    Study Notes

    IT Infrastructure

    • IT infrastructure is a foundation that enables the execution of a firm's business strategy by providing the necessary technology resources, comprising hardware, software, and services. These resources are shared across the organization to support the development, maintenance, and delivery of IS applications that drive business outcomes.
    • It includes hardware, software, and services such as consulting, education, and training that are shared across the entire firm or business.
    • IT infrastructure is made up of a set of physical devices and software applications that are required to operate the entire enterprise.

    Components of IT Infrastructure

    • Computer hardware platforms
    • Operating system platforms
    • Enterprise software applications
    • Data management and storage
    • Green computing (Green IT) practices and technologies for manufacturing, using, and disposing of computing and networking hardware

    Evaluation of IT Infrastructure

    • There are five stages in the evaluation of IT infrastructure, each representing a different configuration of computing power and infrastructure elements.
    • The stages are:
      • General-purpose mainframe and minicomputer era (1959 to present)
      • Personal computer era (1981 to present)
      • Client/server era (1983 to present)
      • Enterprise computing era (1992 to present)
      • Cloud and mobile computing era (2000 to present)

    Technology Drivers of Infrastructure Evolution

    • Moore's law and microprocessing power
      • Computing power doubles every 2 years
      • Nanotechnology
    • Law of Mass Digital Storage
      • The amount of data being stored each year doubles
    • Metcalfe's Law and network economics
      • The value or power of a network grows exponentially as a function of the number of network members
    • Declining communication costs and the Internet
      • Exponential growth in the size of the Internet
    • Standards and network effects
      • Technology standards
      • Unleash powerful economies of scale and result in price declines
    • Linux and open-source software
      • Produced by a community of programmers
      • Examples: Apache web server, Mozilla Firefox browser, OpenOffice
    • Software for the web: Java, HTML, and HTML5
      • Java Virtual Machine
      • Web browsers
      • HTML and HTML5
      • Ruby and Python
    • Web services and service-oriented architecture
      • Web services
      • XML: Extensible Markup Language
      • SOA: service-oriented architecture
        • Set of self-contained services that communicate with one another to create a working software application
        • Software developers reuse these services in other combinations to assemble other applications as needed
    • Software outsourcing and cloud services
      • Software packages and enterprise software
      • Software outsourcing
      • Cloud-based software services and tools
        • Service Level Agreements (SLAs): formal agreement with service providers
