While there is talk that cloud computing is a rebranding of what already exists, we also see many comments about cloud computing representing a major paradigm shift. We see articles talking about vertical, horizontal public, private, and hybrid clouds, with each representing an approach that matches cloud computing concepts to specific market requirements. What appears to be emerging is a taxonomy of cloud computing that includes: Infrastructure as a Service (IaaS); Platform as a Service (PaaS); and Software as a Service (SaaS).

1) Possible downtime. Cloud computing makes your small business dependent on the reliability of your internet  connection. When it's offline, you're offline. If your internet service suffers from frequent outages or slow speeds cloud computing may not be suitable for your business. And even the most reliable cloud computing service providers suffer server outages now and again. 

2) Security issues. How safe is your data? Cloud computing means internet computinging. So you should not be using cloud computing applications that involve using or storing data that you are not comfortable having on the Internet

Leaving aside revelations about the NSA, switching to the cloud can actually improve security for a small business, says Michael Redding, managing director of Accenture Technology Labs.

"Because large cloud computing companies have more resources, he says, they are often able to offer levels of security an average small business may not be able to afford implementing on its own servers" (Outsource IT Headaches to the Cloud (The Globe and Mail).

3) Cost. At first glance, a cloud computing application may appear to be a lot cheaper than a particular software solution installed and run in-house, but you need to be sure you're comparing apples and apples. Does the cloud application have all the features that the software does and if not, are the missing features important to you?

You also need to be sure you are doing a total cost comparison.While many cloud computer vendors present themselves as utility-based providers, claiming that you're only charged for what you use, Gartner says that this isn't true; in most cases, a company must commit to a predetermined contract independent of actual use. To be sure you're saving money, you have to look closely at the pricing plans and details for each application.

In the same article, Gartner also points out that the cost savings of cloud computing primarily occur when a business first starts using it. SaaS (Software as a Service) applications, Gartner says, will have lower total cost of ownership for the first two years because SaaS applications do not require large capital investment for licenses or support infrastructure. After that, the on-premises option can become the cost-savings winner from an accounting perspective as the capital assets involved depreciate.

Cloud computing costs are constantly changing, so check current pricing.
