Cloud Computing Defined

When the internet is included in an architecture diagram of a system it is almost always depicted as a cloud. The cloud refers to applications and operating systems running on remote computers accessible locally and usually via the web.

Previously cloud computing was called:

  • Software as a Service (SaaS)
  • Client / Server
  • Time Sharing

Should I have called this mini-post "there is nothing new under the sun?"


  1. Sounds like you'll have some interesting questions to ask Hank Williams at the TechTalk. :-)I don't know if you saw the buzz around Larry Ellison's recent comment along these lines. I tend to agree with you and him but I think there is one new development that is different from the past: the facile scale-up and -down of such systems by Google, Amazon, and now Microsoft with the Azure initiative.

  2. Thanks Bill - Excellent comments by Larry - I hadn't seen that.
