Should you move (or launch) your startup into the cloud? Proponents of cloud computing will likely tell you unequivocally "yes." more entrenched IT forces may respond with an unequivocal "no."

Cloud Computing: Quick Definitions

There are three main categories of cloud computing.

Software as a Service (Saas): the most common use of the cloud, SaaS is also known as "software on demand." rather than downloading and running software locally, customers access the software via the Internet.

Platform as a Service (PaaS): As the name suggests, PaaS involves the delivery of a computer platform, with the ability to develop and deploy websites and services via the Internet.

Infrastructure as a service (IaaS): IaaS provides all the basic computing building blocks, but is the most complex choice. This does allow you build your platform and your services.
