Unrestrained build-out of corporate data centers is unsustainable. Cloud computing offers an alternative. Cloud computing sits at the intersection of outsourcing, utility computing and SaaS.
Cloud
computing is a term
that has gone from “new and innovative” to “overused and cliché” faster than
you can blink. Besides that, the definition spans areas ranging
from service-oriented
architecture (SOA), Web services and
software
as a service (SaaS), to hosting
services and outsourcing. Cloud 2.0 can’t be far off.

A recent meeting I had
with executives of
an electric utility company focused on the analogy of electrical generation and
computing services, per Nicholas Carr’s book, The Big Switch:Rewiring the World, from Edison to Google. Part of Carr’s
analysis is to compare the development of other technologies—especially
electricity generation and distribution—to
IT’s development, and to show how IT will move from locally owned and generated
capacity to centralized services. It’s a valid analogy between the
electricity cloud and the data cloud.
When we’ve asked most companies’
management, “Do you use the
cloud?” they generally answer with a quick,
emphatic “no.” But then we find out that the company’s 401K is managed through
a service provider that offers it over the Web, and that
HR and recruiting are done that way, as are a host of other services—all functions
that just a few years ago would never have been delivered on anything but
private company systems.
And so the cloud
grows, even with the occasional burp. I love pundits who predict
that massive service delivery over the Internet is doomed to failure—and point
to a recent outage at Amazon. For them, I have one word: Internet.
You can be a Chicken Little on major tech advances like [Ethernet
inventor] Bob Metcalfe once was: For many years, he warned of the Internet’s
collapse, but he has changed his views. Or you can recognize the
self-improving, self-healing nature of a key trend, such as cloud computing.
But caution is still the watchword in the short term, as the cloud is in its
early stages.
