Types of Web Services in the Cloud Can be thought of as three kinds of services 1. Software as a Service (SaaS)  Software function taken off your computer and hosted online  No need to worry about installation, setup and running of the application - the service provider does that for you E.g. Gmail, Dropbox, Facebook  Sometimes called ‘On-demand Software’

Types of Web Services in the Cloud 2. Platform as a Service (PaaS)  Providers deliver a computing platform typically including operating system, programming language execution environment, database, and web server  Basically gives you a platform in which to develop services at low cost  E.g. Elastic Beanstalk, AppFog 3. Infrastructure as a Service (IaaS)  Providers deliver the equipment used to support operations, including storage, hardware, servers and networking components. Provider owns the equipment and is responsible for housing, running and maintaining it.  E.g. Amazon Web Service, MS Azure, Google Compute Engine  Sometimes called ‘hardware as a service’
