There are different types of cloud hosting and one to serve just about every type of business computing need. Beyond the the public and private definitions, you can have a platform as a service (PaaS) model, Software as a Service (SaaS) model or Infrastructure as a Service (IaaS) model. But can you use all three?

I see no reason why not.

A platform as a service model cloud is one where you purchase your computing platform, either as a standalone solution or a solution stack, over the Internet cloud and use a remote service for your basic computing functions. These include your operating system, web server solutions and the like.

A software as a service model is where you use individual software solutions by paying as you use them over the Internet.

Infrastructure as a service is the underlying hardware needed to run your computing operations. This includes servers, desktops, etc.

So, if you were to rent or lease a host of web servers stacked with a custom solution stack that utilized Internet-delivered software solutions for your daily operations then you’d be running your business virtually online. You’d have a cloud-based business in its purity. We are beginning to see some businesses getting their start this way now. In the future, I think this will be a common occurrence.
