But today, Google is pushing the App Engine to be a more mature and business-ready platform. The company announced today that users can now pay to remove the quota on their usage of the App Engine. On the free side of the fence, this will, however take a bite out of performance: users of the free form of App Engine will see their resource pool shrink over the next 90 days, giving professionals more to work with on the backend. All the details are on the App Engine page. Now the real question is how will Google App Engine stack up against Amazon Web Services in the real business world."
