Why SOAP?

• Why is SOAP needed?

• Initially, to get through firewalls:

  • CORBA, DCE and other vehicles use many different ports.
  • HTTP firewalls intervene; only allow passage over port 80.
  • SOAP can send procedure calls using HTTP.

• Additionally, as a common, simple way to describe how to talk to applications.

  • SOAP is transparent (just text).
  • SOAP is not tied to any particular application model.
  • SOAP can be implemented over other communication vehicles besides HTTP.
