Data center in the cloud Web has overtaken local Mobile has overtaken desktop Utility-based computing is replacing once-off purchase Makes resources seem endless through pooling Lowers risk in terms of usage (pay as you go) Demand Capacity Time Resources Demand Capacity Time Resources Static data center Data center in the cloud Slide Credits: Berkeley RAD Lab

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

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

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
