“The interesting thing about cloud
                           computing is that we’ve redefined
What is Cloud Computing?   cloud computing to include
                           everything that we already do.
                           […] The computer industry is the
                           only industry that is more fashion-
                           driven than women’s fashion.
                           Maybe I’m an idiot, but I have no
                           idea what anyone is talking
                           about. What is it? It’s complete
                           gibberish. It’s insane. When is
                           this idiocy going to stop?

• “
• Cloud computing is simply a buzzword used
  to repackage grid computing and utility
  computing, both of which have existed for
  decades.”

                    definition of Cloud Computing
(Good Luck) Defining Cloud Computing
  •   Software-as-a-Service
       – “My customer resource management
         (CRM) system is out on the Internet!”
  •   Grids vs. Clouds
       – Shared Virtual Resources
       – Batch Jobs vs. Online Applications
       – Different Approaches to State
         Management
  •   Network Diagrams
       – A service is “on a cloud somewhere”
  •   Virtualization Platforms & APIs
       – Hardware can be manipulated with
          software

  provider of servers, storage, and bandwidth)

• Cloud = Scale
  (tens of thousands of server computers)

• Cloud = Flexible and Efficiency

[…] The computer industry is the only industry that is more fashion- driven than women’s fashion. Maybe I’m an idiot, but I have no idea what anyone is talking about. What is it? It’s complete gibberish. It’s insane. When is this idiocy going to stop? Larry Ellison during Oracle’s Analyst Day

  • 9. (Good Luck) Defining Cloud Computing • Software-as-a-Service – “My customer resource management (CRM) system is out on the Internet!” • Grids vs. Clouds – Shared Virtual Resources – Batch Jobs vs. Online Applications – Different Approaches to State Management • Network Diagrams – A service is “on a cloud somewhere” • Virtualization Platforms & APIs – Hardware can be manipulated with software
