  2. 2. What is it?
    Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
    -- Mell & Grance, 2009
  3. 3. What is it?
    [Cloud computing is] the delivery of scalable IT resources over the Internet, as opposed to hosting and operating those resources locally, such as on a college or university network.
    -- EDUCAUSE, 2009
  4. 4. What is it?
    Basic characteristics:
    • Users interact with resources remotely with few to no intermediaries

    • 6. Resource use is flexible and scalable, and priced accordingly
  5. What is it not?
