  9. Where REST fits

  10. Why? ● The Web is a more loosely coupled SOA – Interface and implementation separated ● “Implementation” more than just language, OS, platform, etc.. – also the function performed by the code; its “type” – Stock quote impl != weather forecast impl – A client that knows, a priori, which is which, has an implementation dependency

  11. Why? ● WSDL not part of runtime architecture of Web services systems – If you delete *.WSDL, what breaks? ● HTTP as “void *” – Application-independent Facade

  12. In conclusion ● I used to build CORBA systems – Now I build Web systems ● For similar problems ● The Web as a goal, with REST as a guide
