Survey Shows Businesses Interested, But Still Conflicted, About The Cloud: Page 2 of 2

The survey broke down the level of cloud adoption by service type, also based on a one-to-five scale. Use of a public software-as-a-service (SaaS) model, such as that from Salesforce.com, ranked highest, with a 3.5; the public infrastructure-as-a-service (IaaS)  model, such as Amazon Web Services, ranked 3.33; and public platform-as-a-service (PaaS), such as Microsoft Azure, 2.5. Private clouds using the IaaS model also ranked 2.5, followed by a private PaaS, ranked at about 2.0. A private cloud is one in which a cloud-designed IT system is operated within a company's own network.
