10. Types of Web Services in the Cloud
Can be thought of as three kinds of services
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, Salesforce.com, Zendesk
Sometimes called ‘On-demand Software’
Designed for end users who wish to consume a product or service
Designed for lots of users who want to do very similar things

11. Types of Web Services in the Cloud
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, Facebook API
Designed for developers to help them reduce cost in providing other consumers a product or service
Designed for medium number of users who want to do a broader range of things

12. Types of Web Services in the Cloud
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’
Designed for network or hardware administrators to help them reduce cost when providing developers a platform on which to develop products or services
Designed for a relatively smaller number of users who want to do very different things
