The 7 biggest problem areas of cloud computing

Where users should be wary of cloud computing

Cloud computing is the buzz word of the tech industry right now. But before you leap head first into this concept, we've identified seven problematic areas that you should consider.

There's no doubt that cloud computing is the buzz word of the tech industry at the moment. But wherever there are buzz words, there are a wealth of questions.

When it comes to cloud computing, John Willis, a systems management consultant and author of an IT management and cloud blog, feels the most popular of them all is 'will enterprises embrace this style of computing?'.

"It's not a binary question," he says. "There will be things for the enterprise that will completely make sense and things that won't."

Instead Willis thinks we need to question whether we understand the various offerings and architectures that fit under that umbrella term, the scenarios where one or more of those offerings would work, and the benefits and downsides of using them.

Even cloud users and proponents don't always recognise the down sides and thus don't prepare for what could go wrong, says Dave Methvin, chief technology officer at PC Pitstop, which uses Amazon's S3 cloud-based storage system and Google Apps.

"They're trusting in the cloud too much and don't realise what the implications are," he says.

We've identified the seven most problematic areas of the cloud computing where users should be most wary.

Costs, part I: cloud infrastructure providers

When Brad Jefferson first founded Animoto Productions, a web service that enables people to turn images and music into high-production video, he chose a web-hosting provider for the company's processing needs. Looking out over the horizon, however, Jefferson could see that the provider wouldn't be able to meet anticipated peak processing requirements.

But rather than investing in in-house servers and staff, Jefferson turned to Amazon's Elastic Compute Cloud, a web service known as EC2 that provides resizable computing capacity in the cloud, and RightScale, which provides system management for users of web-based services such as EC2. With EC2, companies pay only for the server capacity they use, and they obtain and configure capacity over the web.

"This is a capital-intensive business," Jefferson said. "We could either go the venture capital route and give away a lot of equity or go to Amazon and pay by the drink."

His decision was validated in April, when usage spiked from 50 EC2 servers to 5,000 in one week. Jefferson says he never could have anticipated such needs. Even if he had, it would have cost millions to build the type of infrastructure that could have handled that spike. And investing in that infrastructure would have been overkill, since that capacity isn't needed all the time, he says.

But paying by the drink might make less economic sense once an application is used at a consistent level, Willis says. In fact, Jefferson says he might consider a hybrid approach when he gets a better sense of Animoto's usage patterns. In-house servers could take care of Animoto's ongoing, persistent requirements, and anything over that could be handled by the cloud.
