It may sound strange, but your organization does not need a strategy for cloud computing. You no more need a strategy for cloud computing than you need a strategy for toothbrushing: as long as your teeth are healthy, who cares if you brush from top to bottom or from left to right, or what brand of toothpaste you use!
So it is with cloud computing: your organization has a business strategy (if not, give me a call). Does that strategy include developing enhanced agility, improved time to market, and increased innovation? If so, then take a deeper look at cloud computing, and build a concrete plan to use cloud computing to fulfill your business strategy.
You don’t need a cloud strategy. You need a business strategy, and a concrete plan to achieve it. If cloud supports that business strategy – then go for it.
