Stacey blogged about the 10 Reasons Enterprise Aren't Ready to Trust the Cloud. Immediately, the conservative enterprise architect in me couldn't have agreed more.

I then picked the brains of my esteemed architect colleagues Nigel and Greg, and it sounds like they're also making the same observation from the community of Enterprise Architects that they engage with in Sydney and in Melbourne, Nigel even wrote me this great summary:

"From the Software plus Service architect councils late last year 1,2,8.9.10 all touched on in various forms in the sessions.  In addition:

Enterprise:

How do we integrate with our internal systems.  Particularly auth and single-sign on.  Perception was that security integration is very difficult

          How do we ensure compliance/privacy requirements are met.

Public Sector:

          Nope.  Never going to cloud-enable citizen data – data custodianship and geo-location issues present major issues (i.e. where are the data centres?)

          National security: somewhat related to the above – never going to convince PS agencies to expose sensitive info to outsiders.

          But.. .internal public cloud configs (i.e. WOG shared services) probably very likely.

          And... hybrid models might be acceptable – i.e. non-sensitive data externalised, sensitive internalised."

Then, I remembered my blog entry a while back "It's the End of the Enterprise as We Know It", and I can't help but think that - cloud computing and services isn't really about just solving our existing enterprise IT challenges, it is not an evolution, but it is the beginning of a revolution, and this time, the revolution will not necessarily be led by the IT department, but by the individual workers/contractors that as a collective act both as the IT service provider as well as the consumer. 'Consumerisation of IT' is only the beginning.

The first start up with the not yet thought of business model, and the not yet thought of user experience, and the not yet thought of relationships enablement will win this brave new world of software plus services.
