Performance Measured by the Penny
Cloud computing is a game changer for developers. Not because it requires a new architectural model, that is driven as much by fads and fashion as it is by actual hardware requirements. Nor is it the seemingly endless capacity with near-perfect scalability that the cloud is promising. The game changer is how poorly performing code now has a real price in hard currency.
