Cloud Computing Definitions and Solutions

FAQ: Cloud computing demystified

Michael Dieckmann, CIO at the University of West Florida, thinks otherwise and the two spent Wednesday at the annual Educause conference debating the hype vs. the hope around commercial cloud computing that promises to cut IT costs and provide efficiencies.

Woo's contention isn't so much that the cloud won't emerge as an option, but that IT still has a lot of questions to ask before floating away on its promises.

"Why is the conversation always when, why are we not asking why," she said to a packed Educause session that with a raising of hands showed the audience of higher-ed IT pros are on the fence over cloud computing. "Gartner has cloud computing at the peak of inflated expectations on its hype cycle," she said.

Woo noted recent reports of outages by large providers should grab attention. This week, cloud provider Rackspace reported its third outage since June. Last month, Microsoft reported it lost the data stored by users of T-Mobile's Sidekick service before eventually recovering most of the data. And Google, which provides e-mail services for students, faculty and staff on Dieckmann's campus, has had numerous outages that have frustrated users so much that Google developed a Google Apps Status Dashboard and pumps updates to users via RSS.

"And what about the privacy risks, security risks? Where is that data being stored? Where is research data being stored? How do you handle identity and access management, what happens if the cloud service falls out from under you?" Woo said.

Dieckmann countered that the cloud question is most relevant for commodity services, but the tricky part is that the definition of commodity services is constantly changing.

"To many people e-mail is e-mail," he said. "Storage is becoming more of a commodity. When that service can come externally just are reliably and with the same service levels we can provide why do we need to spend significant resources to run it in-house?"

But on the cost issue, Woo's contention is that most universities don't have a true handle on costs and therefore can't determine if the cloud is saving money.

"Another thing to think about is are we just cost shifting. Are we throwing things over the wall for others to worry about," said Woo, who wonders about the burden put on legal and purchasing departments. "We are not just looking at saving IT costs but costs across the institution."
