Why Enterprises Buy Cloud Computing Services

Why are enterprises interested in any sort of cloud computing service? For the same reasons they are interested in just about any other computing or communications tool: they think it will reduce costs and create more value in the information technology investment.

Of course, enterprises don't buy "cloud computing." They buy tools that help them run their businesses.

Email might be an area ripe for a cloud shift, in that regard. It is a necessary function, but a function without compelling strategic advantage.

Typically, necessary but non-strategic functions are the sorts of processes one can think about outsourcing. And it is getting more burdensome to manage email processes, with growing  enterprise regulatory requirements relating to storage of email. The other issue is that email, like most other applications these days, "suffers" from bandwidth creep.

Over time, people are appending larger attachments, for example. Cisco's WebEx Mail service, for example, has full Outlook support. That means users will see no changes, nor will IT departments need to deal with massive training issues and client software updates.

But it isn't the "cloud" that makes the the change interesting. It is the savings in time, labor, money and functionality that will be key. "Cloud computing" as such will be interesting for some enterprises that want to shift capex into opex, that are growing very fast or that are primarily Web based.

For others it might be a way to offload server or computing center chores. But I suspect most users will find they prefer to use a cloud-based application or service because of the value the specific applications represent, because of the consumption or pricing model.
