  1. Overview • Web 2.0 has become characterized by applications that connect people and technologies that link data • The Internet makes it possible to access information from any Internet-connected device • Web-based tools for collaboration • Web applications • Other technologies for sharing information Chapter 6: Linking Data

  2. Computing in the Cloud • Cloud computing describes how applications are stored and deployed on a network of Internet servers • Cloud represents the Internet • Cloud computing service providers offer server space and processing • Companies such as Google, Amazon, Microsoft, and Salesforce often operate these servers for many businesses Chapter 6: Linking Data

  3. Computing in the Cloud Chapter 6: Linking Data

  4. Computing in the Cloud • Cloud computing includes three main areas of service: • Infrastructure as a Service (IaaS) • Delivery of a networked computing structure over the Internet • Platform as a Service (PaaS) • Delivery of a computing platform over the Internet • Software as a Service (SaaS) • Delivery of software applications over the Internet • Cloud computing is more cost-effective Chapter 6: Linking Data

  5. Infrastructure as a Service: Computing in the Cloud • Consumers can store photos, music, documents, and other files in the Cloud • Public Cloud • Hybrid Cloud • Private Cloud • Many Cloud storage providers offer limited storage for free, and charge an additional fee for more storage • Freemium business model Chapter 6: Linking Data

  6. Infrastructure as a Service: Computing in the Cloud Chapter 6: Linking Data

  7. Infrastructure as a Service: Computing in the Cloud • A virtual computer is a Web application that provides computing capabilities Chapter 6: Linking Data

  8. Infrastructure as a Service: Computing in the Cloud • Using virtualization, one host machine can operate as if it were several smaller servers Chapter 6: Linking Data

  9. Platform as a Service:Application Development in the Cloud Chapter 6: Linking Data

  10. Platform as a Service:Application Development in the Cloud Chapter 6: Linking Data

  11. Software as a Service:Applications in the Cloud • The Web adds connectivity to many traditionally desktop-hosted applications Chapter 6: Linking Data

  12. Consumer Applications in the Cloud • Cloud computing makes it possible for companies to offer Web-based versions of popular personal computer programs • Gmail • Microsoft Office Outlook Web Access • Google Docs • Google Reader • Google Sites • ZohoWriter • Microsoft Office Live • Sumo Paint Chapter 6: Linking Data

  13. Business Applications in the Cloud • The Salesforce Service Cloud allows businesses to pay as they use services, instead of owning comparable software Chapter 6: Linking Data
