Califf: Cloud computing helps to level playing field

If you've checked the business forecast lately, you might have heard predictions about a fluffy phenomenon heading your way. This misty marvel drifts into your browser with the potential to shield your business from the traditional, out-of-the-box software storm it might be caught in, and can drastically reduce cost, allow you to access information wherever an Internet connection can be found, and give your business the agility it needs to compete in today's market.

What is this technological transformation tool you ask? The lighter-than-air computer craze known as "cloud computing."

Over the past few years, cloud computing has accumulated major interest among businesses and Internet technology patrons alike, and recently was chosen by CNN as one of the top Web trends to watch in 2010.

What does cloud computing actually mean?

According to InfoWorld, the "cloud" in cloud computing essentially serves as a representation for the Internet. The computing aspect of the puzzling phrase encompasses different areas that fall into a trio of service categories: Software as a Service, Platform as a Service, and Infrastructure as a Service.

Software as a Service, or SaaS, is an easily deployable software program offered over the Internet. The SaaS model allows a business or user to subscribe to cloud-based software and work within the software while on the cloud. SaaS eliminates the need to consistently update and maintain software, as well as provides rapid deployment and lower-tech support costs.

Platform as a Service, or PaaS, is an extension of the SaaS model, and gives a business the means to customize multiple applications that drive a business. PaaS offers real-time collaboration, easy deployment and customizable user-interfaces.

Last, but certainly not least, is the Infrastructure as a Service model of cloud computing, or IaaS. Pushing software applications aside, IaaS service providers give businesses access to data centers, computer hardware and server hosting capabilities. By taking advantage of the IaaS model, start-up companies, as well as enterprises can keep their overhead costs to a minimum.
