How is your -aaS unique?

When I saw a company advertising Infrastructure as a Platform (crossing out IaaS and PaaS in the process) at the Cloud Computing Expo (http://cloudcomputingexpo.com/) earlier this month, it occurred to me that -aaS has become well accepted (and crowded) that cloud providers, builders, and integrators are looking to differentiate themselves in less familiar ways to stand out in front of customers.

Speaking with vendors at the expo, it appears many try to differentiate with price, security, scaling, and integration: more hosting services are competing on rates and promotions, cloud security, provisioning, monitoring are getting better defined, FUD on scalability, uptime, and performance are all around, and integration (blurring) of public and private clouds are discussed/debated as the current and future trends.

Though the world is becoming flatter with the internet, only a few speakers made mentions of cloud computing outside of north America. In October Beijing unveiled a five-year plan for cloud computing with a market estimated at $30B: a translation of this page http://www.hdcatv.com/hdyzk/html/2010-10/14/content_23662.htm?div=-1 can give a better idea of what this is. The market shift is taking place quickly, and this will be a huge public cloud as it takes shape. Some leaders are developing capabilities in China: EMC already built 13 sites and grew to 1000 people working on cloud in different cities there, while most people don't see the cloud computing being relevant there in the next 2-3 years.

Are you a -aaS innovator? How are you differentiating from the "imitators"?
