Impossible Expectations
Tomorrows business leaders will expect I.T. to function like an App Store. They are already getting useful services "from the cloud." I've personally seen a handful of businesses start the move to Salesforce.com without telling the I.T. department or including them in the evaluation!
My nerdy brothers and sisters, we can rail against this change all day long, we can dislike it, we can be vocal about it ... but it will not delay things one single minute. For years, I.T. security, network, storage, etc. have said "no" to various business initiatives (usually for good reason), but now, you will have to weigh the option of the business "outsourcing" that service from the cloud no matter how hair-brained it may sound.
