Cloud is still hype and I recommend everybody to take a look in things like node.js

Off course it demands depends first on the business model and its more appealing for scenarios like low server side processing with a large number of users.

The average web bandwidth is a major factor. If your users don't got a good bandwidth they ill not consume a lot of web services lowering the demand for clouds.

Its a great solution for all those small applications we are doing to connect people and if you are developing web applications chances are you ill build something in the cloud in next years.

A new (MS SQL) forum solution for example 😀
