The Cloud Web is overtaking/has overtaken desktop Mobile is replacing local Utility-based computing is replacing once-off purchase
Makes resources seem endless Lowers risk in terms of usage (pay as you go)

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 Cloud2. 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’
