Compute Conceptualized in Terms of Power

Compute can be conceptualized in terms of power - in that it can be defined as the processing power needed to run applications, process data and and do calculations - and in the cloud, this is power "on demand". 

Thus power, and it's availability, is strategically important for cloud providers' expansion. 

Amazon's Elastic Compute Cloud (called EC2 for the double-use of the C) is the epitome of this definition of compute, and represents a powerful compute service from AWS.
