore, Sydney and Tokyo)
South America (Sao Paulo)
The more processing power or memory an instance has to offer, the more it costs. Currently, you can choose to launch ADAPA on the Amazon Cloud in 3 different types of virtual machines. You are only charged if an instance is running. Prices per hour (or partial hour) start at $0.99. Once you sign-up for ADAPA on the Amazon Cloud, you are able to launch ADAPA on different instances and regions concurrently by using the Amazon AWS Marketplace.

In the Amazon Cloud, the amount of CPU that is allocated to a particular instance is expressed in terms of EC2 Compute Units. Several benchmarks and tests are used to manage the consistency and predictability of the performance of an EC2 Compute Unit. One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.
