  • 4.  “Infrastructure-as-a-service – rather than purchasingservers, software, data center space and networkequipment, the vendor provides these services andbills the client based on the amount of resourcesconsumed. Platform-as-a-service – the vendor provides andmanages the operating system, database, andeverything else needed to run certain platforms. Software-as-a-service – instead of businessespurchasing a software license, vendors run thesoftware application for you. The software iscontinually updated behind the scenes.”(Holland)4/29/2013
  • 5. 4/29/2013 SaaS (software as a service) – “This type of cloudcomputing delivers a single application through thebrowser to thousands of customers using amultitenant architecture”. Utility computing - This form of cloud computing isgetting new life from companies such as,Sun, IBM, and others who now offer storage andvirtual servers that IT can access on demand. Web services in the cloud – “Closely related to SaaS,Web service providers offer APIs that enabledevelopers to exploit functionality over the Internet,rather than delivering full-blown application”. Platform as a service - This form of cloud computingdelivers development environments as a service andis considered another form of SaaS.
  • 6. 4/29/2013 MSP (managed service providers) – A managedservice is basically an application exposed to ITrather than to end-users, such as a virus scanningservice for e-mail or an application monitoring serviceand is one of the oldest forms of cloud computing. Service commerce platforms - A hybrid of SaaS andMSP, this cloud computing service offers a servicehub that users interact with and are most commonlyused in electronic trading. Internet integration - The integration of cloud-basedservices is in its early days.
