  3. 3. Facts on Cloud Computing The origin of the term cloud computing is obscure, but it appears to derive from the practice of using drawings of stylised clouds to denote networks in diagrams of computing and communications systems. The internet in diagrams and IT schematics has been represented by a cloud since 1994.The three forms of Cloud Computing: Infrastructure-as-a-Service (IaaS) Platform-as-a-Service (PaaS) Software-as-a-Service (SaaS)
  4. 4. Software as a Service (SaaS)The most popular of these at the moment is Software-as-a-Service(SaaS), this due to the rise of organisations such as Salesforce.com andservices such as Google Apps.SaaS has become very popular due to the pricing models that areavailable to companies which make it a lot cheaper for organisations tohave a particular piece of software. The initial set up fee is a lot lowerso the barriers to entry are much lower. The pricing models tend to beon subscription basis per a user, so you only pay for what you use.Customer Relationship (CRM) is one of the most popular types of SaaS.This is because it can be accessed from anywhere simply by userslogging into a system via the Internet.
