Now that the Software as a Service (SaaS) delivery model has proved itself at the departmental level, some CIOs are ready to go with SaaS for some more complex enterprise applications. And vendors are there to meet them, with services such as integration with legacy systems, custom development and even business process improvement.

As applications like enterprise resource planning (ERP) become available via SaaS, customers' complex business rules often require customization from the standard SaaS offering, said Liz Herbert, an analyst at Forrester Research Inc. in Cambridge, Mass.

SaaS contract negotiations are taking on new dimensions as vendors introduce utility-like pricing options and try to lock customers into longer contracts. And by building in support for more customizable applications and creating ecosystems of technology partners for related applications, they are also making it more difficult to switch from one provider to another.

"A lot of SaaS offerings were pretty basic and you had an easier time switching from one to another [until recently]," Forrester's Herbert said. "Vendors are now trying to make it more difficult to switch by making their applications much more customizable." They are also trying to tempt customers into signing longer contracts, in some cases up to five years, by offering steep volume licensing discounts, she said.

There are reasons aplenty to stick your head into cloud computing, says Forrester analyst James Staten. IT can't keep up with the demands of the business. The best Web services companies have maxed out their data centers for efficiency, and those babies can handle almost anything you throw at them. You pay by the drink. You are free of long-term contracts. Most cloud vendors let you come and go as you please, Staten said. And all you need to do is log in.

But that doesn't mean cloud computing is enterprise-ready. For your entertainment: 12 reasons, courtesy of Staten and his team, why cloud computing is -- or isn't -- coming to an enterprise near you.
