thumb_e2bf3b11df0b872112757f1c2fee6e32

Cloud computing is an expression that perplexes most people. It appears to be a basic enough idea, but different sources provide different definitions, leaving many of us confused as to what it truly is.

What it is:

Cloud computing generally includes Hardware as a Service (HaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). Within those capabilities, companies can offer flexible and scalable options for a number of services, including:

  • Hardware
  • Software
  • Anti-spam
  • Storage servers

Most providers agree that cloud computing always offers three things:

  1. On-demand services with monthly or set pricing.
  2. Flexibility to scale services as necessary.
  3. The consumer simply needs a computer and Internet access to use the service or program.

Although the term can confuse people, cloud computing always uses the power of the Internet to provide products and services to consumers. Check out this InfoWorld article for additional information on the basics of cloud computing.
