As CSA chapter chair, I has been asked many times about what is cloud computing?

3M AVS is one excellent example of cloud, with the following characteristics

• usage-based, the user only pay on each image analysed
• deliver via Internet (remotely), the image is processed remotely
• access to expertise, ordinary users and SME could access to 3M research results

Take a look at 3M Visual Attention Service and this application runs on cloud infrastructure !
