13 No upfront infrastructure investment No procuring hardware, setup, hosting, power, etc.. On demand access Lease what you need and when you need.. Efficient Resource Allocation Globally shared infrastructure, can always be kept busy by serving users from different time zones/regions... Nice Pricing Based on Usage, QoS, Supply and Demand, Loyalty, Application Acceleration Parallelism for large-scale data analysis, what-if scenarios studies Highly Availability, Scalable, and Energy Efficient Supports Creation of 3 rd Party Services & Seamless offering Builds on infrastructure and follows similar Business model as Cloud

24 Google App Engine is a platform for developing and hosting web applications in Google-managed data centers first released as a beta version in April Google App virtualizes applications across multiple servers and data centers. Google App Engine is free up to a certain level of used resources. Fees are charged for additional storage, bandwidth, or CPU cycles required by the application. [
