Service Oriented Architectures (SOA) Use Web Services
    These are modular, re-usuable CIT services.
  • One CIT service, such as a calendar service,
    might be re-used in the CRM and ERC applications.
  • They have special interfaces (more later.)
  • They tend to use one of a small set of CIT technologies.
  • They are exposed to the Internet, like cloud services.

Cloud services might be web services, or not. Do you see why we need definitions yet?
