In the Enterprise/Web 2.0 view of the world, this is all behind-the-scenes stuff that the IT guys worry about. Enterprise/Web 2.0 proponents talk about building communities, collaboration, and moving information more openly and efficiently across networks.

If that’s your definition, then I wouldn’t put Clouds there. I’m not sure if they encourage collaboration.

SHAMELSS SELF-PROMOTION WARNING:
However, if you define Enterprise 2.0 a more broadly (as I do in my forthcoming book), the clouds qualify. I look at “E2″ as a term to encompass technologies such as SaaS, BI, MDM, SOA, clouds, and others that, while technically around at some point, were by and large not adopted by many organizations–at least not well.

In short, it’s all about how you define the term.

Could computing is primarily about cost reduction. It makes efficient use of resources by allowing companies to scale computing systems according to demand. Ideally, cloud computing means that you always have the right amount of infrastructure support for your business applications.

Enterprise 2.0 is about productivity gains. It’s about using new communication and collaboration technologies to enable people to work together more effectively.

Trying to combine both efforts into a single IT initiative risks confusion.
