Cloud computing: The telcos' game to lose

You're probably sick of hearing about cloud computing. I can't say I blame you. The buzz seems to be nearly deafening these days. And the most annoying part is that for those of us old enough to remember, it's "back to the future" all over again.

True old-timers can recall the days when "cloud computing" meant a mainframe and associated terminals. And younger veterans of the dot-com years still remember application service providers.  I won't say which I am -- but I have to agree that the current incarnation looks eerily familiar.

However, things really are different these days. Here's why: Cloud computing offers an unprecedented ability for users to specify exactly what they want, in two ways.

First, they can define exactly they want to buy. Software-as-a-service offers network-based delivery of a specific application (Salesforce.com being one of the best-known examples) with the underlying software and hardware hidden from the user. Platform-as-a-service delivers a "compute platform," typically an operating system plus a range of software tools. And infrastructure-as-a-service delivers storage and compute cycles on demand.

Second, users can control exactly how much they want to consume, and when. Providers typically offer services (whether software, platform or infrastructure) based on a virtualized architecture, which lets users auto-provision and quickly scale up (or down) to address demand spikes.

For these reasons, cloud computing is more than just hype. In fact, although fewer than 2% of my clients say they're using it this year, nearly 20% say they're looking into cloud-based services.

So where do telcos come in? Basically, they're beautifully positioned to capitalize on the drive towards cloud computing -- particularly infrastructure-as-a-service -- if they don't screw it up.
