How to Avoid the Hidden Costs of Cloud Computing

We all know the conventional wisdom about cloud computing: it's cheap, fast and easy. But is it really that much cheaper? Or is it simply optics that make it appear cheaper?

Optics can absolutely change your perception of the cost of something. Just think about your morning jolt of coffee. $3.50 for a no-foam, half-caf, sugar-free vanilla latte doesn't seem that expensive. It's a small daily expense when viewed by the drink. It appears even cheaper if you pay for it with a loyalty card where you don't even have to fork over the dough and the vanilla shot is free. But what if you bought coffee like IT buys technology? You would pay for it on an annual basis. That $3.50 latte would now be about $900/year. For coffee? How many of you would go for that deal? That's optics and it plays right into the marketing hands of the public cloud services your business is consuming today.

But optics aside, is that $99/month per user SaaS application just another $20,000 per year enterprise application? Is that $0.25 per hour virtual machine just another $85 per year hosted VM? No, it's not the same. Because the pricing models are not just optics but an indication of the buying pattern that is possible. If you buy it the same way you do traditional IT, then yes, the math says, there's little difference here. The key to cloud economics is to not buy the cloud service the same way you do traditional IT. The key to taking advantage is to not statically and rotely consume the cloud. Instead, consume only what you need when you need it — and be diligent about turning off when you aren't.
